Awesome stuff going on here! Been having it play in the background with stuff and I dig the presentation, though I do have two things to point out:
- Some of the games are using the wrong soundtracks, as in they have soundtracks from their sequels rather than the games themselves. So far I found this affects Battle Mania, Columns, Lemmings, Puyo Puyo and ToeJam & Earl.
- Some games that got physical Japanese releases are strangely missing altogether, the most notable one being Sonic. If you're looking for Sonic covers, then Sega Retro has a sister site called Sonic Retro that you can source the covers from.
