Dreamcast Emulator for Wii (NullDC) - Source code available !

[Xale00]

I suceeded reaching out by mail the dev that did that NullDC emulator port years ago (there a video on youtube that got taken down)

Code can be grabbed here : (check the wii folder)

https://github.com/skmp/nullDCe

I guess it needs DevkitPowerPC to compile (I don't have the environment set up to do it and i'm a noob) :

https://wiibrew.org/wiki/DevkitPPC

I'm curious to see the performance... in fact I just want to see if chuchurocket can pass. Even 50hz version is ok. We got Saturn emulator even if it's bad, so why not Dreamcast after all !

Has somebody here the experience of compiling on wii ?
