GBA?

Hey I was wondering how can I get the pokemon red game running? I can't find the gba rom and what not, so I can't play the games.

Isn't pokemon red gameboy color?

Maybe you mean Fire Red?

These what you want?

Alright, yea that helped thanks a lot man. Also, how can I get DS games working? Sometimes it says they cannot load. ):

Well, you need to tell us what games don't work, and what flash card you're using (for example R4, DSTT etc).
