Gameboy Color extreme overclocking

Check out this site where it’ll show you a cool trick that actually TRIPLES your PC’s performance!
The Ultimate CPU Overclocking Guide!

Costis is screwing around with the clock on a GBC and I just couldnt keep myself from trying it out. He quoted some pretty insane max clock speed and I wanted to see whether it would really go that high. Turns out it goes pretty high: ~24Mhz (~3x) for GBC games, and ~48Mhz (~6x) (!) for GB games. Normal speed is 8.338Mhz input, though GB games internally run at half speed (~4Mhz), which is why they can run much faster. This is just a GBC hooked up to a frequency generator implemented on a Spartan-3E starter kit. No extra mods were done to the GBC. I plugged in my desktop speakers to the audio jack so you can hear it better. The BIOS ROM can actually run at over 70Mhz but the screen glitches up pretty weirdly and my setup is too crappy to make it stable. At those speeds the drive strength on the FPGA and other details start to become much more important. Costis work: www.its.caltech.edu Improved frequency generator for S3EBOARD: marcansoft.com

    @595o Ehm, no it isn’t. This is possible, people do it all the time. If it really was fake, too, you would’ve noticed the rest of the video slow down severely when he slowed down the clock speed at 00:58

    so if it freezes at 23 gHz will it blow up at 100? o.O

    @MagneticProductions1 or better yet.. you could buy a new gameboy :]

    the used and barely scratched ones are getting sold on e-bay for less than £10. I got mine from there as i lost my old pokemon edition one and the one i got costed me £9.50 which had no scraches on it and came with super mario land free. so i’m happy :]

    is there any wayyou could fit a rotary witch lik that to the actual gbc? this is what ive wanted to do for ages, as having a switch that you have to turn the console off to turn on is annoying :(

    but it all-so briked at 47mhz not bad

    lol so it bricks if you go over 23.7mhz, still not a bad overclock.

    I found it funny how you started moving/working faster as the game got faster. The human mind is a powerful thing. :P

    Anyways, nice shtuff.
