GBA LZ77 hacking
« on: October 18, 2015, 02:35:28 pm »
I used to talk to Spikeman in here, but I've never seen him online again and he never replied to me anymore, but I learned a great deal with him while we tried to decompress Castlevania Aria of sorrow's graphics. But there are a lot of things I'm still missing about this deal and I hope some of you may help me out a little bit.

I'm using nogba debugger for the adresses, vba to get the pal and GBADecmp to decompress the data from the adresses.

1- We gathered that the game is lz77 compressed, there is no way I can decompress ALL graphic files at once and them compress them again, right?
2 - I'd like for one of you to try this with me. I wanted to grab the name of the game that appears as a graphic in the main menu. I tried a lot of times using spikeman's method (http://www.romhacking.net/forum/index.php/topic,15727.0/nowap.html) but I couldn't. If one of you guys can get this done and explain to me how I'd be really thankful.

For graphics i'd recommened lz77restructor 2. It can compress and decompress lz77 graphics.

I'm interested in this too to see if I can screw around with the Super Mario Advance titles.
