## Pinouts - Controller Ports and Memory-Card Ports
#### Controller Ports and Memory-Card Ports
```
1 In JOYDAT Data from joypad/card (data in) _______________________
2 Out JOYCMD Data to joypad/card (command out) | | | |
3 - +7.5V +7.5VDC supply (eg. for Rumble) | 9 7 6 | 5 4 3 | 2 1 | CARD
4 - GND Ground |_______|_______|_______|
5 - +3.5V +3.5VDC supply (normal supply) _______________________
6 Out /JOYn Select joypad/card in Slot 1/2 | | | |

8 In /IRQ10 IRQ10 (Joy only, not mem card) \______|_______|______/
9 In /ACK IRQ7 Acknowledge (each eight CLKs)
Shield Ground (Joypad only, not memory card)
```
![Controller pinout](controller-pinout.jpg)
/JOYn are two separate signals (/JOY1 for left card/pad, /JOY2 for right
card/pad) (whether it is an card or pad access depends on the first CMD bit).
All other signals are exactly the same on all four connectors (except that pin8
and shield are missing on the card slots).<br/>
#### Pin8 (/IRQ10)
Most or all controllers leave pin8 unused, the pin can be used as lightpen
input (not sure if the CPU is automatically latching a timer somewhere?), if
there's no auto-latched timer, then the interrupt would be required to be
handled as soon as possible; ie. don't disable interrupts, and don't "halt" the
CPU for longer periods (as far as I understood, the GTE can halt the CPU when
trying to read results of incomplete operations; to avoid that, one could wait
by software, eg. inserting NOPs, before reading GTE results...?)<br/>
(Some (or maybe all?) existing psx lightguns are reportedly connected to the
Video output on the Multiout port for determining the current cathode ray
position though).<br/>
## Pinouts - Audio, Video, Power, Expansion Ports
#### AV Multi Out (Audio/Video Port)
```
1 RGB-Video Green
2 RGB-Video Red
3 Supply +5.0V (eg. supply for external RF adaptor)
4 RGB-Video Blue
5 Supply Ground
6 S-Video C (chrominance)
7 Composite Video (yellow cinch)
8 S-Video Y (luminance) ____________________________
9 Audio Left (white cinch) | |
10 Audio Left Ground | 12 11 10 9 8 7 6 5 4 3 2 1 |
11 Audio Right (red cinch) |____________________________|
12 Audio Right Ground
Shield Video Ground
```
The standard AV-cable connects only to Pins 7,9,10,11,12,Shield (with pin 1 and
3 and Shield shortcut with each other, used for both audio and video ground).<br/>
The plug on that cable does have additional sparings for pin 1,3,5 (though
without any metal-contacts installed in there) (pin 3,5 would be used as supply
for external RF modulators) (no idea what pin 1 could be used for though?).<br/>
RGB displays may (or may not) be able to extract /SYNC from the Composite
signal, if that doesn't work, note that /SYNC (and separate /VSYNC, /HSYNC
signals) are found on the GPU pinouts, moreover, the GPU outputs 24bit digital
RGB.<br/>
Not sure if a VGA monitor can be connected? The SYNC signals are there (see GPU
pinputs), but the vertical resolution is only 200/240 lines... standard VGA
displays probably support only 400/480 lines (or higher resolutions for newer
multisync SVGA displays) (as far as I know, the classic 200 lines VGA mode is
actually outputting 400 lines, with each line repeated twice).<br/>
#### Parallel Port (PIO) (Expansion Port) (CN103)
This port exists only on older PSX boards (not on newer PSX boards, and not on
PSone boards).<br/>
The parallel port is used by Gameshark, Game Enhancer II, and Gold Finger cheat
devices (not used by the Code Breaker CDROM cheat software).<br/>

```
Lots of pins are still unknown?<br/>
```
EDIT: see http://cgfm2.emuviews.com/new/psx-pio.png
apparently, many of the "unknown" pins are just GROUND, is that possible?
