# G-Diffuser: a PC port of F-Zero X and its 64DD Expansion Kit

> G-Diffuser is a PC port of F-Zero X with the 64DD Expansion Kit. It requires a big-endian US revision 0 ROM, a .z64 file. Setup looks for baserom.us.rev0.z64 beside the executable. It also requires the Expansion Kit disk baserom.translated.ek.ndd or baserom.jp.ek.ndd, and a 64DD IPL ROM named N64DDIPLROM.n64 or 64DD_IPL_US_MJR.n64. F1 opens the enhancement menu. The release includes gdiffuser.o2r, which holds the Fast3D shaders used to start the renderer.
