Re: UniROM V6 - New stuff and things.

The nocash unlock is not going to work on the SCPH-7000 (or any other console with a Japan region CD controller) because the CD firmware doesn't support it. Normal booting of in-region discs should still work, though.

Re: Mysterious problems with NTSC-J Um Jammer Lammy

As far as I remember, the 'Aging Test Disc' was released here . Yeah, that one is the CD drive aging disc - there was a system test aging disc too, and that doesn't seem to have ever leaked. Seeing as the hardware is getting old now, maybe it would be a good idea to write some test software - testi...

Re: Mysterious problems with NTSC-J Um Jammer Lammy

Maybe a problem with the game code branching differently in some areas because of the regional differences (in the BIOS, for example). All it takes is an expected SPU DMA routine delay that somehow takes more/less time on the NTSC-U machine. I tested it using the same configuration he did (SCPH-550...

Re: Mysterious problems with NTSC-J Um Jammer Lammy

I just realized that I had an unmodded Japanese PSOne lying around. The game works fine on it, so this is not really a problem anymore. But this is still a very mysterious issue. It is very strange - all I can think of is that it's some sort of edge-case hardware problem like bad SPU RAM that this ...

Re: Mysterious problems with NTSC-J Um Jammer Lammy

OK, do you have access to another console to test with? I've just tried this using an unmodified SCPH-5501, an old Action Replay cart flashed with UniROM v6 and a original Japanese copy of Um Jammer Lammy (SCPS-18011). There are no strange noises and it sounds identical to the same disc booted on my...

Re: PS1 Dev Console Power Cord Troubles

There was a special power block that was only used with those debug consoles. There is also a specific PSU that came with some Sony VAIO laptops that will work, but I imagine that would be as hard to find now as the original one that came with the console. The other option is to open the console up ...

Re: Playstation schp 1000 region lock

If it's an SCPH-1000 it will have a PU-7 board in it. Unlike the US and European markets where SCPH-1001/SCPH-1002 covered a wide range of hardware specs the Japanese changed the part number when they changed the hardware.

Re: Playstation schp 1000 region lock

I can't be 100%, but I have a unit here also made in the Kisarazu plant with a higher serial number than that and it has the old boot ROM in it, so I think there is an excellent chance that one does too.

Re: Playstation schp 1000 region lock

It's true for most SCPH-1000s - this was a bug in the boot ROM and it was changed late in the production run so you might be unlucky and get one where it doesn't work. You do need an original NTSC:J disc and there is a specific procedure you need to use. Turn on console with no disc in it and go to ...

OK, to fix the first error you need to change the contents of line 1 on the file to reflect where you have the cdgen files installed - for example on my machine the correct path is C:\psyq\cdgen\LCNSFILE The second one is probably again that the path doesn't exactly match your installation, so reche...

Re: Sony DTL-H2000 Mechacon Firmware

Having had a chance to look at this dump, here are a few observations: 1) Although it's a 32K EPROM, only the upper 16K is being used and the lower 16K is filled with 0xff - this is consistent with the socket on the piggyback chip being wired to take either a 27128 or a 27256. 2) Unlike the producti...

Re: PlayStation PAL Series Colour/Color Modification (PAL60)

Tried it and no dice. It will boot in B/W in both PAL and NTSC mode. I checked the wiring and it's done correctly. Maybe it's because I have a early PU-8? I know the S/N on the board ends in -467-11, and at least I couldn't find the 0 ohm links for the main 53MHz XTAL. I don't think so - that part ...

Re: PlayStation PAL Series Colour/Color Modification (PAL60)

It's dependent on your TV, and which video formats it supports. All the PAL consoles starting from the PU-20 (SCPH-7002) will always output a signal with a 4.43MHz PAL subcarrier irrespective of the video mode. Without this mod, the effective video mode when running a 60Hz game will be NTSC4.43 and ...

Re: SCPH-1002 Modchip(MM3?)(PU8,PIC12C508A)(Questions)

Unfortunately, no - the chip with multiple "dino modes" was Stealth 2.8a, and that didn't save it, so you had to hold down the RESET switch for 3 seconds to switch mode every time you turned the console on. Mayumi 2.1 (the one that ran on the PIC16F84) has the current operating mode stored in EEPROM...

Re: SCPH-1002 Modchip(MM3?)(PU8,PIC12C508A)(Questions)

None of the old chips managed 100% stealth on PU-7 and PU-8. Mayumi 2.x and the MM2.x series chips were pretty good, but they all used the same basic approach that timed the boot process and used the x1/x2 line from the CD controller to work out where in the boot process the console was. This was so...

Re: Question about PIC12F629 for PS1 Modchip

It will work. Electrically those SO package parts are identical to the DIP ones. At the least, I would recommend getting an adapter PCB to break the leads out to 0.1" pitch - it makes it a lot easier to solder and also a neater installation. If possible, get a programming adapter too - these just si...
