Best modchip ?
Hello,
I have a few PAL SCPH-1002, SCPH-5502, SCPH-7002 and SCPH-7502 units and i was wondering as of 2016, which modchip i should install in those.
It's been a while since I last checked this kind of stuff, so i don't know if there is any solution better than another.
Any recommendation ?
Thanks

I have personally had great success with MM3 chips (you can either flash them yourself using the OpenMM3 firmware dump or buy them from eurasia here's a link for your convenience (US version, if your location is any indication you probably want the PAL version!))
it works with every model up to SCPH-101, SCPH-102 (the last PSOne revision) does NOT function with it (last I checked, that is).
It will work fine for all units you listed [to my knowledge, don't quote me on that].
I don't even think any other chips are made aside from the OneChip but that one's specifically for the SCPH-102 model and will definitely not work for fat playstations.
Oh, almost forgot. note: I'm not affiliated with eurasia in any way and cannot guarantee any quality of service - I'm merely stating that the modchip I bought from them worked fine a couple years back, should still work fine but YMMV and I take no responsibility for any information contained within this post and insert any other blurb here that'll prevent me from getting sued if it doesn't work.

Thanks for your answer, i'll go for that one then.
I don't think i'll keep all these units anyway.
I might only stick with the 1002 for collecting purpose and the 7502 ones since they're the last ones with the parallel port and their ksm 440-AEM drives seem to be the most reliable ones.

I modded one of my PSone SCPH-102 PAL (v1 motherboard) with a OneChip (8 wires) and while it boots everything just fine i, for some reason, now have a black border on screen on the right side when using either RCA or S-Video cables.
But when using this RGB cable it doesn't happen and display correctly.
Is there anything i could have missed or done wrong ?

That sounds like a PAL/NTSC problem to me. Your TV mustn't support one or the other. Try playing a PAL game from RCA, and then an NTSC game. Do both regions have the black border on the right?Squaresoft74 wrote:I modded one of my PSone SCPH-102 PAL (v1 motherboard) with a OneChip (8 wires) and while it boots everything just fine i, for some reason, now have a black border on screen on the right side when using either RCA or S-Video cables.

It happens straight when powering on the console so also on the bios screen.
It didn't before i modded it and any cables worked just fine.

Did you touch the RGB encoder by any chance?
It sounds like the modchip is putting your PSone into a mode which it doesn't support.

I don't think i shortened anything as far as i or my multimeter can tell.
Maybe i should get some proper Kynar wire and redo the whole thing to make sure.

Don't bother. The OneChip forces the console into NTSC mode. That's your problem
Makes complete sense now. That is why it works over RGB.

Oh well as long as i have a proper RGB cable and use that one it's not really a problem then.
Thanks. !
*Edit*
Could this *fix* the problem ?
Looks like point 8 is different.

No, point 8 looks like ground. You'd have to get the OneChip source, or dump the chip, change the video mode offset and re-flash the chip to fix it.
The HEX I beleive is this code here (this is the OneChip code for a SCPH-102 (PAL)).
Pop that through a PIC disassembler, and you should be able to find the correct offset, but it's PAL based anyway, so there wouldn't be a point
