Is there a way to save Scaling on each core, like

Game Boy/Color 1:1
Game Boy Advance 16:10

Hope you understood what I asked

Each emulator should have its own settings that you have to save once set, don't you use different emulators for GB and GBA?

I don't really understand, you're using different displays, or you want to manually force an image ratio or another on the TV settings?

Retroarch is not the most easy to use emulation solution on the GC, you can use separate standalone emulators as well, this way, you can have different settings between the GB and the GBA side.

I would even dare to say, just use Enhanced mGBA and do not look back at retroarch on GC: viewtopic.php?f=13&t=3129

Maybe the user wants to have full control over the image size... He will only achieve this with Retroarch.

And with the right version, I can play Neo Geo Pocket/Color and PC Engine/CD almost perfectly. I think it's always a valid option.
