Oh, woopsie. I missed that, sorry. :P By the way, thanks for your efforts, your work will greatly help understanding this kind of hardware better and help people out there repairing broken boards.

The QSound amplifier has been retro-engineered, there are just some caps and resistor values missing. https://twitter.com/WydD/status/1335312921228931072 https://gitlab.com/loic.petit/cps2-reverse/-/tree/master/CPB-001A https://petitl.fr/cps2/CPB-001A/ Hopefully this is finally going to put...

Thanks for the kind words :) Just to make it clear: I'm alive and well, other things got a bit sketchy and other priorities came up, that's all :D

Regrettably, I have to ask to be removed from the list.

I feel this really needs a separate thread because the issue at hand is of utter importance since it sets people's expectations on a certain device. All the points made here, to me, are absolutely valid. On one hand, we should definitely try to document and reproduce old (failing) hardware by...

Damn, I'm overwhelmed by the huge wave of common sense in the latest posts. What happened? Besides, FWIW, jotego is using a logic analyzer to study each board to replicate the exact behavior of the various custom chips which have not been decapped/documented yet. While it's not perfect down to...

Because I'm sick and tired of people spreading misinformation which then end up spending money on something thinking that it will just give them the best experience possible without having any knowledge just because someone on the internet said "just buy this used PC for $100, put groovymame and...

Then let me tell you that at that point a raspberry pi is a cheaper option and it's able to output native resolution and correct refresh rates just like GM and it runs everything up to PSX. The whole point it's never been what's cheaper in absolute terms (ie: money), but what's the best...

That's the worst point possible you could've picked to make a GM > MiSTer comparison. It took me almost 1 year to fine tune everything on my GM PC and I was still tinkering after. I think I've spent way more time tinkering than playing on that machine, which is just plain wrong. Let's just say...

I've built as well a dedicated emulation box (mainly GroovyMAME) and still have all the prices of the components I've bought: Intel G3258 (overclocked to 4.8Ghz) – 67,55€ AsRock H81M-G – 42,15€ AMD HD5450 (used) – 20€ Antec VP350P – 23,50€ 4GB RAM (used) – 24€ Small form factor case – 46€ Hard...

Cool, now add a PSU, case, hard disk and RAM and let's see what's the price. Oh, and MiSTer is tiny, so unless you're willing to spend quite a bit for a dedicated small case you'll end up with a big and heavy thing. The irony of all this, is that I'm defending the PC setup while not...

A custom PC build, exclusively made for emulation, where you actually use raw input with a video card capable of true analog out via VGA (you can get both RGBs and RGBHV from it) with a heavily customized windows installation with lots of the useless stuff removed, Windows XP (32-bit) or 2003...

I can't remember if this question was already asked, but how much does a game take to load? CPS1 games are rather small, it should be quite quick.

@wuemura according to your own researches, they *are* wrong (EDIT: to better clarify, "they" is referred to ValleyBell and superctr), because as you can clearly read in ValleyBell's information, the phase shifting is done *in software* and not on an outside board and, again, as stated in the...

for @wuemura and all other people how might be interested in the discussion that arose earlier: I've reached out to ValleyBell asking to shed some light (at least for me) on the QSound situation both regarding MAME and how it works and he has given me permission to copy-paste his reply here:
