Screen Rotation per Rom Help

t_mitch

I've got my screen rotated vertically by editing the boot/config.txt file. But I have one or two games that need to be horizontal.

I've seen a few threads online that talk about setting up the config for each rom, but they all seem to assume some knowledge I don't have.

Where do I find the config file for an individual rom? What exactly do I need to put in it rotate the screen?

Thanks.

@trey_mitchell You create a .cfg file for the ROM - with the ROM name - alongside the ROM file - https://retropie.org.uk/docs/RetroArch-Configuration/#config-hierarchy.

To rotate the display, add

video_allow_rotate=true
video_rotation =  X

where X = 1, 2, 3 = 90, 180, 270 - see https://retropie.org.uk/forum/topic/12539/.

You can also use the RGUI (RetroArch interface) to change the video orientation, then save a game override so you don't have to manually create a .cfg file.

I tried the .cfg file. It goes in the same directory as the rom? If so, that didn't work.

How do I access RetroArch? I've seen several different button combos listed online, but none seem to do anything.

The combination is Hotkey + X, where Hotkey is the button you chose as Hotkey for your gamepad during configuration in Emulationstation. Usually it's Select + X.

No dice. Holding hotkey and x doesn't do anything. Maybe I should start another thread about that?

Could these two issues (not being able to bring up Retroarch and the .cfg files not working) be related?

MAME w/ MAME4All

OK, I switched to LR-MAME2000 and now I can get into Retroarch and after A LOT of hunting and pecking found the setting for screen rotation.

Thanks!

@t_mitch Mame4All is not a Libretro emulator, so the hotkey combination don't apply (and also the .cfg file has no effect). But you found the solution, so that's good.
