Oh my god it works!! thank you rockaddiced! You just rescued my girlfriends birthday works perfectly!

Hmm, I tried it with a german and a USA rom, but it does not work here are some screenshots: Any idea?

Hello Guys, first of all I would like to say thanks to the creators of recalbox, its a great project and I love to use it!   Unfortunatly I did not find a solution for my problem myself. Yesterday I was trying to play Pokemon Sapphire for GBA, but when I start the rom, it returned to recalbox after a while. I already included the gba_bios.bin file and other games like sonic work on the GBA emulator. Only Pokemon Sapphire and Rubin doesnt work. In another thread I found out that it could have something to do with a game_config.txt file, but I don't know where I should put this file, I already tried to put it in \RECALBOX\System and \RECALBOX\gameboyadvance but it did not work. I would love to play Pokemon since my GBA does not work anymore, could someone help me?
