i took your suggestion but i haven't played it yet :o someday
today i did an overclock on a sega genesis, upping its 7mhz clock to a massive 10mhz. it's a little scarier than the usual mod cause you have to lift a leg on the cpu, but the mc68000 has some pretty big legs compared to the average modern ic so it's only kind of scary. don't mess up though. also this cpu is pretty overclock friendly, you're fairly safe to give it a little boost to cut out some slowdown without making anything act up.
i didn't even think to take a picture til i got way into it. i have a 10mhz oscillator mounted on some perfboard and all the frightening stuff is already over with
and skipping ahead a bit more i have the whole mess wrapped up in electrical tape and wired up to a dpdt. the other pole goes to a red/green led whose color will give you a hint as to what clockspeed the cpu is running at. being able to return it to its normal setting is important also since the 32x and segacd will not function properly on an overclocked cpu. i don't know if the power base converter works with it cause i don't have one :<
the switch honestly doesn't look all that great :< the sheetmetal screws holding it in dont help much either. but it's all i had on me forgive me somehow
so when i was about ready to start testing it out i realized that i don't have any kind of video output cord for a genesis which is kind of silly. i do have some 8pin din plugs though so i made one on the spot. looks great i know.
and there you have it :o subterranian action at a blistering hyperspeed.
if i have some time tomorrow i'll try to do a comparison video
