To the original poster: I realize that this response is about five years late, but hopefully someone can still derive some benefit from it. The only way that I've gotten Classic99 to play nicely with LaunchBox is to: - Add the desired game manually and uncheck "Use an emulator to play this game" - Under the "Launching" tab, browse to the location of your "Classic99.exe" in "Application Path" - Under "Application Command-Line Parameters" enter the following: -rom "path/to/file/ROM NAME.G" You'll notice that the "ROM NAME" example above has a "G" suffix. This is because all of the roms that I've found thus far usually consist of one or two files for each game, with each file being designated C,D,G, etc. What worked for me was to rename each file according to the type of file that it is. For example, downloaded Pole Position for the TI-99/4A. It consisted of two files: "PolePositionC.bin" and "PolePositionG.bin". I found that Classic99 expects the files of a game rom to be named the same, so I renamed those files "PolePosition.C" and "PolePosition.G". Once I did that, LaunchBox was able to load the roms correctly and I could launch any game I wanted from the LaunchBox interface. I hope my instructions were clear enough, and I hope this information is helpful to someone.
