SNES Super FX overclocking

SuperFX

marshallh from the benheck.com forums has managed to overclock a Super FX chip. The Super FX was an extra graphics processor included in some Super Nintendo games. Using this chip, games like Star Fox were able to handle polygons and intensive sprite scaling. marshallh removed the 21.4Mhz ceramic resonator from a Vortex cartridge and replaced it with a 24Mhz oscillator and a couple caps. The result is a smoother frame rate and minimal slow down with multiple enemies.

    hackaday needs a copyright or something so you can take action against digg and such.

    Hmm… Better install liquid cooling before they try for 30mhz.

    Hi all,

    I am the one who submitted this story to digg, sometimes i cant directly link to hack-a-day for the reason that diggers do not like undirect links but i always mention in the comment that the story was from hack-a-day and posting a back link to hack-a-day.

    But still most of the stories i submit from hack-a-day i link them directly to you, you may ask why? well cuz i know hack-a-day founder/admin are diggers them selfs and they them self post links on hack-a-day poniting out clearly that they were from digg, but most importantly is giving credit back to you guys.

    i will show you some hack-a-day diggs of mine.

    There are much more but its hard to get them all since i have more then 2000 stories.

    I am much of a fan of hack-a-day then maybe hack-a-day itself.

    You have to also understand my position as a digger, we have a list called “top diggers” i happen to be #1 on that list which i wish it will be removed some day, i have a huge burden on my shoulders in the stories i submit in the content i submit, i am 28 years old and digg for me is a passion, its like loving a women you never met (if you know what i mean).

    I hope you understand my point and forgive me for my wrongs.

    in life we say live on, on digg we say digg on!

    -Al

    then just stop it…

    You sound like a person on th Dr. Phil show.

    Seriously – post an indirect link, don’t just copy the content from Hackaday. So DIGGers don’t like indirect links, so what? Their outrage at an indirect link doesn’t excuse you for violating the Hackaday submitter’s copyright. If you want to give the DIGGers a direct link to the article, then write your own summary.

    If posting to DIGG is such a big part of your life, learn to do it correctly.

    As for the SuperFX chip overclock – that seriously rocks. I can’t wait to dig my snes out of storage and see if this can be duplicated on a Starfox cartridge.

    As the site says, it can’t be done on starfox because it uses a different chip with the clock integrated rather than on-board.

    Um, that was probably a overclock NES. This is an overclocked cartridge for SNES.

    Interesting concept, however, I have since one upped that! I have overclocked the FX chip in “Dirt Trax FX” from the traditional 21.4 MHz to 40 MHz… Imagine that! Works great too. For pics e-mail me at (djblackbox@yahoo.com) By the way, Super NES rox!