```
#### Internal Power Supply (PSX)
The PSX contains an internal power supply, however, like the PSone, it's only
having a "Standby" button, which merely disconnects 3.5V and 7.9V from the
mainboard. The actual power supply remains powered, and wastes energy day and
night, thanks Sony!<br/>
#### External Power Supply (PSone)
```
Inner +7.5V DC 2.0A (inside diameter 0.8mm)
Outer GND (outside diameter 5.0mm)
```
## Pinouts - SIO Pinouts
#### Serial Port
That port exists only on original Playstation (not on the PSone). The shape of
the Serial Port is identical to the 12pin Multiout (audio/video) port, but with
only 8pins.<br/>
```
1 SIO1 In RXD receive data (from remote TXD)
2 SIO2 - VCC +3.5VDC (supply, eg. for voltage conversion)
3 SIO3 In DSR (from remote CTS) _________________
4 SIO4 Out TXD transmit data (to remote RXD) | |
5 SIO5 In CTS clear to send (from remote RTS) | 8 7 6 5 4 3 2 1 |
6 SIO6 Out DTR (to remote DSR) |_________________|
7 SIO7 - GND Ground (supply, eg. for voltage conversion)
8 SIO8 Out RTS request to send (to remote CTS)
Shield GND Ground (to/from remote GND)
```
Can be used to communicate with another PSX via simple cable connection. With
an external RS232 adaptor (for voltage conversion) it could be also used to
communicate with a PC, a mouse, a modem, etc.<br/>
#### PSone Serial Port
The PSone doesn't have an external serial connector, however, easy to use
soldering points for serial port signals are found as cluster of 5 soldering
points (below CPU pin52), and a single soldering point (below CPU pin100),
arranged like so (on PM-41 boards) (might be different on PM-41(2) boards):<br/>
```
CPU70.RTS
CPU71.CTS CPU74.TxD
CPU72.DTR CPU75.RxD CPU73.DSR
```
The three outputs (RTS,DTR,TXD) are left floating, the RXD input is wired via a
1K ohm pull-up resistor to 3.5V, the other two inputs (CTS,DSR) are wired via
1K ohm pull-down resistors to GND.<br/>
If you want to upgrade the PSone, remove that resistors, and then install the
PSX-style serial circuit (as shown below), or, think of a more simplified
circuit without (dis-)inverted signals.<br/>
#### PSX Serial Port Connection (PU-23 board) (missing on PM-41 board)
The PSX serial circuit basically consists of a few transistors, diodes, and
resistors. The relevant part is that most of the signals are inverted -
compared with RS232 signals, the CPU uses normal high/low levels (of course
with 0V and 3.5V levels, not -12V and +12V), and the signals at the serial port
socket are inverted. Ie. if you want to built a RS232 adaptor, you must either
externally undo the inversion, or, disconnect the transistors, and wire your
circuit directly to the CPU signals.<br/>

```
All six signals are passed through fuses (or loops or so). The three inputs
have 1K ohm pull-ups, and diodes as protection against negative voltages, two
of the inputs are inverted via transistors, with 470 ohm pull-ups at the CPU
side, the other input is passed through 22 ohm to the CPU. The three outputs
are also passed through 22 ohm, one of them having a diode as negative voltage
protection, the other two are inverted via transistors (which may also serve as
negative voltage protection).<br/>
Note that there is no positive voltage protection (ie. +12V inputs would do no
good, also strong -12V inputs might overheat the diodes/fuses, so if you want
to use RS232 voltages, better use a circuit for voltage conversion).<br/>
#### Serial RS232 Adaptor
The PSX serial port uses 0V/3.5V logic, whilst RS232 uses -5V/+5V...-15V/+15V
logic. An example circuit for converting the logic levels would be:<br/>

```
Parts List: 1 or 2 MAX232 chips (voltage conversion), 0 or 1 7400 (NAND, used
as inverter), 4 or 8 1uF/16V capacitors, 1x 10uF/16V capacitor, 1x 9pin male
SubD plug.<br/>
The four inverters are needed only for external adapters (which need to undo
the transistor inversion on the PSX mainboard) (ie. the inverters are not
needed when when connecting the circuit directly to the PSX CPU).<br/>
The second MAX232 chip is needed only if DTR/DSR "not ready" conditions are
required (for an "always ready" condition: DSUB.4.DTR can be wired to -8.5V,
which is available at Pin6 of the first MAX232 chip, and PSX.DSR can be wired
to +3.5V).<br/>
With the above DSUB pin numbers, peripherals like mice or modems can be
connected directly to the circuit. For connection to another computer, use a
"null modem" cable (with crossed RXD/TXD, RTS/CTS, DTR/DSR wires).<br/>
The circuit works with both VCC=5V (default for MAX232) and with VCC=3.5V
(resulting in slightly weaker signals, but still strong enough even for serial
mice; which are mis-using the RS232 signals as power supply).<br/>
## Pinouts - Chipset Summary
#### PSX/PSone Mainboards
```
Board Expl.
