Serious question: What's your setup for that mame rig?
I got it years ago from a friend. When I say years.. It had a AGP Ultimarc video card in there, circa 2003 or so connected to a PS2 JPAC converter.
Nothing special on the upgrade. Just a $20 Dell Nostro 230 (3ghz core 2 duo) that I picked up from a local thrift shop. Video card is an ASUS ATI5450. 64gb SSD and 3 gigs of ram. Had to install CRT EMU Driver to get it to work with the arcade monitor. I tried installing Groovyarcade linux distro on it, but oddly enough some games didn't work right (Super Contra ran hella slower than it should have) Frameskip made it skip too many frames. Right now I'm copying over Hyperspin.
