GameCube, PS1, PS2, PS3, Xbox 360, Dreamcast, GBA, PSP, NES, MAME, N64, Megadrive, Wii, Game Boy etc. One console to rule them all. :-)
It just works like any normal Xbox, all your normal games etc work. You just reboot into Developer mode to play.
See the video above of Twin Snakes running on Dolphin. The price is not cheap, but these are not quick nor easy to provide in such a good plug and play state. Worth the extra, and it's still an Xbox Series S with 2.5TB of SSD storage as well. Two in one for the price of a standard PS5.
If you have an Xbox and everything set up, or want to do it yourself, I can provide the drive with everything configured and all the correct permissions. Just contact me for a quote.
Zero customs fees. The items are already in the EU and the UK (N Ireland). You only pay what you see on the listing.
