I hope you finish it ^^

I actually got a reply. No sprite sheet available but I can go ahead to rip them... I still need other sprites, though.

mapar007, do you know any dissembler that can help to grab the sprites data? Output in .bin file or just some hex, I just need that and I am able to put in .bmp or other image format.
 If you currently don't know, leave it to me. I ask because you seem to have tested some dissemblers.

Usually, I just use print screen several times when playing the game on emulator then resize then convert to black and white, but the issue is that if a game is really hard (like this one) it takes ridiculous amount of time to rip all sprites. That said, I have some other sprites somewhere that I will post soon, but most are either 16x16 or they are monochrome 8x8

That is why I am going into dissemble the game and find the data for the graphics. Generally graphics come last in the program. Also you can easily (somewhat) find pointers to the graphics.

And I already know programs and ways to convert the hex text into image files.

Most sprites I rip is from eye. I haven't tried the print screen method...

Ah ok. Btw you might want to try Dwedit dissassembler on Ticalc.org. I myself couldn't run it the last time I tried it (got an error about missing ocx or dll files but that was back in 2004 or 05) but other people had no problem with it. Idk if it dissassembles everything correctly, though, like the sprites data

That is what I needed, thanks DJ. Great dissembler, it guesses the data for me! Nice... In some minutes, I will have the sprite sheet.
