MSX playlist has 11. MSX2 has 9. RetroAchievements lists 31 total, however there are a mixture of homebrew, non goodsets, and TOSEC that are required. I only use ROMs from the No-Intro set which is why those have been excluded. RetroAchievements treats MSX as a single platform while No-Intro and LaunchBox have it as two hence the separate playlists. These two are based off of MSX (20221022-011122) and MSX2 (20221022-005429) DATs.
