All duly noted on final fights
Lets see how it all goes. Thats a good point about the cps a boards, getting harder to come by now.
While I thought my day off would be messing around playing games, ive spent more time testing stuff. Has to be done I suppose!
Booted up raiden, 100%. The only surprise was that it was raiden 2. No big deal, great game either way
Airbuster has driven me up the wall, still getting scrambled graphics after fiddling with power supply and cleaning and reseating chips etc. Its so close, but its getting put on the long finger now.
Rtype I didn't bother washing/cleaning so much. Got most of the dubious looking grime off it. After airbuster, I was pleasantly surprised to find it fully playable and sound/music 100% (great music!). But the graphics are garbled, got to the end level boss, cool stuff. This one can definitely be rescued (not so sure on airbuster).
I'll clean rtype and inspect then that's that for today

It's sad really, one of the best arcade systems of all time and they seem to be dying
I've two working ones that I've to interchange games between as my other A boards have packed it in.
I've had my own theory on this for years and yes while we are losing some A boards to being old and that ,I reckon a lot of the cps1 boards led a hard live, handled poorly and thrown about a bit. I remember seeing an op way back taking a sf2 pcb out of a cab and pretty much lashing it about the place and i wouldn't say that was unique in how most of these where handled.0 -
just received a cool little test/review version of a device Porchy of jammarcade.net is making.
It's PAD dumper and writer too. Plugs in directly onto an arduino mega and he's made the software to allow to dump those annoying PAL chips. They are rarely included in the mame romsets and so far the only limited archive has been jammarcade.

Looks like a wide DIL package though ? Looks a pretty handy project
I've been mucking about this one with mixed results. Having something to plug onto an ardunio would certainly be handier !!!0 -

where can you but them, I take it there is an adapter to use the more common 20pin chips or its on the reverse of the board?0 -

It's that CPS-A-01 Asic chip on the A board that fails. This one in particular has a high failure rate nowadays (exact cause is uncertain, but it could well be corrosion, heat, delamination...etc) Those custom chips were a great idea at the time since they encapsulated a lot of function (in this case scrolling, layers, palettes and related memory transfers ... ) but since no replacement are made , once they fail, the only way to replace them is to scavenge them from another board.
a single chip FPGA replacement hasn't been an option so far due to pin compatibility (not to mention the soldering part and prohibitive cost)
Ultimately, most boards with customs SMD chips like these are doomed to fail at some point, I got a few boards with custom ics over the years but I stay well away from them nowadays as they're a pricey time bomb 0 -
Yeah, as said I said their handling and life in general is one of the reasons I theorise the a chip has succumbed to failure, but again only a theoryand at this stage in their life would be very hard to prove.
I thought I say a boot at one point of pang 3 or the like that may have had cps A chip, that i think might have been a suitable replacement but I think I may have given it away a few years ago as when I had suitable A board to try a swap.... (Not that was confident of doing it
) I didn't have it anymore. 0 -

Neighbour was good enough to hand me my parcel this evening, had forgotten about these
Burning rangers was a great game back in the day (pushed the blockiness to the limit though!) and has a fantastic intro. Frankenstein is a real oddity, im not expecting much, but Tim Curry hamming it up to the 9's cant be all bad :P
Picture isn't the best but theyre minty mc mintington. Just do it, just burning raangEEERRRSSS!

I hate desert strike.
It was the first game I ever rented. I hardly played it because my dad got addicted. He was swearing so much at the game that my mam banned us from renting games ever again.
Still love the series despite that!

I would love to get myself a copy of burning rangers but it ain't cheap. In the meantime I just got myself a PC Engine Core Grafx. Pics coming soon!0 -
