PS1 Scart transcode to Component? Then Light Guns

Post by mongusa32 »

Does this work? I heard PS1 can't do it but isn't transcoding different than unsupported component output? And will light guns work after? I just want best picture for 480i crt tube tv with light guns before giving up and just using s-video.

On the side note I read somewhere that someone used a PS3 component cable on a PS1 SCPH-5501 model and it works. Unfortunately I have the 1001 and heard component didn't exist around that time. Maybe Sony added that function to it on the later models? Can anyone clarify this?

yes, raw transcoding works.

You could use a PS2 instead though. Here you get native component output.

no PS1 model supports native component output, so I doubt that.

If you're only using 480i, why not just use RGB? It looks better than component anyway... :?

I use a PS2 component cable on my PS1, along with a breakout box, for RGB. Works nicely for that :-)

I have a slim PS2 and heard it emulates PS1 so I felt going og was better. Anyway Light guns will still work after transcoding?

AndehX, I'm using CRT TV, no scart connection.

Einzelherz which model was your ps1? First gen?

no, it's full hardware.

he's just using a component cable to output RGB. Won't help you.

It's not clear to me exactly what is different, but the PS2 Slim appears to be missing some PS1 hardware and replacing it with emulation: there are 33 games that don't run on the PS2 Slim. In fact, there are also 6 games that don't run on the PS2 original, including Metal Gear Solid VR Missions and Final Fantasy Tactics.

My Life in Gaming did a pretty extensive video about every possible option for playing PS1 games, and the video options and quirks for each, but for component video output, there are several choices:

1) PS1 with component transcoding. HD Retrovision will be making an adapter for their Genesis cable to do this, but they've said sourcing high quality PS1 connectors is tricky due to different fitment as compared to PS2/PS3 sockets. In the mean time, your only option is transcoding boxes.

2) PS2 with native component output. Some models of PS2 have slightly noisy component output, although most people can't tell the difference (probably varies by display/model). You lose a bit of compatibility, but this is probably the cheapest/simplest option.

3) PS3 with native component output. This was the last Sony console to support analog video output. Major downside: it does not support 240p like the PS1 and PS2, and so you will need to let the console upscale the video. It also adds a decent amount of lag.

4) PSP/PSP Go with native component output. This can actually do 240p to a CRT, but only works with PSN-downloaded PS1 games (unless you mod the thing and run ISOs).

I think I got that all right from memory, but for reference, you can watch this video to see every possible option:

It's still not clear to me, wether the ps2 has full hardware playback for ps1 games or not.

I've heard things from "full hardware", to "the GPU for ps1 games is emulated (maybe because it's integrated into another IC, whereas the ps1's gpu was a standalone chip? Could it be what drove people to that conclusion? btw I don't even know if what I just wrote about the GPU is true, it's just something I've heard).

I haven't heard much about slim versions containing less ps1 hardware though, but maybe it's the case?

I'm speculating, but it's definitely true that the P2 Slim has much worse compatibility with PS1 games. As I said, 33 games don't work, and I've seen reports that some games that do work have graphical glitches, like SotN has some graphical glitches around the moon in some outdoor sections, IIRC?

My guess is that they ditched the PS1 GPU in the Slim, but as I said, speculation.

I thought the last I heard on the PS2 was that the PS1 CPU was emulated in all models, and the GPU was emulated as well in the slims. We had a thread about it pretty recently, it could still be found quickly I'd think.

It's not impossible that through processor revisions random compatibility issues occurred. IIRC both the PS1 and PS2 have compatibility issues with games made specifically for them that show up in later revisions. Seems pretty plausible, to me, actually.

So...just confirming light guns will still work after transcoding RGB to Component? Can anyone recommend any particular transcoder? Hopefully a small one? They're all lagless right?

About PS2's backward compatibility, I read somewhere that on latest models(slim) the GPU was emulated. With all the different info floating around having an extra console gives me piece of mind.

Can't you just use a SCPH-1160 inbetween your PS1 scart or component? Or am I missing something entirely?

Try the CSY-2100 RGB to YUV (Component) transcoder, I used it on my old CRT and never had a problem with light gun games. You'll have to find a way to get the audio out so a SCART switch or possibly what korpse413 showed above the SCPH-1160, I'm not sure if it passes RGB thou.

I'd like to see that thread, I remember reading somewhere that the MIPS R3000A is the PS2's I/O processor clocked at 37.5 MHz with 2MB of RAM all on one chip. I think it's only the fat models that have it thou.

Is it the chip to the lower right of the Emotion Engine processor near the bottom of the board? It has different numbers but a few of the same markings:

The breakout box that I use (like the above) is so that I can us a standard component cable as an RGB+stereo cable. But RGB requires a sync line as well, so I tap the composite out (yellow) from the breakout box and use it as (external) sync on my PVMs.

If you can only use component then your simple options are:

PS1 + RGB Scart cable + scart to component converter. The CSY clone posted by zakruowrath is one that I use and it does a good job.

PS2 + component cable. The PS2 will output PS1 games over component just fine. We diverted in this thread a little in that some PS1 games don't play well on PS2s of varying vintages.

PS3 + component cable. See Guspaz's post.

PSP. See Guspaz's post.


@mongusa32 I wish I could help answer your question but I don't have any light guns or their games to test out. I don't think there's any reason they wouldn't work, as the light gun just takes pictures of the screen (that's my understanding, anyway). If it's a transcoder, there's going to be little or no lag.

Light guns that use a sync signal know when the screen is starting to be displayed, then reads when the electron beam sets off the light sensor in the gun and calculates where it was aimed on screen based on the time between the two. Pure transcoding is for all intents and purposes lagless, and thus shouldn't cause a problem.

Seems like the PS3 would fail for the original thread's question. Since it upscales with lag <= Framemeister, it would also have the same problems with light guns. (It's still outputting upscaled through component as well, so it's not a matter of connection).

Wow I'm speechless. Thanks everyone!

zakruowrath, I have the 1001 with the extra set of rca outs so I don't think I have to a sound issue unless the PS1 shuts those outputs off while av out(scart) is in use(I don't know). And thanks for that link! I don't suppose you know one for vga to component? I wanna try light gun gaming with my DC too. If not, S-Vid will do. Oh, and sorry don't remember where I read that info from.

Einzelherz, I will have to go with the first option but your setup sound pretty confusing so do I have to worry about sync line issue(not that I know what that is)?

Any recommendations on a good affordable PS1 scart cable(unless 2/3 also work)? I don't know much about them like varieties and such.

There is the Toro VGA box which allows 240p,480i and 480p over SCART and if you want VGA in the future it's there. What I want to do in the future when I get a 4K TV without a VGA port is use the Toro's SCART output to the CSY-2100 clone and I'm hoping I can get 480p over component, I don't see why it wouldn't work but I haven't tested it, so I can't say for sure. And glad to know you have a 1001 PS1, I would hope it doesn't disable the AV RCA connectors when using the mulit-out since I believe they designed it so you can use it with stereo systems back in the day.
