Discuss modifications you have done or plan to do to your Dreamcast or any other hardware, or discuss devices you want to build. If your console does not work or is acting up, ask about fixing it in here.
like mentioned on the site. homebrew (especially emulators) will be helped quite a bit. the guy mentioned on the site that his divx movies and DreamSNES both sped up somewhat. even some of the original commercial games that lagged a bit sped up.
Wait, i'm confused... Where do I pull the 40Mhx signal from? The guide doesn't say... i can't pull the 54Mhz signal fromthe graphics CPU or it will definatly run HOT, or break! Where is the 40 Mhz at?
Why doesn't HTML work anymore on this damn forum!? God!
It's on the clock chip, 3rd pin down. The 1st pin is the graphics clock. You have to pull the 40 mhz signal from what I presume to be another clock, not on the DC.
I know this isn't the case quite so much any more, what in this modern age of lazy ports and easily-converted PC sourcebase (glares at many companies that have done obviously sloppy jobs in porting their work to GameCube), but don't a lot of commercial games rely on a console having predictable, "closed" specs for timing/sync issues? Wouldn't fiddling with those specs break compatibility with a lot of official releases?

yes. very much so. the idea though would be to have a compatability switch so that games not working with the overclock can be run correctly.

You have to buy a 40Mhz Quartz Crystal Resonator and attatch that to the third pin on the clock chip.

The easiest way would be to solder a switch to the 3rd pin of the graphics chip and to the quartz. ON = 40 Mhz quartz (ie:
240Mhz) OFF = 3rd pin of graphics chip (ie: 200Mhz)
but seriously, good luck. maybe if this becomes more mainstream and easy to do (maybe a modchip of some sort?) we could see some more homebrew that we couldnt before because of cpu limits.
i saw this site like 6 months ago but i would of thought you guys would have known about it already.
I was stupid enough to keep putting a warez link into my sig.. even after an admin removed it.. twice... I'm such a bloody moron. Oh well.. and now i'm banned too. boo hoo.
