Here's the GBAMP rom map for all you rom hackers out there!
Each page is 16 kilobytes. (0x4000 bytes)
The chinese version contains a full 12x11 chinese font from page 24 to 31. Each character contains 4 bits of padding at the end to make the next character start at a byte address. So the chinese version is 512k, not 1024k.
I still need to know where the bookmarks are stored, and if the empty areas are really empty or not. Pages 4-11 seem to contain code, but when viewed in a graphics editor of 512 bytes wide, you can see distinct vertical patterns every 128 bytes, suggesting it may be data.
