Megadrive 2 Modding

[Cyber Axe]

hi just wondering about a couple of things about the mod as the guide doesnt mention them

firstly does the pin 107 have to be lifted from the pcb?

secondly does anyone know if the 315-5660 is a safe chip to do the mod with (since the guide says some chips will fail) its a PAL MD2

That chip is safe to use, it's the same as mine, also a PAL MD2.
As for leg 107, it has to be disconnected from the rest of the circuitry somehow. You could cut the trace running to it if you don't want to lift.

I just cut the trace from where it ends up (a VCC point) and soldered a wire on it.
