Hi,

Is it possible to install an older version of main on top of a newer? The latest update came with some issues for me...

No

Well you could have multiple ones but only one called Mister, so you would have to rename and reboot every time which defeats the purpose

Thanks! I figured. I wish past me was better at backing up...

You can still download from the repository an older version of Main and install it in place of the current one, but it will most likely break some cores that rely on features implemented in the newer versions of Main.
As FPGA64 mentioned, you can have multiple versions of Main but you will have to rename the one you want to use to Mister and reboot the system.

It's entirely possible, and worth trying if something doesn't work for you. I have done it quite often. Of course, you do need to remember that it's a short term fix, and that you did it, in case something else gets broken and you wonder why. But generally the updates are not so wide as to affect all or most cores at once.

Link for the Main MiSTer you can swap out: https://github.com/MiSTer-devel/Main_Mi ... r/releases

Maybe one of the unstable builds might help resolve your issue: https://github.com/MiSTer-unstable-nigh ... ble-builds
