Aeon Genesis is working on Ganbare Goemon 2. Proof: This link.

The other two I have yet to find one either being reported as working on or even attempted.

That also explains Zig Zag Cat, which also has compression.

Zig Zag Cat, according to KingMike, has LZ compression. For the Ganbare Goemon games, I'm not so sure myself. Sorry, but I don't know ASM that well.

On the Essence of ROM Hacking

Contrary to popular belief, translations usually aren't one-man jobs. You have a hacker who rips the script out of the game and a translator who knows the source and target languages who translates it. So, you see, you don't have to know the language of the game you want translate (Japanese, for instance). You will most likely need to familiarize yourself with the language's writing system to produce the script.

ASM knowledge is not always necessary, but it's always extraordinarily useful if you want to produce something that looks professional.

That's what tables are for. ^_^

Tables are just ordinary text files with the ".txt" replaced with a ".tbl" for clarity's sake. Okay, so if you're working with Japanese, they're not going to be ordinary text files, they're going to be Unicode or Shift-JIS or some such, but you get the basic idea: they can be opened in a text editor (Notepad works, but JWPce is better) and edited without having to resort to fancy esoteric tools. Tables are what allow the fancy esoteric tools to display game text properly. :3

If you know hex, then you can make a table. A table is a long list of hex codes and their textual counterparts:


...And so on. Mind you, this is just a sample: building a table usually requires you find the game's font and do a bit of relative searching based on the patterns you find. And if you're really, really stumped, you can boot up the game in an emulator with trace functions, slam a breakpoint on the place in memory where text gets copied to, then trace until you figure out which instruction loads text from the ROM and find out what hex codes represent what characters that way.
