OK, I deleted the copy of coinops and installed a different one I d/l'ed. This time it worked, but still have a few questions:
1) I only installed 4 arcade games - for 2 of them (games the d/l came with) I added the files to the rom, video and screenshot directory, and one game (from my previous roms) I only installed into the roms directory. Well, the 3 games that came with the d/l were listed on the main menu but my old-rom game did not show up??? Also of the 3 games that were on the list, only one had a video of the game while the other 2 had blanks when you scroll to them. What am I doing wrong.
2) still want to know how to make aor buy a trackball.
Oh, I forgot one other question.
If I have more than one arcade emulator (ie. mameox, coinops, final burn, etc), can I save my roms in one location where all these emulators can see and play them?? When going into the settings for coinops I found where to change the rom directories, but they all showed " d:/roms". From what I understand the D directory is a system thing since really the files are on F:\emulators\coinops\roms. But if it is a system thing, how do I make it point to a generic location where all my emulators can see the same roms.
