So you could have the letter A at 0x00, x01, 0x0A, 0x10, 0x21, 0x41, 0x81, or elsewhere depending on the game and what the developers felt like. FINAL FANTASY 6 EMULATOR MAC HOW TOWhy is this the case? Because many of these games were made in Japanese using Japanese characters, the developers had no reason to respect the ASCII standard but were more concerned about how to make the best out of the limited memory available. Instead, a custom character encoding is used that doesn't conform to the ASCII standard. Once accomplished, you can decompress the text so that it can be edited then recompress it and feed it back to the game.īut sometimes, none of the above may apply. You'll need to figure out the actual compression pattern either by studying the file structure blindly or by reverse-engineering the game's programming during runtime as it uses the compressed file. There are numerous schemes, and some games have their own unique flavors. Compression is a data transformation operation intended to save space. Fortunately, this is impractical and mostly uncommon. Sometimes, the developers do this on purpose to make the ROM unreadable by hex editors, as is the case for encrypted 3DS ROMs or games with anti-modding measures like God Eater 2 (PSP, JP) and Youkai Watch save files. So you'll have to use the search feature or browse further down the file.
