admiralj - #1 - no,
#2 - If you are running the game by selecting the CUE file on XBox, then you don't need to worry about a naming convention (provided the names in the CUE sheet match the actual ISO/MP3 file names. If you run the game by selecting the ISO file, then you need to follow the Gens naming convention which is described in the Gens.txt file available in the Windows version.
#3 - Don't know - if you think it is, then turn it off.
Loafer - I shall think about it.
bubbathemaster - I don't think save/load states as a selection from the Options menu is preferable to doing it in-game. People generally prefer instant loading/saving of the games. Also, you are not forcing throttle when you save/load state. Throttling is *RIGHT* trigger, state saving/loading uses *LEFT* trigger.
XDelusion - I did not change anything in the code wrt CD-emulation other than the alternate starting method. However, I tried Dune using both methods and it played exactly the same for me either way. You need to be more specific about what exactly was not working. Are you using the alternate starting method? (RTHUMB) What video was not working correctly for you? What is the easiest way for me to get to that video in the game?
