What is Nucleus?

i hope he fixes everything on his rsx branch, for some reason, all psgl samples render offscreen and gcm samples are broken, only cube samples work, other have rendering issues.

i just can't compile his "rsx" thread

i got message "internal compiler error"
(Correct: An internal error in the file compiler)

You shouldn't expect rsx branch to work. It's DH's development branch and you should expect it to not work.
