Anyone here build or have one?
I really want to build one, and could use some advice or worthwhile research material

I've got an ancient Dell Dimension with a Pentium 4 2.8ghz processor that I'm thinking of using as fodder

Whew lad that's a pretty old PC to be turning into a MAME cab but it's pretty ideal to turn into a Windows 98 gaming PC. If you're dead set on building a cheap ass mame cab out of it, I'd suggest starting with some kind of narrow shelving unit from Goodwill to hold its monitor which I hope is a VGA CRT up at about five feet high or so. Get a couple sheets of particle board or wafer board and cut them into arcade-cab-shaped sides. This'll be the most important step to making it look nice. Screw 'em into the sides of the shelves, get some plexiglass to make the marquee and monitor bezel then scrounge up some scrap wood to make the front and control panel. Use some cheap Playstation arcade sticks with a blue v shaped USB adapter. If you're going to use an LCD monitor and you want the materials to be even cheaper (just one sheet of wood) you can build a Vigolix. They look pretty good, see pic related. Much more detailed instructions available online, too.

Here's what you do OP:

>remove guts and monitor if it is nonworking
>find a CRT -television- (not monitor!)
>mount in the cab in whatever way ya got to
>install some way to play games that gives you a native resolution (usually 240p) image AND low lag.

Do not give a fuck about muh RGB. It's a rabbit hole you don't want to go down and its not worth it. Do NOT use some kind of candy-ass laggy-ass adapters for your controls.

You want a TV because TV's look better than VGA monitors.

>but what about those Sony PVM people always talk about

If you've got one, use it. If not just fucking forget you ever heard of such a thing. You'll be better off for it.

Real helpful advice there. 640x480@60hz with a simple scanline filter will behave almost identically to 240p which you clearly have zero clue how to get out of a PC since you're saying not to give a fuck about RGB.

OK, for consoles, whatever, there are arguments for using S-vid or composite, but not using RGB for arcade shit is just wrong. I mean, if you simply can't, whatever, but non-vector arcade games are RGB.

Here are some of the pics from when I built mine a few weeks ago, your computer should run it fine, but best bet is to get it all installed and running before you bother with the construction.
I started with 4 Sheets of wood and had them cut at home depot to the larger basic sizes I need for the side since I don't have a table saw or anything at my house, everything else I did with drilling pilot holes and using a jigsaw.

It's kind of a sliding scale depending on what arcade games you want to run. For the hell of it I went ahead and cross referenced the requirements for 1999 arcade games, most notable of which being Naomi games (and Neo Geo but that'll be no problem). OP actually has almost exactly the minimum hardware required to run NullDC hopefully he has an ATI 8500 or better. He'll want ATI if he ever ends up switching to a real arcade monitor but not TOO new. Looks like he's sitting juuuuust about right for /vr/ emulation. Except N64 of course. Nobody can emulate N64 right - not that you'd want to with arcade controls anyway.

RGB on a PC VGA monitor looks terrible and nothing like how arcade games actually looked (even at 240p). A PVM is not much better. A television will have a coarser dot pitch and shadow mask design which will be a lot closer to an "arcade monitor" (unless it is an aperture grille design itself).

At 240p you have enough signal bandwidth that the image quality of S-video vs RGB will be very, very close (provided your source sends a clean signal). Component video will be 99.9% identical to RGB, indistinguishable for practical purposes. Composite is also very good if you have a clean source. The PS2, Gamecube, and Wii all have great composite output.

Overall, I'd prefer a television with a shadow mask and component video over a PVM. That's actually much closer to the True Arcade™ aesthetic. A real, honest-to-god Betson, General Electric, or Wells Gardner CRT would be best tho.

Every consumer television with S-video input made before the HDTV era can accept 240p over the S-video input. All of the Trinitrons, as well as all other models. There's nothing in the S-video spec that prevents.

I used to play an NES emulator on the PS1 called ImbNES that had a very nice 240p image over S-video. Looked 98% as good as RGB. The only difference was you could tell the televisions sharpening and noise reduction filters were introducing a bit of artifacts.

That is categorically wrong. I'm with the other guy, you need to do your research. The Wii in particular is well known for its 240p output since it is one of the easiest paths to a very nice looking retro image with 240p over component video.

And every one of them is putting out an interlaced signal. The game may be 240p, but that's not what comes out of the unit. But whatever, you've clearly never spent one day being a video engineer.

240p is exactly what comes out of the unit. When you tell the CRT to write fields on top of one another you're sending a 240p signal.

Your attempt at getting off on a not-even-correct technicality here is pretty desperate and embarrassing. You repeatedly implied the systems in questions could not output 240p over S-video when they clearly can.

480i with fields writing over one another = 240p and no amount of whining on your part will change that. Otherwise you'd be claiming the freaking NES doesn't output 240p and that is simply preposterous.

>Interlace and computers
>"In the 1970s, computers and home video game systems began using TV sets as display devices. At that point, a 480-line NTSC signal was well beyond the graphics abilities of low cost computers, so these systems used a simplified video signal that made each video field scan directly on top of the previous one, rather than each line between two lines of the previous field. This marked the return of progressive scanning not seen since the 1920s. Since each field became a complete frame on its own, modern terminology would call this 240p on NTSC sets, and 288p on PAL."

is this post for real

mate, you can send 240p over fucking anything, it's basically just adjusting the sync to make the fields overlap (resulting in all displayed lines being updated each frame -- the definition of a progressive signal) instead of making them land on separate lines every frame (read: no interlacing)
each frame, you send 240 lines, in order
it isn't effectively 240p, it is 240p

you can send it over component, s-video, composite, rf, rgb, whatever -- basically, only HDTVs might have trouble (there's a few LCD TVs that won't decode 240p over component, annoying the hell out of a few people who want to play PS1 games on their PS2), no CRT television set should have any trouble displaying 240p
240p display is all in the sync.

maybe this is some shitty effort at trolling, but I already typed all this shit up

>>4019824
every single one of those machines can output 240p

PS2 has it because the vast majority of PS1 games run in 240p.
GC has it, but I can't think of anything that uses it off-hand (weren't there some emulated NES games that used it?).
Wii uses it for Virtual Console (NES, SNES, TG-16, Neo Geo, Genesis, etc). There's a bunch of homebrew emulators that run in 240p, too.

>>4020141