PU-7 PSX, with AV multiout+cinch+svideo, GPU in two chips (160+64pins)
PU-8 PSX, with AV multiout+cinch, four 8bit Main RAM chips
EARLY-PU-8: "PU-8 1-658-467-11, N4" --> old chipset, resembles PU-7
LATE-PU-8: "PU-8 1-658-467-22, N6" --> new chipset, other as PU-7
PU-9 PSX, without SCPH-number (just sticker saying "NOT FOR SALE, SONY)
PU-16 PSX, with extra Video CD daughterboard (for SCPH-5903)
PU-18 PSX, with AV multiout only, single 32bit Main RAM (instead 4x8bit)
PU-20 PSX, unknown if/how it differs from PU-18
PU-22 PSX, unknown if/how it differs from PU-18
PU-23 PSX, with serial port, but without expansion port
PM-41 PSone, older PSone, for GPU/SPU with RAM on-board (see revisions)
PM-41(2) PSone, newer PSone, for GPU/SPU with RAM on-chip
```
There are at least two revisions of the "PM-41" board:<br/>
```
PM-41, 1-679-335-21 PSone with incomplete RGB signals on multiout port
PM-41, 1-679-335-51 PSone with complete RGB signals on multiout port
```
The "incomplete" board reportedly requires to solder one wire to the multiout
port to make it fully functional... though no idea which wire... looks like the
+5V supply? Also, the capacitors near multiout are arranged slightly
differently.<br/>

Old 160-pin GPU is used on PU-7 boards and EARLY-PU-8 boards.<br/>
#### IC203 - Sony CXD8514Q - Old 160pin GPU for use with Dual-ported VRAM
Unlike the later 208pin GPU's, the old 160pin GPU has less supply pins, and, it
doesn't have a 24bit RGB output (nor any other video output at all), instead,
it's used with a RGB D/A converter that reads the video data directly from the
Dual-ported VRAM chips (ie. from special RAM chips with two data busses, one
bus for GPU read/write access, and one for the RGB video output).<br/>

#### IC207 - SONY CXD2923AR - Digital VRAM to Analog RGB Converter (for old GPU)
This chip is used with the old 160pin GPU and two Dual-ported VRAM chips. The
2x16bit databus is capable of reading up to 32bits of VRAM data, and the chip
does then extract the 15bit or 24bit RGB values from that data (depending on
the GPU's current color depth).<br/>
The RGB outputs (pin 5,7,9) seem to be passed through transistors and
capacitors... not sure how the capacitors could output constant voltage
levels... unless the RGB signals are actually some kind of edge-triggering PWM
pulses rather than real analog levels(?)<br/>

Used only on older boards (eg. PU-7, PU-8, PU-16), newer boards generate
composite signal via 48pin IC502.<br/>
Pin7 (NPIN): NTSC=VCC, PAL=GND. Pin6 (SCIN aka FSC): Sub Carrier aka PAL/NTSC
color clock, which can be derived from three different sources:<br/>
```
GPU pin 145 (old 160-pin GPU)
GPU pin 154 (new 208-pin GPU)
IC204 (on later boards, eg. PSone)
```
for the color clocks from GPU pins, the GPU does try to automatically generate
PAL or NTSC clock depending on current frame rate, which is resulting in
"wrong" color clock when chaning between 50Hz/60Hz mode).<br/>

Pin 3..8 (analogue outputs) are passed via external 75 ohm resistors.<br/>
Pin 6,7 additionally via 220uF. Pin 8 additionally via smaller capacitor.<br/>
Pin 10 (YTRAP) wired via 2K7 to 5.0V.<br/>
Pin 1,44,46,48 (can) connect via capacitors to ground (only installed for 44).<br/>
The 4.4MHz clock is obtained via 2K2 from IC204.Pin6.<br/>
The /PAL pin can be reportedly GROUNDED to force PAL colors in NTSC mode, when
doing that, you may first want to disconnect the pin from the GPU.<br/>
Note: Rohm BH7240AKV has same pinout (XXX but with pin7/pin8 swapped?)<br/>
#### Beware
Measuring in the region near GPU Pin10 is the nocash number one source for
