5200

[Tobas]

it's incredibly frustrating to play 5200 perfectly on my old 3rd party david marti image, and now, on my fresh buster install, 5200 is completely broken. has anyone found this to be the case? is there a solution?

I am going to assume you are talking about a raspberry pi and a pre-made image. Problem with a pre-made image is it can be changed or altered so we have no idea how to fix it..

but check to make sure you have your bios for the 5200 in the correct place and you have the emulator (atari800 I think it is) set to load 5200 games instead of the computer. If it is retropie..then also make sure the emulator is set correctly in the emulator menu (normally accessed by pressing a button after a launch of a game from the emulator and check the default emulator.

That's all I can suggest to you with so little information.

Its not broken, you just have to understand how a base Retropie build works and what extra manual steps you can do to set it up the same as your old Pi 3 image.  These are manual tweaks to setup the Atari 5200 system to auto-boot as an Atari 5200 instead of an Atari 800.

As mentioned above, make sure you have the BIOS files in the proper place.

Then update/create these 3 files in /opt/retropie/configs/atari5200 and you should be good to go.
