Title: A Gameboy Table File
Post by: Me_Dave on January 10, 2011, 09:43:03 pm
This is dumb, but how do you make a table file for a gameboy rom. Like is there a certain emulator that can help find the hex locations of the font, or is there a document that covers making one for a specific game like Pokemon I can try that if there is one. Although I am not hacking Pokemon it could be a start if I knew what document it was covered in if at all. Please help.

Edit: I know how to make the table file, what I need to know is how to find the data that you put in the table file from inside the rom.

Normally, text characters are just tile indexes. For example, in Pokemon Red, 0x80 being A really just points to the tile 0x80, which has the graphical value of A.

Relative searching is the simplest "caveman" method. Assuming no black magic is involved with the text storage (compression, unusual table patterns, etc.), searching for string patterns using a tool like WindHex is an easy way to identify which hex bytes correspond to which characters. Make sure, of course, that you use like cases - i.e., either ALL UPPERCASE or all lowercase (i.e. if you're looking for the string "House", it may be constructive to search for just "ouse").

Thank you, I'll give relative searching a try. I did find that this emulator http://www.romhacking.net/utils/340/ (http://www.romhacking.net/utils/340/) can help some if there is no compression.

You could also use BGB (http://bgb.bircd.org/)'s VRAM viewer to see what value correspond to each tile (or character).

Thanks I'll give that a try. I was able to make one with search relative.

There is a program to view it by decompressing EpsxE save files
