Howdy folks, here goes:
Track and Field - wont save scores, checked DIPs - buggered - so replaced, same problem. checked battery - buggered - so replaced, same problem. Anything else I can swap to try a fix, or am I barking up the wrong tree entirely.
Altered Beast - No Sound, wont coinup. My Shinobi Board works on the same loom, but swapping the eprom boards still gives no sound. I remember something about a sound hack a while back. would this work, and can anyone supply the necessary part(s).
Hypersports - Sprite colour OK, but backgrounds wrong colour, sometimes snaps back to OK colours, but only about 10 mins every 2 hrs (thermal?). corrupt graphics at boot, but it took months to get it to boot at all, so I'll forgive it for that
Cosmic Avenger - Wont coinup, all other buttons OK. Grounds all tied OK (Pins 1,2 and 26-28) should I GND unused Pins? sometimes gives you 1 credit after about 15 mins from boot when you press the service switch.
Mortal Combat (Bootleg - Yawdim) anyone got the DIPs for it, seems to be set on Insanely difficult, or am I just crap at it.
My PSU gives +5v , -4.5v +11.2v and -13v (ex PC nasty bit of work) could this be the root of any of this, my other boards seem happy with it.
Many thanks
Rick (grobda on ebay, if anyone fins themselves bidding against me, mail me
PS - Mr Welburn et al seem to be doing people a favour - the more choices for buying stuff the better, and where are the laws agains enterprise? If you disagree with someones prices, show me a lower one and I'll probably buy something off you!
PPS - If anyone wants to take these on (bar the Konami boards) I'd be up for swaping them.
