Loading a BS still image

You need mkpsxiso in your $PATH to generate a PSX disk image.

Compile

make all

make cleansub

MC32 can convert these formats to BS : TIM, RGB, YUV.

Convert your image to a 24bpp TIM with img2tim:

img2tim -bpp 24 -o output.tim input.png

Then use MC32 as instructed below.

Result :

identify bace.tim 
bace.tim TIM 320x240 320x240+0+0 8-bit sRGB 230420B 0.000u 0:00.000

You can convert your image to RGB with:

convert input.png RGB:output.rgb

Result :

identify -size 320x240 -depth 8 RGB:bace.rgb
RGB:bace.rgb=>bace.rgb RGB 320x240 320x240+0+0 8-bit sRGB 230400B 0.000u 0:00.003

You can convert your image to YUV with:

convert input.png UYVY:output.yuv

Result :

dentify -size 320x240 UYVY:bace.yuv 
UYVY:bace.yuv=>bace.yuv UYVY 320x240 320x240+0+0 8-bit YCbCr 153600B 0.000u 0:00.005

Use the MC32 tool conversion tool to import the image, specifying the right dimensions, and convert to bs with those settings :

Note that a BS image must have a width and height that is a multiple of 16

Input: RGB, Output: bs
MDEC version : 2
Custom: Size in sectors or (2048 * sector number) bytes, Variable frame size
