Hi to all interested in porting this to other platforms, e.g. C64 :) There's not much I can remember, but GCUBE3.BIN and .DAT are the XM in my own format so you don't need them. GCUBE3.XM is the original track. DEPACK.C also belongs to the player. This time almost all is done in C except the poly-draw routines in POLY.ASM. It was even coded with porting in mind (actually it was written under Linux with a minimal editor written in QT) so it sould be easy to give it a new framebuffer pointer. If you want to know: "G-Cube" stands for "Gravity Cube" since it's a physics simulation with cubes :) Thanks to shash/collapse for porting The Fulcrum. Greetings, Digisnap
