A developer who posts on X as alexfredo87 has shown off an emulation project for the Super Nintendo and Sega Genesis/Mega Drive that uses AI to convert the original sprites into HD artwork.
The author says the process is fully automatic and once a game has been "converted" it can be played in real-time with the new artwork in place of the old ones.
alexfredo87 on X said:I have something special to show today. I’m also working on a Super Nintendo and Sega Genesis emulator that uses AI to convert the old sprites from games on both consoles into HD sprites. Once the conversion is done, the games can be played in HD.
Here’s an example with Ranma ½: Hard Battle on Super Nintendo. For this test, I only converted the background and female Ranma, but I can convert the entire game into HD. The whole process is fully automated and works with all SNES and Genesis games.
That first demo used Ranma ½: Hard Battle on SNES. With further examples showing the SNES version of Mortal Kombat where only a single character sprite was swapped out while the background and her opponent kept their original sprites and a third demo shows Sonic the Hedgehog getting the same treatment.
This is clearly still early work in progress and the developer mentions a bug in Mortal Kombat where the HD sprite sometimes suddenly shrinks randomyl and the Sonic clip has quite a few apparent visual glitches. But the author intends to fix them, describing the project as just a quick proof of concept for now.
Nothing has been said about a release, a name for the emulator or which AI tools are involved/required.
What do you think? Would you want to play classic games in this way?
