  1. For those who don't know, Heavyweight Champ is a 1976 boxing game released by Sega and is considered to be the first fighting game ever made, but unfortunately it didn't do to well in the arcades and fell into obscurity when the 1987 remake came out. All that exists of the game now is a Japanese game flyer and a recent picture of a cabinet which sadly looks like this:post-65196-0-79365000-1552102406.png

     

    Do any of you guy and gals on Atariage know about this or by some chance have any memories of this game?

     

    EDIT: I forgot to add the lost media wiki post [url="https://www.lostmediawiki.com/Heavyweight_Champ_(lost_SEGA_arcade_boxing_game;_1976)"

  2. Which version?

     

    I know senntient.com had some of the developer art at one time: https://web.archive.org/web/20090221025535/http://www.senntient.com/projects/xtreme/sxc The website re-directs to a card game site today.

     

    Ah-ha! An early copy has been released, but it only works on newer PCs: http://www.tssznews.com/2015/02/23/playable-build-of-sonic-x-treme-out-now/

     

    Someone got it to work on the Saturn: http://www.retrocollect.com/News/unreleased-sonic-xtreme-now-playable-on-sega-saturn.html

    Thanks for the links my man :-)

  3. QUICK UPDATE

     

    I've decided to boost my "Deadline" for getting these pong systems to there 50th anniversary due to money problems getting into the way of things, I think I'll be able to get the cheap ones like video pinball and super pong by the end of the year and the expensive and rare ones throughout next couple of years. I'll be posting updates and questions on the pong consoles on this thread so stay tuned.

  4. Fun fact, the pong consoles that used "rainbow" gradients had their timing crystals deliberately skewed slightly off from standard ntsc color frequency. They imparted a square wave overlay on top of the video signal which caused a "rainbow" effect on color tvs. Since the offset of the wave determines the color hue produced onscreen, the fact it did not match the timing crystal inside the tv caused a gradual color change from one side of the screen to the other.

     

    I would imagine most modern hdtv flat panels would not process this off spec colorburst signal correctly. You may end up with fine pitch grayscale jailbars if you get anything at all. My 4k TCL hdtv did this when I loaded Air Raid from my Harmony cart (possibly it expected a PAL colorburst? Air Raid has way too many scanlines, 290, such that many ntsc tube tvs without a vhold adjustment will actually screen roll).

    Cool! I didn't know that!

  5. There's no way AC can leak inductively down the 7805. And no way to get 125V DC from a 9V/1A AC adapter.

     

    Did you mean 5V DC after the 7805 and 125V AC from the mains? If so, then the main step is to check the solders and reseat the 6507, RIOT and TIA. Use an antistatic wristband or at least periodically ground yourself before / while handling the circuit.

    yes