blowing up components on the mainboard. If you want to measure that signals
while power is on, better measure them at the CPU side.<br/>

This chip isn't connected directly to the CPU, but rather to a Fifo Interface,
which is then forwarding data to/from the CPU. On older PSX boards, that Fifo
Interface has been located in a separate chip, on newer PSX boards and PSone
boards, the Fifo stuff is contained in the SPU chip. The CDROM has a 32K
buffer, which is also implemeted at the Fifo Interface side.<br/>

#### HC05 - 32pin/64pin Versions
Sony's Digital Joypad and Mouse contain 32pin CPUs, which are probably also
HC05's:<br/>
[Pinouts - Component List and Chipset Pin-Outs for Digital Joypad, SCPH-1080](pinouts.md#pinouts-component-list-and-chipset-pin-outs-for-digital-joypad-scph-1080)<br/>
Moreover, some old memory cards contain a 64pin Motorola SC419510FU (probably
also a HC05) with separate Atmel AT29LV010A (128Kx8 FLASH).<br/>

Uses standard EPROM pinouts, VCC is 3.5V though, when replacing the ROM by an
EPROM, it may be required to replace the supply by 5V. Note that, on PM-41
boards at least, Pin 1 is connected to A19 (allowing to install a 1MB BIOS chip
on that board, however, normally, a 512KB BIOS chip is installed, and, the CPU
is generating an exception when trying to access more than 512KB, but that 512K
limit can be disabled via memory control registers).<br/>

The chip supports 8bit/16bit mode, on the PSX D0-D14 are actually wired, but
A0/D15 is wired to A0, and /BYTE is wired to GND, so 16bit mode doesn't work.<br/>

Note: SPU-RAM supply can be 3.5V (PU-8), or 5.0V (PU-22 and PM-41).<br/>
Note: The /CASL and /CASH pins are shortcut with each other on the mainboard,
both wired to the /CAS pin of the SPU (ie. always accessing 16bit data at
once).<br/>
Note: The TSOP-II package (18mm length, super-flat and with spacing between pin
10/11 and 30/31) is used on PU-23 boards. The pinouts and connections are
identical for SOJ and TSOP-II.<br/>
Note: Nippon Steels NN514256-series is normally 256Kx4bit, nethertheless, for
some bizarre reason, their 256Kx16bit chip is marked "NN514256ALTT"... maybe
that happened accidently in the manufacturing process.<br/>

Newer boards often have 2MB VRAM installed (of which only 1MB is used,
apparently the 2MB chips became cheaper than the 1MB chips). At the chip side,
the only difference is that Pin30 became an additional address line (that,
called A8, and, accordingly, the old A8,A9 pins were renamed to A9,A10). At the
mainboard side, the connection is exactly the same for both 1MB and 2MB chips;
Pin30 is grounded on both PU-23 boards (which typically have 1MB) and PM-41
boards (which typically have 2MB).<br/>
Note: The PM-41(2) board has on-chip RAM in the GPU (no external memory chip).<br/>
## Pinouts - CLK Pinouts
The "should-be" CPU clock is 33.868800 Hz (ie. the 44100Hz CDROM/Audio clock,
multiplied by 300h). However, the different PSX/PSone boards are using
different oscillators, multipliers and dividers, which aren't exactly reaching
that "should-be" value. The PSone are using a single oscillator for producing
CPU/GPU clocks, and for producing the TV/color signal:<br/>
```
For PAL, Fsc=4.43361875MHz (5^6*283.75Hz+25Hz) --> 4*Fsc=17.734MHz
For NTSC, Fsc=3.579545MHz (4.5*455/572 MHz) --> 4*Fsc=14.318MHz
```
#### PSone/PAL - IC204 8pin - "CY2081, SL-509" or "2294A, 1913"
Clock Multiplier/Divider<br/>
```
1 53MHz ;17.734MHz*3 = 53.202 MHz (?)
2 GND
3 X1 17.734MHz
4 X2 17.734MHz
5 67MHz ;17.734MHz*3*2*7/11 = 67.711636 MHz (?)
