The resolution option I have available in MAME is actually 256x288, not the other way around...
Sorry, this:
Anyhow, MAME's output of "288x256" IS displaying correctly...
is a typo, it should read:
Anyhow, MAME's output of "256x288" IS displaying correctly because it's really putting out 288x256, you just need to rotate the game with the tab menu so it will fit.
See what I mean? Everything's already set up correctly for a vertical monitor. Before you make changes, try adjusting the rotation with the TAB menu to check. I edited that post now to fix the mistake.
A mere 2 (or god, has it been 3?) months ago I was expecting to use the S-Video out into an RCA input on any old TV I found. What a fool I was!
I was completely ignorant to all of this stuff a few years ago. I was going to put a computer monitor in a recycled shelving unit with X-arcade controls. A prime candidate for CRAPMAME. btw, what are you using for controls? After learning about Sanwa sticks and buttons, and ergonomic curved button layouts, I had the same "what was I thinking" feeling about American controls and straight button layouts.
That's kind of an inspiring back story there. You should put that in your project thread.
I also had limited arcade experience as a kid. My memories of Turtles in Time are from the Super Nintendo version. I've always been a gamer, but I discovered arcade games through MAME in college a few years ago, and the arcade influence has refined my gaming taste significantly. Although I still like adventure games, like Zelda or Landstalker, and JRPG's, like Final Fantasy or Suikoden, I focused my interest a lot more on "physically complex and challenging games;" 2D fighters like Street Fighter and Blazblue, shmups like R-Type and Dodonpachi, and 2D platformers like Castlevania IV and Rocket Knight Adventures.
Obviously the arcade version of the original TMNT is the best out of any console, but as for Turtles in Time did you know the SNES version has extra levels and bosses and things like that? If you only have one or two players, it could be considering the better version, but for three of four you need the arcade. I'll just support both on my cab
my 8500gt has a 7pin tv out. Im not sure where i picked up the breakout cable but it splits the tv out to rgb hook up. like the one in the link but instead of the vga plug it has a 7pin svideo plug on it. i use it to hook the pc to the tv.
...
Seems i had a compatible card looking me right in the face. i have a 7300gs pci-e sitting on my desk right by my monitor.
Yeah, I'm still a little confused about this "RGB" breakout cable, you're plugging this straight to the TV? You said the TV has component input. Component and RGB are equivalent in quality, but communicate colorspace differently, you can't plug one into the other. You'll get a discolored picture at best. Unless you live in, or imported a TV from Europe, I'm going to say that's not an RGB cable, you're getting component out of that port.
I would guess that you can't get progressive 15kHz out of that port, but you should test it out with Soft15kHz to be sure. If you can you don't need the transcoder. If you can't, then yes the PCI-e GeForce 7300GS will work great with a transcoder, that's exactly what I'm using.
