Prince of Persia was originally released by Broderbund for the Apple II computer in 1989 and went on to become a successful franchise containing sequels, spin-offs, a movie, and various other pieces of media.
In the past, the original has been ported over to a bunch of different platforms but the Commodore Plus/4 has somewhat understandably never been on this list of machines due to it being discontinued in 1985 (four years before the game's release). For the longest time, the closest we got was an unofficial fanmade demo in 2007 from Guys From West and Absence and Wilds that featured monochrome graphics and just 5 screens, but this was eventually discontinued for unspecified reasons.
This new port allows you to play the game from start to finish and features a much more diverse color palette than the earlier attempt.
You can download it here if you're interested in giving it a spin.