6 4.4Mhz ;17.734MHz/4 = 4.4335MHz (?) ;via 2K2 to IC502.pin15
7 3.5V
8 3.5V
```
#### PSone/NTSC - IC204 8pin "CY2081 SL-500" (PSone, and PSX/PU-20 and up)
Unknown. Uses a 14.318MHz oscillator, so multiply/divide factors must be
somehow different.<br/>
```
3*3*7*5/2/11 = 14.3181818
3*3*7*7*100 = 44100
```
The "optimal" conversion would be (hardware is barely able to do that):<br/>
```
14.3181818 * 3*7*11*64 / (5*5*5*5*5) = 67.737600
```
So, maybe it's doing<br/>
```
14.3181818 * 2*2*13/11 ... or so?
```
#### PSX/PAL
PU-7 and PU-8 boards are using three separate oscillators:<br/>
```
X101: 67.737MHz (div2 = CPU Clock = 33.8685MHz) (div600h = 44.1kHz audio)
X201: 53.20MHz (GPU Clock) (div12 = PAL color clock)
X302: 4.000MHz (for CDROM SUB CPU)
```
PU-18 does have same X101/X201 as above, but doesn't seem to have X302.<br/>
#### PSX/NTSC
PU-7 and PU-8 boards are using three separate oscillators:<br/>
```
X101: 67.737MHz (div2 = CPU Clock = 33.8685MHz) (div600h = 44.1kHz audio)
X201: 53.69MHz (GPU Clock) (div15 = NTSC color clock)
X302: 4.000MHz (for CDROM SUB CPU)
```
PU-20 works more like PSone (a single oscillator, and CY2081 SL-500 divider)<br/>

## Pinouts - Memory Cards
#### Sony Playstation Memory Card (SCPH-1020)
The "SONY CXD8732AQ" chip is installed on memory cards with "SPC02K1020B"
boards, however, the text layer on the board says that it's an "LC86F8604A"
chip. So, the CXD8732AQ is most probably a standard LC86F8604A chip (more on
that below) with a Sony Memory Card BIOS ROM on it.<br/>
The "SONY CXD8732AQ" comes in a huge 64pin package, but it connects only to:<br/>
```
5 = /IRQ7 (via 22 ohm) 2 = /RESET (from U2)
6 = JOYCLK (via 220 ohm) 30,31 = CF1,CF2 (12 clock pulses per 2us)
7 = /JOYn (via 220 ohm) 14,16,25,32,38,39,61 = 3.5V (via 3.3 ohm)
12 = JOYCMD (via 220 ohm) 8,15,28,29 = GND
13 = JOYDAT (via 22 ohm) All other pins = Not connected
```
Aside from that chip, the board additionally contains some resistors,
capacitors, z-diodes (for protection against too high voltages), a 6MHz
oscillator (for the CPU), and a 5pin reset generator (on the cart edge
connector, the supply pins are slightly longer than the data signal pins, so
when inserting the cartridge, power/reset gets triggered first; the 7.5V supply
pin is left unconnected, only 3.5V are used).<br/>
Caution: The "diagonal edge" at the upper-left of the CXD8732AQ chip is Pin 49
(not pin 1), following the pin numbers on the board (and the Sanyo datasheet
pinouts), pin 1 is at the lower-left.<br/>
#### Sanyo LC86F8604A
8bit CPU with 132Kbyte EEPROM, 4Kbyte ROM, 256 bytes RAM, 2 timers, serial
port, and general purpose parallel ports. The 132K EEPROM is broken into 128K
plus 4K, the 4K might be internally used by the CPU, presumably containing the
BIOS (not too sure if it's really containing 4K EEPROM plus 4K ROM, or if it's
meant to be only either one).<br/>

Ports P10..P17 have multiple functions (I/O port, data bus, serial, etc):<br/>
```

P11/DQ1/SCLK0/FSCLK P13/DQ3 P15/DQ5 P17/DQ7/SO0/FRW
```
In March 1998, Sanyo has originally announced the LC86F8604A as an 8bit CPU
with "2.8V FLASH, achieved for the first time in the industry", however,
according to their datasheet, what they have finally produced is an 8bit CPU
with "3.5V EEPROM". Although, maybe the 3.5V EEPROM version came first, and the
2.8V FLASH was announced to be a later low-power version of the old chip;
namely, otherwise, it'd be everyones guess what kind of memory Sony used in
memory cards before 1998?<br/>

#### Note
Instead of the above internal mod, the nocash kernel clone can be also
installed on cheat devices, which do also include DB25 connectors for parallel
port uploads, too.<br/>
For DB25 parallel port uploads, do the following mods to the cheat device:<br/>
```
- Datel: use the FiveWire mod to get it parallel port compatible
