What consoles output RGB without modding?

My Famicom AV doesn't have RGB and I can't into soldering. My PC Engine, Super Famicom, Mega Drive, Saturn, Dreamcast, PSX, PS2 all use it though!

>>3202

Everything except NES/PC Engine/N64.Why did you sage the thread?

>>3192

Ain't got a fucking display with RGB inputs.

>>3219

Because I was asking a direct question that would not neccessarily be interesting to other users.

Just like this is a direct response that nobody cares about except the user responded to.

It would be rude to bump it to the top of the board.

Knock that shit off. It's only rude if you're bumping shit threads to hide other content.

Component transcoders are your friend.

>>3299

Yeah, but then I have to get a nice CRT, and that's a pain in the ass in my state.

>>3314

Extremely. This is a bottomless rabbit hole.

I live in Europe and our first system was a modulator-less Atari ST, so we've been using RGB as the default basically forever and screaming in pain when forced to use Composite or, god forbid, RF.

PSX and PS2 games using RGB were awesomesauce. Composite dot crawl when having to use a cheaper cable was pretty rank.

At least, with the older TVs that was the case. Modern ones do SO much of a better job with 3D comb filters and the like that I can only definitely tell a difference with fine text (esp that with coloured text overlaying a background of essentially the same luma, or white-on-black at just the right font pitch to induce chromatic abberation type effects) or the most extreme of complementary colour borders. Certainly for most videos and most low-rez games it doesn't make a significant difference any more, so if I get a system that outputs composite I just RCA that shit up and forget about it.

RGB is still good for hooking up to old CRTs, mind.

I want to fit a vga 15 pin connector to my playstation and then use a vga→5bnc cable to connect to a pvm.

I have a question about how to handle the sync. Should I tap the sync directly as this page says: http://www.gamesx.com/wiki/doku.php?id=av:playstation_1_sync

or should I use a sync stripper circuit as here >>3337?

My main concern is whether tapping sync from the board without buffering can cause damage to either the playstation or monitor.

>>3375

Depending on whether the PVM in question actually NEEDS composite sync or not, you could just use c-vid or luma for sync. If your model is fine syncing with luma(Y) or composite video, you can just jump a wire from the multi-out to the H-sync pin of the VGA connector.

I believe the RGB lines of the PS1 have a DC offset, so you'll want to have some 220uf caps installed inside the system on those lines.

Even that is sort of optional in an operational point of view(I've ran Gene- Mega Drives with just resistors in line and it gives a proper picture) but you shouldn't run it for very long like that; It's best not to send extra voltage where it isn't wanted.

The linked sync stripper circuit is only necessary for arcade monitors and stuff that needs horizontal and vertical sync to be fed separately. PVMs at the very most might only want clean c-sync, and that really only applies for older sets and some BVMs. Just about anything from the mid-90's on is fine with composite video or luma int it's place

>>3382

Do the playstation RGB lines need to have 75 Ohm resistors in series as here >>3337 or are the 220 uf capacitors enough?

>>3383

I don't even think the ones listed in that picture are needed, based on http://members.optusnet.com.au/eviltim/gamescart/gamescart.htm at least.

>>3337

BTW, shouldn't the resistor and capacitor connected to pin 6 of the LM1881N be grounded? It's grounded in the datasheet.
