(adsbygoogle = window.adsbygoogle || []).push({}); I've been wanting to do this for a while and so I am starting my venture on Rom Hacking.

I haven't been able to locate good tools for the the early Pokemon games Red/Blue/Crystal that has a lot of features jam packed into one. All I have really found is a sprite editor here and there or a starter modifier, no real map/tile editors.

I know it won't be a simple task but I think it would be fun to actually create something that can be used. This is basically a program that I made that reads a small portion of the Pokemon Games hex to identify what game version it is. I didn't have GBA files downloaded and this was something that I wanted to just quickly compile so I didn't bother adding GBA.

The file is 12.5kb and the download is here: You must login or register to view this content.

The reader is very basic, ShowDialog/BinaryReader + positioning where it starts reading at.
