Capcom CPS1 "3 Wonders" PCB question...
For those of you fellow arcade PCB hobbyists, I've got a question regarding the CPS1 produced "3 in 1 Wonders" International Bios ver. PCB -- is there a suicide battery mounted to that particular PCB and is there a way to make it "suicide-free" (like the latter produced CPS2-based PCB setup)?
The hand-drawn sprites featured on this particular arcade PCB are still breathtaking today since it's worldwide release in 1991. ^_~
Imagine a Cave "Tate" arcade shmup title with such lavish "hand-drawn" sprites being produced today...would it fare well in today's arcade enviroment or be regaled to the dark & dank recesses of an arcade joint never to see the 'light of day' ever again? (Just a thought to ponder upon...) ^_~

Thanks for the 411 on the CPS1 hardware info...
For footix,
Thanks for the 411 info on the "3 Wonders" PCB...
My "3 Wonders" PCB still has the original battery and still works like a charm in 2006.
I wonder just how long such a CPS1 suicide battery lasts though it was installed at the PCB manufacturing plant back in 1991?

i don't know exactly about these batteries, but cps2 ones are supposed to remain power for 5 years if the boards is in storage (understand not powered up). So i suppose that batteries on cps1 should live approximately the same.
i bet your board has been played A LOT and that the estimated 5 years of non powered up time has not yet ended.

Hope it's okay to resurrect such an old thread, but I'm curious if anyone has resurrected a World version (as opposed to Japanese or US versions) of '3 Wonders' using the unencrypted US set here:

I'm having some graphics problems since modifying a World version of 3 Wonders which didn't have any graphics issues before the battery died. I've modified a fair few CPS1 boards in my time and this is the first one that has given me problems, possibly as a result of trying to use the only available set for the US version on a board which previously used the World version (although I've replaced the other US relevant ROMs too).
Bit of a puzzler.
Thanks

I do get nervous about this from time to time as well. Is there no battery holder you can solder on for CPS1 PCB's, as I've seen someone do for CPS2? This would be a great improvement on battery changing.

Yes, I don't see why you couldn't solder on a battery holder, BUT you would still need a helper battery to provide power while you're removing the original battery and attaching the holder. You'd also need the helper battery for later when swapping out the battery that's now in the holder ........... I suppose you could attach TWO battery holders .............
With 3 Wonders, you HAVE to be careful anyway, as it must be one of the best CPS1 boards. Chariot FTW!R-Typer wrote:True, but a bit risky unless you're damn careful.

Found that the key EPROMs appear to be 29 and 34, , ie the problem EPROMs are AM27C010's used for those binaries (which are rated at 150ns) which cause the graphics and lockup issues previously mentioned.
The solution is to use 27C010's rated at 120ns or faster OR to use, in my case, 150ns EPROMs from different manufacturers (I'm using Mitsubishi and Intel as an experiment). Both work fine.
