You can always try shorting out the address lines (or data lines) on the RAM, especially if you can get at the VRAM in particular.

I want to get at the VRAM but this console is a pal version of the sega mega drive 2 and in any documentation I can find the VRAM chip looks completely different, in the console I have where the VRAM chip should be there are two chips in its place, any ideas ? I will post up pictures tomorrow when I can get a chance. Sorry if this is all a bit vague

I think I recall the Gen 3 I bent for visuals having two chips for VRAM. I wound up using bend points on both. Just go for it - if you can find a pinout for the chips it will help you avoid the VCC pin, otherwise you can't really hurt much.
I'll try to find the photos of mine that I took while it was still open.

have you seen gijs mega drive stuff yet?

the board in my one looks like this; but i think there were about a billion different revisions. you cant really go wrong if you avoid the Vcc pins, even then its pretty unlikely to fry anything if you just probe on the ram chips and stay away from the power supply.

Yes, this is the VRAM. This should be the pinout:
