These are my hacking notes on Sonic Advance. It's not much, but it should help stir something up regarding Advance hacking.

Files included:
arthack  -  This includes a list of offsets showing were a lot of art is, if you want to do an art hack.
advother  -  This doesn't have much, but shows the offset for "part 1" of the Title Screen art. Use a program such as TilEd to edit the art, as TLP doesn't support 8bpp for art.
advmem  -  This includes a small bit on the memory for Sonic advance.
NGHZ2  -  This includes a list of offsets regarding a load of info on Neo Green Hill Zone Act 1. It also explains a few formats, including level layout, 128x128 mappings, and palette.
SADV_E.sapt  -  This file is for Erik JS' Sonic Advance PalTool. It has been translated into English, and has quite a few additions to it.


This 'guide' is no guide at all. In fact, it's barely got any info in it. If you'd like to hunt for other level specific info, such as layouts for another layout, locate the foreground art for that level/act, and after that, the data should be there in the following order: foreground art, collision, 128x128 mappings, and the level layout. After level layout, some stuff regarding animated patterns may be present.
