Unknown mods on a PAL SNES

[Yawnn]

Hi everyone.
A few years ago, I was gifted a second hand PAL SNES. Now that I look at it though, I think it may be modded ... Anyone has an idea ? I'll take it apart later today and keep you updated.

Love Super NES's appearance. I have one but a mini classic PAL version. I had real one before but sold for some reasons. I am so happy to have Mini Classic PAL version and I wont sell it ever!

A purple version is ugly, thought!

It could be an RGB Mod.

This is from the Super Famicom:

Could be, but it's only thre outputs insead of 5. Maybe an alternative RCA output ?
Anyways the mod itself seems bent inside the console x)

Yikes, that looks butchered. Second the RGB mod, but more likely a component mod, since PAL SNES already outputs RGB via multi out. Wouldn't keep that, as it looks seriously shoddy.

Shody is one way to say it. If I find myself a game bit, I'll take it open and look at what I can do. Though 3 is a bit short for component ain't it ?

Not if the multi out is being used for sound. Three outputs for YPBPR and then take the left and right audio from the multi out.

If it does not include audio then two of the five (the red and white ones) are audio and that leaves 3, which is what most video standards use regardless of whether they are RGB or have some fun with luminance and chrominance.

Also if you are going to tidy those up pick yourself up a tapered reamer, handyman's reamer, step drill or something similar and make it nice (don't know French terms offhand). I am actually impressed someone made holes that bad in plastic.

I'll get those, with a little research should be able to identify everything. Thanks for the help !

if you ever find out what it is, make an update! interesting stuff. definitely not RGB, and I don't know why they would bother with component or composite or something out either. Plus, it looks like they aren't even lined up with the holes or have any colors, and that maybe whatever was in there fell out even. But still component makes the least and most sense.

I will ! It might have to wait a bit though, I don't have a game bit yet to open the unit.

Update time !

Now with pcb pics !

That looks even worse in close up. I am not even sure I could replicate that.
4 wires on 12 pin header. 1 wire just being a ground so I am guessing they are commoned up there.
In their numbering 9,11 and 12.

Didn't see much on

There is an A/V pinout.
If it is the same numbering then that is composite video and left and right audio.
Screenshot of the PDF from the second link above

That is an odd thing to do but if the port is broken or they lacked a SNES lead then eh. For the effort considering far more useful pins are right there

Hard to tell from those shots but it looks like
wire marked "X" goes to 12 (right audio)
wire marked "-" goes to 11 (left audio)
Both those are stuck together still as they leave the header in https://gbatemp.net/attachments/104001801_612766145999475_7760378687571555561_n-jpg.213195/ they look like they might still be stuck together.
In which case X (right audio) goes to the middle and - (left audio) goes to the left in that image (not the yellow one).

Another Free floating "-" is the ground, there are several nice grounds on pins 5 and 6 but to each their own I guess.
What looks like X and free floating is going to 9 (composite)
If the person doing the mod did the colours conventionally then the yellow should be the composite out. It does have a X going to it.

Edit short version if I am right
Right/most towards the front/yellow should be composite out
Middle should be right audio
Left (most towards the back, not yellow) should be left audio.

Thanks for the analysis ! So this definitely looks like an output mod, but I can't really comprehend why they would do it this way. I'm not even sure it would be a good idea to actually look at the signal I'd get from this

The SNES video cable is custom so if they lacked one for whatever reason (I believe it was shared with some other things) then that is a quick and easy way to simple connect it to a commonly seen TV (RGB and component was not that common on European TVs until not so many years ago, indeed RGB still is not) or VCR with commonly available cables, not to mention it might also be a step up if the only cable they had was RF before that.

is it possible to have 3.5mm audio jack so i can play with head phones

Probably would have been better to make a new thread but all good.

Depending upon the headphones the red and white audio ports could power something (RCA to 3.5mm cables are as common as dirt for a reason). That said volume control will be tricky and they might be quite low volume as well depending upon the impedance of your headphones.
The SNES does not have a hidden provision for headphone audio that I am aware of (I could be wrong, or there could be some revision that does) like some other systems.
To that end you would probably then want to find a small amplifier board (there are loads of kits you can buy off the shelf, and small audio amplifier is one of the main introduction to soldering/analogue electronics/audio electronics type projects so there should be loads of examples).
If you want to go really fancy then as well as amps there are bluetooth audio modules that will take line in audio so you can tap that and connect it to bluetooth if you wanted to go that way.

We could get fancier still and you could tap things other than at the connector but let's not go there for this one.

Personally I am a lazy type so would sooner look to have the audio come out of my screen and then tap that for my headphones but it does seem audio out is a rarity on modern devices and not everybody wants to pull apart their screen to tap it for audio out. Likewise if left-right audio is at the cable (hopefully you are not using RF video out) you could throw that into a hifi stack (or another little amp you bought -- they really are cheap as anything and available everywhere) and skip the whole problem.
