As some of you probably know, Nemesis 3 does not work on SVI-738 machines. Since Ramones got a SVI, we examined the game ROM and tried to find the bug.
If a MSX2 computer is detected, the game changes the color palette. But the problem is that in MSX1 models the call to the subrom to change the palette is also done (but there is no subROM entry call in the BIOS!) So it executes a lot of NOPs until the program counter reaches the first piece of code in the BIOS. But in the SVI BIOS there is some code at #15F (subROM entry) that causes the crash.
It seems Konami forgot to check the MSX model before calling to the subROM. So we made a IPS patch to solve the problem.
