I think while looking for more info on hacking a specific arcade game. I've found this document on hacking the game Tapper.
Of course I have absolutely no interest in hacking Tapper. Nor do I have the ROM file.
But then it actually mentions a problem I've encountered while trying to hack arcade games, More on that later. A few years ago I tried asking you guy on help identifying the color palette in an arcade game. That game was Donkey Kong... I didn't wanna say it because I didn't want to for whatever reason. But I did find the palette data. And it turns out the colors are preset similar to the NES/Atari 2600 as opposed to the Genesis/SNES with manually changeable RGB values.
So then I put in numbers 0-FF in what I assume is the palette data to get a full scope of all the colors I can use. Put the modified file in the ROM zip file. Then... the ROM doesn't work... MAME refuses to load it like a piece of crap! Like half of the ROMs in my collection. At first I thought the emulator was just being fussy on what type of ROMs it will load. But then years later, I read the document on hacking Tapper and I found out this... That if you hack your ROM AT ALL!!!! whatsoever. The checksum won't match up and MAME will not read it.
So I assume that copying files into the ZIP file will give out a false checksum. So is there a way I can edit ZIP files uncompressed? without extracting the files first?
