Sega Genesis/MegaDrive Overclocking Project

Many of you have probably seen this already, but I thought those of you that haven't might find it interesting. A while ago I perfected a method to overclock the Sega Genesis a.k.a. MegaDrive system's 68000 CPU from 7.6 MHz up to 12, 13.4, 14.6, 16.0 and 19.6 MHz.

The more intensive games would make the system actually slow down-- sometimes only a little bit, sometimes massively, sometimes to the point where the games are unplayable. This is what the overclocking fixes. It doesn't make the system run too fast, just prevents the slowdown-- since the 68000 is the only part sped up, not the video or sound chips.

I've documented all my findings, demonstration videos, et cetera on my site, Epic Gaming, here:

.. now that I have a good source of income, I'm planning to buy a low-wattage peltier to put on the 68000, attach a little heatsink/fan, wire up a variable oscillator and try for higher than 20 MHz. Looks like it will work quite well! (If someone wants to donate any equipment to the project though I would not be wholly opposed. ;))

Coming soon: NES overclocking! :)
 
Of the ones I own:

Sonic 1, Sonic 2, Ecco the Dolphin 1/2, Hard Drivin' (3D), F-15 Strike Eagle II, Gunstar Heroes, and Vectorman. Almost all my games. ;)
 
hell yeah, Vectorman use to slow down all the time, especially when there was stuff blowing up and whatnot.

I recall one of the farther levels in the game where you shoot that big dude that sits out all thoes explosives and in the backround you see all these buckets moving and whatnot...

i think that was my 1st expirience of Lagg in my life, LOL :D
 
Must've seemed a bit odd when every game did it the same way, eh? ;) The system is locked to 60 or 50 Hz depending on your region, it ALWAYS draws that # of frames, unlike PC lag where a game will draw 10 out of the 90 or so frames you'd like to see a second. The MegaDrive/Genesis draws the same one over and over while it waits on the CPU to finish doing the math to produce the next one.
