Hi,

I bought some M27C800 chips in order to make some repros. I don't really understand which pins do I have to wire. I've soldered all the pins except A18. I've burnt a 1MB ROM on my 1024k EPROM, with success. But somewhay the game doesn't boot. I don't even have the Sega license panel.

The donor cartridge contained a 1024k ROM on it. So from what I've understand, I only had to solder all the pins except A18.

Did I miss something ?

Thanks for your help
