Compressed Hex and Text Editing
« on: June 11, 2013, 08:38:22 am »
Hello

What is the best way to figure out ASCII values for compressed hex formats? I'm trying to get a text dump, but figuring out the hex values feels like a daunting task.

Thanks

Uhm, you don't need a table, you need to decompress the text. Only then can you worry about what the meaning of the decompressed data is.

Each game is different, even for the same type of compression you may have to write your own program. You'll have to figure out what type of compression the game uses and then figure out the best way of attacking it. Sometimes you can get through it in hex if the encoding is simple.

Well, the game is Dragon Ball Z: Legendary Super Warriors, one of my favorites.

My goal is to dump all text within the game, which may reveal some interesting secrets for the fan base.

I've messed around with this stuff on a casual basis before, but I am not sure how to identify a compression format within a game.

Are there any strategies for this?

Look up the Art of Romhacking. There is a nice beginner level section on compression that details several formats you might run into. There are also a couple of nice docs right here in the Database.
