groovymame x real hardware

[stellarola]

Don't mind the vertical/horizontal setup.

Pretty damn impressive...

Since ive had GM ive not had a PCB in my cab.. I really love it TBH

[Rossyra]

It is great.

Here's another example - Metal Slug 2. Even the known slow down in the game is emulated brilliantly.

This is an experimental version of GroovyMAME running with ASIO support. Audio is running simultaneously on the neo (mono) and groovymame pc (stereo).

50% odds. I'll take the challenge.

Samurai Shodown - Left is real hardware.
Metal Slug - Right is real hardware.

Awesome none the less! I intend on doing a blind test on myself. If I'm at 100% accuracy then I'll either be buying a lot of hardware or emulating a lot more!

Hats of to the MAME, GroovyMAME teams and ROM dumpers out there.

Metal slug: Right one is 0.027% faster because it is groovymame.

[DaveyD]

Left is real. Right is emulated

So I have a test... Interested ?

Espgaluda PCB vs Espgaluda Groovymame on a lowly PC (c2duo dell thing)

Slight colour differences apart (one monitor chassis has a broken pot for one of the screen adjusts...)

Which.... is real, and which is Groovymame ?




This video is a little confusing. Please ignore all the Gradius III snes chiptunes lol, it was running on another cab to the right of view....

[lacanian]

Left is real hardware.

When do we see the results?

[colinmac]

Nope - left is GM!

Tricky eh ?

[lacanian]

It's so hard to tell with videos.

Can you notice any difference when your looking at it?

[colinmac]

I don't think so - the graphics and screenmodes / scanlines etc are identical, as Groovymame can sort the exact PCB screen mode out.

PC version sounds better oddly, but that's down to a 2.1 sub sound system in the bowels of the cab, vs the normal smallish cab speakers for the PCB.

I think even seasoned PCB diehards would struggle to tell, if I could disable the jpac extra controls (ie credit and escape) !

The sound on the emulated one isn't quite right, that's about it.

It's been a while since I've revisited this thread. Honestly I can't recall which was running which. However, it's somewhat difficult to sync the games at EXACTLY the same time...real hardware or not.

I'm still stoked on my GroovyMAME setup tho. It's a perfect fit for my lifestyle. I don't mind skipping the entire PCB collector bit nowadays. GroovyMAME gives me the same satisfaction without inflated pricing. With the *right* setup it's practially indistinguishable from original.

I still buy PCBs, but it's for games that are not properly emulated. For example, Die Hard Arcade, Aliens (Konami), Mr Driller G.

For everything else tho, it's truly amazing.

Oh ffs!

I'm pretty sure I'm right though. Although it's possible that the selected NeoGeo modeline differs from the one I found with Google.

I bet. You did a great job. The video is perfectly in sync at the start. It does pick up a 1-frame imbalance after a few thousand frames - which is in line with the near-match NeoGeo modeline that Groovymame has to use. If you let it run an hour that'd increase to about second. This is probably the only way to tell the difference - which, being barely distinguishable even side-by-side, is testament to the emulation.

I was told that MAME keeps in sync better than actual arcade hardware. Not sure if this is true or not. I think he was saying that the real hardware has its own drops and that it is normal. While MAME keeps in sync much better, however is not accurate as far as those drops.
