It's close, but the speed isn't correct for games that are sensitive to it (Super Turbo, Hyper Fighting). The popular CPS2 emulators still have rough CPU timing approximations, as none of them implement the memory access delays of the original hardware. It is all dependent on the driver for a particular game and its hardware. They don't have a single static level of accuracy, advantages, or caveats. I wonder if most failures occured in the late '90s and early 2000s, and if we will see less of them going forwards.Don't forget that emulators are only as good as the code the author wrote. I've come across many failed CPS-A-01 chips, but have only ever watched one transition from working to non-working myself. I'd really like to put together a database of those which have failed, and those which are still working, and record the manufacture dates to look for a pattern. On the flipside, my 100% conjecture take on it is that most of these chemically poisoned CPS-A-01 chips have already passed their half-life, and that most which still work now will still work in ten years. That would mean that running it less often, or with a heatsink, etc. The impression I have gotten from talking with a few others is that this is usually a result of a chemical defect that occured during manufacture, rather than an electrical failure. I will happily give away hacks that I did out of interest or that solve a problem for me and others, but this one is steeped in yawnsville so it's super low priority.Īs for failing CPS1 boards, it is nearly always a problem with CPS-A-01, and next most frequently CPS-B-** on the C board. If I come across another MSTREET bootleg I might do it for some tiny bounty, I dunno. Click to expand.It doesn't exist, but it's probably something that wouldn't take more than a bit of weekend work.
