TIM files

Standard bitmap images that can be transferred directly to the PSX VRAM.

Can be 4bit or 8bit with a CLUT, 16bit or 24 bit in direct color.

You can access the TIM mode through TIM_IMAGE->mode. Mode can be :

0: 4bits b0
1: 8 bits b1
2: 16 bits b10
3: 24bits b11
4: mixed b100

See FileFormat47.pdf, p.179

Tools

You can use open source tools : Gimp, Aseprite

To convert your image files to TIM, use IMG2TIM :

4bpp and 8bpp specificities

If you want to generate 4bpp and 8bpp TIMs, your original image must be in indexed mode with a palette.

For 8bpp, < 256 colors
For 4bpp, < 16 colors, and size must be a multiple of 4

You can use TIMTOOL.EXE from legacy PsyQ to check your TIM files, or use Lameguy64's TIMedit
