PSX modchips

bartre · 07/25/2017, 04:15 PM

anyone around here messed with these?
I've got a few systems I'd like to toss a chip into primarily for the sake of native booting imports.
there's several models, I just want to know which one I should use for this purpose

seieienbu · 07/26/2017, 06:56 PM

Just a thought, you can pick up a Japanese system for $40 or so. I don't know what modchips go for these days but I doubt if it's that much more expensive than just getting another console...?

SignOfZeta · 07/26/2017, 07:19 PM

I don't know what's been invented since, trick features and stuff, but the last time I was in the market (maybe 2002 or 2003 I bought a PSOne and chipped it) development had kinda stopped since the chips played every game from every region legit or boot. I suppose some kind of PAL help would be nice, Gameshark function, maybe VCD functions (these actually exist!) I'd think anything would do. Just buy a modded PS that died in 2001 and rob the chip from there.

I can't even find any PSX modchips for sale anymore. I'd like to find one to put in my PSOne with LCD screen.

well the thing is they're pretty much all based on a small PIC, so you can program them yourself.
or buy them preprogrammed for like $4, seems like a better solution than getting another system to me.

yeah, the problem isn't necessarily sourcing them, it's a question of what type to put in

I think MM3 works on all USA consoles and last i heard was still one of the best ones. There is also the mayumi v4 which i think also works on all versions of USA consoles (which i forgot about till just now).

I was mainly answering HuMan who said he was unable to find them for sale.

here is a link to a mayumi v4 (probably can find somewhere else cheaper). i think the main difference between them is the MM3 uses the clock on the ic and the mayumi v4 uses the clock on the console so is supposed to have more reliable boots. either one im sure will work fine.

there is also Zer0-2k11

looks like hes out at the moment, but if you order from him he will make sure you get the right one for your model.

Medic_wheat · 07/27/2017, 10:41 AM

Wow these mod chips are pretty cheap.

However since I am as capable of a moder as I am a secrete agent of space and time I'd have to find a modded.

Did you check any of them to make sure they aren't already modded? Mod chips for PS were *really* fucking popular at one point.

I will just chime in and say Zer0-2K is an awesome seller, worked with him many times.

GohanX · 07/27/2017, 02:03 PM

I've bought the MM3 from Eurasia. IIRC they do work in all PS1 systems, you just wire the pins to different places depending on the revision of the system. I've got an OG launch model and a PSOne that have the same chip. It's super easy to install in the regular PS1 systems, you need some decent skills to put it into a PSOne though with the super tiny solder points. Voultar's mod shop sells premodded PSOne pcbs if that's the model you want and you're feeling lazy.

DeshDildo · 07/27/2017, 04:04 PM

I'm over here still rocking my Goldfinger "plug in" from 2000 and disc swapping my life away.

I wouldn't mind. Thank you. If you happen to have the Playstation 1 (Version SCPH-1001/2) that has RCA-inputs I'd be highly interested.

in my research, those ones are among the most unreliable when modded.
according to the internet (the worlds most reliable resource) the boot process was a little different on those, so the chips only have like a 70% boot rate or something.

that said, I've got 2 of those systems that I'll be trying the chips out in and I will let you know how the chip works out.

SignOfZeta · 07/27/2017, 09:22 PM

Does that one even need a chip? I thought you could just trick the door switch.

Neat.

To be honest I'd be interested in both.

One for practical use, and the other to hook up in my hi-fi audio system. It's small, and hodgepodge, but fun to piece together a little audio bliss.

ClodBusted · 07/28/2017, 12:57 AM

There's a small pass through adaptor made by Sony that had MiniDIN S-Video, RCA Composite Video and RCA Stereo Audio outputs. On the other end of the adaptor, there was a socket for attaching the regular A/V cable (no matter if Composite, S-Video, RGB or YPbPr). I think it was intended for use with HiFi systems and Lightguns.

EDIT: Model names:

SCPH-1160: grey (PS1 design). Has Composite Video and Stereo Audio

SCPH-10130: black (PS2 design). Has S-Video, Composite Video and Stereo Audio.

Both adaptors should work for PS1, PS2 and PS3, since the pinouts on the Multi AV jacks are the same (the only difference: PS2 and PS3 are able to toggle the RGB pins to YPbPr component video via system menu).

There's also the myth of the earliest PS1 revisions being superior CD-audio players, as told by ~~audiophiles~~ idiots. That stupid myth has been busted long ago.

Thank you for the information. Oh so it was a myth about the CD audio player abilities of the first PlayStation?

