The two roms would be transformers decepticons v1.1 and transformers autobots v.1.1. They are basically the same game, but they are two different versions. For my DSTwo, There is a black flickering at the top of the screen every now and then. Its quite annoying. If anyone here has a DSTwo, try the roms and see what happens. Here are the downloads (they include my DSTwo compatible save files as well) I dumped both the roms and save files from real game carts, just for info.
