Sell it as a "circuit bent/glitched" Mega Drive on eBay, make $$ billz, buy a working one and send me what profit you've made as a fee.

However, now the audio's being tempermental. YAAAAY.

At some points on all of my games, the audio will come in late or early.
For example, when I start up my Sonic 3 cart, the "SEEEGAAA" voice comes in late and has the S chopped off.
Level music starts late, and sometimes gets cut off at the same spots.

This happens with all my games.

Any ideas?

Perhaps it's the pins are not making contact with the cartridge properly e.g. Grime.

However it seems to only work when it wants to - which isn't very often.

When it first started up my old one, the TV would show static until you switched it on (which I'm 99.999% sure is normal).
Now whenever I switch this new one on, there isn't any static on the TV.
The screen stays black as if here is nothing connected. Audio doesn't come out either.

Is this a common problem? Can anybody help?
