GBC and ATARI 2600 aspect ratio change + PC games?

[Haris1977]

Hello again:P

How can i change the aspect ratio (to 4:3 i guess) of these two emulators (only those 2):

1 – gba
2- atari 2600

Screen is wide and the graphics are huge. Also how can i play doom like games (where do i put files, what files do i need, input config file)??

Thanks!

Each emulator has a retroarch.cfg file that will override the main config file in the all directory. To edit it, you can use the command

sudo nano /opt/retropie/configs/atari2600/retroarch.cfg

For GBC, you can change atari2600 to gbc.

For Atari 2600, I added the line below and saved the file.

video_aspect_ratio = 0.83
