For anyone who hadn't seen it yet, I thought I'd post a link to my guide on MegaDrive/Genesis overclocking. There are also quite a few videos demonstrating the results.
The maximum achieved speed so far over the 7.6 MHz Stock frequency is 22.6 MHz. I am working on stepping things up a notch soon with supercooling equipment, so I'll have a new page for that then. In the meantime I hope you guys like this.
Yes. The video's up there too. A friend of mine was awesome enough to digitize it and encode it to DivX for me while I was on. Shout-out to TailChao if he hangs out here.
