The "game boy" screen affects on the manipulation? If yes, how can i get it? (I play on gambette and don't know to setup on BGB).

yeas u do need it and it cant be done on gambatte but for bgb go to options>system>Enable bootroms and paste this under gbc bootrom gbc_bios.bin If you have any questions just ask me

I did everything you say, but for some reason the screen of BGB is totally black, i tried 3 different roms, but any of them work. Also the commands and the sound still working, but i can't se anything. When i disable the gbc bootrom the game works perfectly. What should i do?

Have you actually downloaded the bootrom? You need to do that, then place it in the same folder as BGB.

You have a link for this bios? I can't find them

Not sure if i can link to that here, but if you google 'gbc bios' you should find it quickly ;)

For some reason i can't find it to run in bgb, only for snes9x , but thanks anyway.

@problemstrol did you find an answer? .. i have the same problem .. even if i downloaded the gbc_bios.bin it always says that its type is snes9x_bios ...

Jesus, what don't you people understand about "Linking ROMs/BIOS files potentially opens the site up to liability"?

Removed the above.

i literally got a notification from speedrun clicked it and it took me to this post, i didnt even look at the date lol
