[ASM & Hex] Identifying rom version

[MegaMetapod]

Hi,

I'm playing with some code here, I want to see if I can make a tool out of it. However, I want to see if it is possible to make this cross-version. I know the name of the game is practically attach to the top of the rom, so it is easy to know the specific version and gen. Still, is there a way to know which language version or build is the rom (you know, like Fire Red 1.0 or Fire Red 1.1)? I can imagine it being more difficult to get the build number, but I have a moderate hope that there would be an easy way to find the language. Any ideas here?

The game codes represent the version and I think also the language....
As BPRE means fire red (us)
BPEE means emerald(us) and so on
The pge ini file has all the information about it, if you can understand it ;)

while i don't think i've seen it used in tools previously, here's some ways to identify roms

Cool. Thnx, that's very helpful. Any idea if it is possible to identify them in Gen 1? I think those say only POKEMON BLUE or POKEMON RED but no language byte as the further gens have.
