The reason I ask is because one of the reason I originally got my c64 back in the 80's was because others had it, and they got it because they could trade games. At the time I did purchase quite a few games (wish I still had them), but also had alot of copies. I think one of the major reasons people are still in the c64 scene is because they can use an emulator (or the real machine since its easy to find and cheap) and play EVERY game out there for free. If you had to pay $20 for each old game today who would do it?
The same goes for the emulators running on the dreamcast and the xbox. The scene for those 2 systems was helped immensly because of the hacked hardware. I guess its the same for every hacked system.
