I am currently trying to figure out what the prefered console would be to run on.

I tried to find example videos with load times of Oklahoma and came to these findings:

1. Xbox (NTSC) ~4s (faster than xbox360)
2. Xbox360 (NTSC) ~4s
3. Wii ?? probably faster than GCN
4. Gamecube (NTSC) ~12s
5. PS2 ~12-15s
6. PS3 ?? probably slower
7. Dolphin (NTSC) ~22s
8. PCSX2 is out since it runs the game above fullspeed

To keep the game as accessible as possible, its best to not allow modifications that go past the original hardware. Softmodding is often allowed as it allows for region unlocks. In that sense the Xbox that already has a built-in HDD can play games from them, which possibly lowers the load times even further.

Tho loading times are not everything. I have the feeling that the dolphin emulator has some quirks that are hopefully not found on consoles (e.g. dropping inputs and such). Also I currently don't know if the NTSC version on PS2 runs at 60fps or 30fps.

If anyone has information, opinions or whatever. Feel free to share it
