Advice for a MAME Computer for use with D9200

(1/2) > >>

Hexray2:
My MAME computer was recently stolen :( and I'm looking for advice on what hardware I should be considering for building a new MAME computer.  The computer that was stolen had a Pentium 4 3GHZ and an ATI x600 (or maybe an x300) video card.  It was running Windows 98 SE with Groovymame and was connected to a WG D9200 monitor.  I was very happy with the setup and all the games looked great in their native resolution/video mode.  Luckily, they did not steal the monitor so I just need to replace the computer.

I was hoping to try and re-create something close to my old computer but the hardware is ancient and difficult to find (or very expensive).  Can anyone give some advice on what hardware/operating system would give the best results for Groovymame on a D9200?

I may have been able to answer my own question while reading some other threads on this forum.

I'm currently thinking to build a Windows 7 based PC with an ATI 5450 card with a VGA port.  Something like this:

I'm assuming the video card is really the key component in terms of getting GroovyMame/CRT Emudriver to be able to use proper video modes of the D9200 and that the CPU/RAM/etc won't have an impact.

Does this seem like a reasonable setup?

Well, the CPU and system are what you're running GroovyMAME on, but they don't need to be huge. It's the GPU that's key for video modes and installing  crt_emudriver though, yes.

I would recommend Win10 as being newer and faster in general.

Hi,
a 5450 AMD card it's fine; i recommend you GroovyArcade.

About a year ago I upgraded my 10 year old CRT MAME cabinet which is based around a 27" Wells Gardner D9400. The "right" CPU/GPU combo depends on what you want to emulate. Previously I'd only run GroovyMAME on that cabinet but after the upgrade I wanted to add some other console emulation targets, mostly Sega Genesis / Saturn but possibly a select few PS2 / N64 / DC titles suitable for Arcade cabinet-style play.

Here's the system I went with:

* CPU: i5-4590 CPU @ 3.30GHz / 8GB RAM / SSD + HD / Win10
* GPU: ATI R9 380X OC (factory overclocked version)I bought a used HP ProDesk 600 G1 on Ebay with SSD boot drive and Win10 Pro pre-installed for ~$120 and added an HD I already had for ROM storage. The 380X GPU is the *last* & fastest card ever made with an analog output (which is only on one of the two DVI connectors). They are somewhat rare but I found one for $100 on Ebay, a bit steep for this era of card (2016) but I wanted to get the max possible GPU power to 4x upscale a few 3D PS2 titles to an internal res of 1600 x 1200 for analog display on the D9400 at non-interlaced 800 x 600 @59.94fps  - while keeping that visual retro magic only an analog component signal on a quality multisync RGB CRT can give.

Note: The 4GB RAM R9380x (2016) and the earlier 3GB RAM R9 280x (2014) are nearly identical in performance (2013-2016 was a weird era in Radeon evolution), so those looking for the best analog output card ever made can choose either one. The 280x has the advantage of a wider memory bus (384 bits) but runs hotter, while the 380x (memory bus: 256 bits) has the advantage of the more recent Tonga / GCN 1.2 architecture with texture compression and faster tessellation. This works out to be within a few percent in FPS depending on the game according to reviews published at the time (380x +4% to -2% vs 280x). Also, be aware the similar-sounding 390/390x cards can cause confusion because they were faster than the 380x and 280x but didn't have analog out (despite some product spec listings erroneously saying they had DVI-I, actual photos of their DVI connector reveals they don't have the extra four analog pins and are thus DVI-D (for digital-only vs "DVI-I" for both analog & digital). The 280x and 380x both look like this:



But the 390/390X look like this:
