Title: Pong Emulated (sort of)
Post by: Tiger-Heli on July 13, 2005, 07:39:57 am

Thought this was pretty cool:

Note-this isn't what MAME was doing a couple years ago, this is actually modeling the circuits to  produce the screen actions.

Now that is cool. I fully intend to play with that later. PONG! (well Rebound, but yea...)

Wow. Not just pong either. This thing emulates a handful of games, including frogger. And if I'm understanding the emulation correctly this sounds like it's held "truer" to the MAME spirit of documentation - since it's emulating individual circuits at, what seems like, a lower level. Can anyone verify?

Yes it's low level circuitry.  What we need to do is point this guy to the descrete logic page and hopefully he can use the schematics there to simulate more games. 


In the case of the rom-based games though, this is considered overkill in terms of the emulation.  It doesn't really make anything more accurate, it'd just require more resources to run.

Bad news..... I just tried it and it runs at about 3 fps on my Athlon Xp 2600. 

It makes the slower mame games seem fast in comparison.  My guess is the hsync and vsync circuit translators need work.  Turning analog goop into a digital picture has got to be complicated.

yup.  super slow... but cool non the less.

Yeah.... considering it's really the only way to emulate descrete logic games, I'd say that it's a project worthy of being kept up. 

I just find it ironic that, if the code is left unchanged, we'll probably see San Fran Rush playble on our cabients before we see pong.  ;)
