PC-98 Sprite ripping
#3
Hi, I don't know what kind of advice I can offer you in ripping PC98 games. It is a PC. People make their own file format for their games. Companies made game engine for it, like Alicesoft system 3. It also has RPG maker games (Corpse Party).

The only thing I can show you is how Rusty's graphic data looks like:

In this case, the sprite is 1-bpp repeat 5 times. Merging 4 bits together, you will get the palette index. The mask is to remove the background, since not all black pixels are background.

For maps, there are the same thing, but without the mask (so it is repeat 4 times). 256 tiles, with every tile is 32x16 pixel.

And then you'll have to 2x the height to display on screen.

So I just write a script to rip all graphics in the game. The script is on my GitHub:

result:

(it is the skeleton's lower body, and it need to reassemble together with upper body parts!)

Hope that helps, and good luck with your hacking!
