I've heard that the structure of Game Gear and Master System games are fairly identical. When it comes to building my rom library, however, this can get frustrating. Games that should be in the Game Gear folder go over to the Master System folder, even though there is already a Master System version of the game.

This has happened for me with:
Dizzy games
Predator 2
Outrun Europa
Rastan Saga
more

Rastan Saga is strange, in particular, because I was able to find a .gg version, but half of the screen is cut off when I boot it up. I've also tried using a hex editor to export in the appropriate format, but this doesn't work.

Do any of you know where the proper .gg versions might possibly exist? (Megathread files are .sms)
