Both versions (original + Special Edition) were among the first games I installed on the Deck when I got it, and habe stayed installed for years since. I still go back and play one or the other a bit every couple months.

The only issue I can remember is just dealing with the stupid launcher screen before you get into the actual title screen. I think I might have had to change the launch options for one of them to be able to access the graphics settings?

Interestingly, the original version is still listed as Playable even though tbr Special Edition is Unsupported.
