The Scud Race one can be accessed by patching the ROM. For those who can build Supermodel, the necessary change would be to Src/Model3/Model3.cpp immediately after line 2943:

Code:


else if (!strcmp(Game->id, "scud"))
{
	*(UINT32 *) &crom[0x799DE8] = 0x00050208;   // debug menu
}

(I haven't actually tested this in ages, though.)

With the patch, attempting to enter the service menu will instead activate the debug menu. To my knowledge, nobody knows whether it's actually possible to activate this code without a patch like this. I believe VF3 also contains a similar menu. It's not nearly as cool as the Naomi one but I think it has a flat-shaded spinning cube or two.
