Is it possible to emulate the Dreamcast/PSX 2/Dolphin?
The Dreamcast is quite easy to emulate since most of its components are “off the shelf” and heavily documented. Still don’t expect anything even remotely useable in the 2nd millenium (yes, I mean ’till 2001). Getting the games into the PC may however be quite difficult since the Dreamcast uses a quite weird CD-Format to keep software pirates from burning copies. This also makes it impossible to read Dreamcast CDs on normal CD-ROM/DVD drives. The same is true for both the PSX 2 and the Nintendo Dolphin. Also, the PSX 2 and the Dolphin are mostly hot air by now. There isn’t much knowledge about which parts are going to be in these consoles, so it’s hard to speculate how easy it will be to emulate them on a PC.