- Xplorer: simply wire DB25./INIT to EXP./RESET (with diode, if needed)
```
## Mods - PAL/NTSC Color Mods
The PSX hardware is more or less capable of generating both PAL and NTSC
signals. However, it's having the bad habbit to do this automatically depending
on the game's frame rate. And worse, it's doing it regardless of whether the
board is having matching oscillators installed (eg. a PAL board in 60Hz mode
will produce NTSC encoding with faulty NTSC color clock).<br/>
```
color encoding PAL NTSC
color clock 4.43361875MHz 3.579545MHz
frame rate 50Hz 60Hz
```
#### RGB Cables
RGB cables don't rely on composite PAL/NTSC color encoding, and thus don't need
any color mods (except, see the caution on GNDed pins for missing
53.20MHz/53.69MHz oscillators below).<br/>
#### Newer Consoles (PU-22, PU-23, PM-41, PM-41(2))
These consoles have 17.734MHz (PAL) or 14.318MHz (NTSC) oscillators with
constant dividers, so the color clock will be always constant, and one does
only need to change the color encoding:<br/>
```
/PAL (IC502.pin13) ---/cut/--- /PAL (GPU.pin157)
/PAL (IC502.pin13) ----------- GND (PAL) or VCC (NTSC)
```
This forces the console to be always producing the desired composite color
format (regardless of whether the GPU is in 50Hz or 60Hz mode).<br/>
That works for NTSC games on PAL consoles (and vice-versa). However, it won't
work for NTSC consoles with PAL TV Sets (for that case it'd be easiest to
install an extra oscillator, as done on older consoles).<br/>
#### Older Consoles (PU-7, PU-8, PU-16, PU-18, PU-20)
These consoles have 53.20MHz (PAL) or 53.69MHz (NTSC) oscillators and the GPU
does try to change the clock divider depending on the frame rate (thereby
producing a nonsense clock signal that's neither PAL nor NTSC). Best workaround
is to install an extra 4.43361875MHz (PAL) or 3.579545MHz (NTSC) oscillator
(with internal amplifier, ie. in 4pin package, which resembles DIP14, hence the
pin 1,7,8,14 numbering):<br/>
```
GPU ------------------/cut/--- CXA1645M.pin6 SCIN
GPU ------------------/cut/--- CXA1645M.pin7 /PAL
Osc.pin14 VCC ---------------- CXA1645M.pin12 VCC (5V)
Osc.pin7 GND ---------------- CXA1645M.pin1 GND
Osc.pin8 OUT ---------------- CXA1645M.pin6 SCIN
Osc.pin1 NC --
GND (PAL) or VCC (NTSC) ------ CXA1645M.pin7 /PAL
```
Caution: Many mainboards have solder pads for both 53.20MHz and 53.69MHz
oscillators, the missing oscillator is either GNDed or shortcut with the
installed oscillator (varies from board to board, usually via 0 ohm resistors
on PCB bottom side). If it's GNDed, remove that connection, and instead have it
shortcut with the installed oscillator.<br/>
Alternately, instead of the above mods, one could also install the missing
oscillator (and remove its 0 ohm resistor), so the board will have both
53.20MHz and 53.69MHz installed; that will produce perfect PAL and NTSC signals
in 50Hz and 60Hz mode accordingly, but works only if the TV Set recognizes both
PAL and NTSC signals.<br/>
#### Notes
External 4.433MHz/3.579MHz osciallors won't be synchronized with the GPU frame
rate (normally you don't want them to be synchronized, but there's some small
risk that they might get close to running in sync, which could result in static
or crawling color artifacts).<br/>
For the CXA1645 chip modded to a different console region, one should also
change one of the resistors (see datasheet), there's no noticable difference on
the TV picture though.<br/>
#### Region Checks
Some kernel versions contain regions checks (additionally to the SCEx check),
particulary for preventing NTSC games to run on PAL consoles, or non-japanese
games on japanese consoles. Some PAL modchips can bypass that check (by
patching the region byte in BIOS). Expansions ROMs or nocash kernel clone could
be also used to avoid such checks.<br/>