GohanX · 07/28/2017, 01:46 PM

It was exaggerated to be sure. They sounded slightly better than other game systems but don't hold up next to actual real audio gear in my experience. 99.9% of people wouldn't be able to tell the difference at all.

Arkhan Asylum · 07/28/2017, 01:49 PM

It just seemed better because they were comparing it to ones being used with RF adapters, lolol

Medic_wheat · 07/28/2017, 01:56 PM

To be perfectly honest.

When someone tells me

This hi-fi set up with

A pre amp

Amp (tubes)

Floor speakers
Etc etc etc

Producing

A warm sound

A soft sounds

Unparalleled sound

I often don't hear a difference.

Now to be honest I have a hearing impairment so my range of hearing isn't that good.

At most I can't tell when something sounds bad

Sound warping
Static

That sort of thing.

So for me I just pick things up with in a modest budget.

I am not ken to spend $2,000 and up for the more expensive vintage or coveted due to name brands stuff some people are.

All my things in my hi-fi set up have been from Salvation Armies, cheap eBay listing, or local yard sales.

And I go by the idea of if it looks pretty has a lot of metal components (not plastic) with fun VMU displays and what not I'll probably add it to my set.

Now a PSONE (plastic) does not fit with that set up. However being also a person who enjoys video games I thought well shoot these things go for $10-25 it might be fun to use as a CD player.

No no. The method I've used you can do without touching the CD when it's in motion. I'm not sure if I can recall it though since I only used it in the couple of years before mod chips were invented and when I try to remember it I start confusing the SS door switch trick. This only works on early models and possibly no US models. Again, it was a long time ago...

There is a SS swap trick that few people seem to remember that also doesn't require you grab a moving disc. I do remember this one. It only works on CDRs though, you need a soldering iron or one of those shitty PAR carts to defeat region. This only tricks the SS into thinking your CDR is real. The PS is dumb and can't tell the difference.

Arkhan Asylum · 07/28/2017, 03:19 PM

If you have a nice setup the sound is better, but only if you're really looking for it.

It's nice to hear great separation of sound with vinyl.

Anyone doing all that shit with a CD is being a moron.

The PS is dumb and can't tell the difference.

I'd be very curious to hear how this method works.

but to the point of SS vs PS copy protection-
on SS, the copy protection and region coding are two separate things, where the PS copy protection is also the region coding.
On PS it works something like this-
system has it's region code (SCEA, SCEE, etc.)
when the game is being checked, the system is expecting to read the same code from the disc.
the thing is, this code has something to do with the disc being a pressed disc vs. a CD-R, and is somehow lost on burned discs.
since it's not there on burns, the system says "no i don't wanna do that" and boots you to the system menu.
modchips interrupt this check and just force the system into thinking the code is there while the system reads a CD.

saturn actually has the region code stored in the header that identifies the game, meaning it's part of the game data, and gets replicated when the disc is copied.
the copy protection however had something to do with that "ribbon" you can see on the underside of SS discs.
basically, the system would check that, then the game header, then load up the game.

SignOfZeta · 07/28/2017, 06:54 PM

This is what I remember.

You need to be able to trick the door. If you want to just tape it internally that's fine, if it never sees the door open that's fine.

Turn the system on with a legit game and Auto Run off. The system will authenticate the disc and it will keep spinning.

Wait a long time for the drive to go into power save mode. Open the door (the system can't see you open the door) and swap in the CDR software.

Press Reset. The system will reboot and not check the security strip. The game will run.

The auto run setting may need to be in one position or another.

I'm pretty sure this is correct. It's been a long time but I know it's possible with an oval button black Saturn because that's how I played the Lunar 1 remix and a few other games from that time. To avoid going through this every day I just left the machine on for days at a time.

Saturns are tough.

This ONLY defeats copyright protection, not region. The SS in question was switched.

wildfruit · 07/28/2017, 07:01 PM

Just pick up a pre modded ps1. There are bargains to be had. I got mine for about £10 as is , console only no cables controllers etc. It does US JP PAL and boots. O and RGB is very pretty on PS1 well worth a good scart.

SignOfZeta · 07/28/2017, 10:18 PM

Mine won't do PAL on my US machine. I normally don't care but I've been staring at this EU Capcom Generations for 15 years now...

but i would just like to say thanks for posting the model numbers, cuz I've been trying to find those for forever and that is what finally got me one for a good price.

I think PAL games require a special fix on some models.
does yours boot the game at all?

Lol, I'd wish I'd known you were in the market for a passthrough AV for the PS. I'd had an extra OEM one I'd been sitting on for awhile and dumped it like a couple weeks ago to the local shop. I still my original from back in the day which was use with Time Crisis though.
