Tested with SCPH-102 with 4.4 and 4.5 BIOS flashed files using a SCPH-7502 console. PlayStation Development PC: Windows 98 SE, Pentium 3 at 400MHz, 128MB SDRAM, DTL-H2000, DTL-H2010. Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), PSIO Switch Board, DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34. I also found a way to (hopely) always recover corrupted/modified memory card using the old Wipeout (1995) game (my problem appeared with 4.5 bios exploit - the memory flashed with SCPH-102 BIOS 4.4 exploit or SCPH-5502 BIOS 3.0 were still correctly recognized by Memory Card Annihilator v2.0 while the 4.5 was not - also OddWorld: Abe's Oddysee was NOT able to recognize the memory card flashed with 4.5 exploit, i always got a system crash):Ġ - insert a WORKING memory card in slot 1 (YES, you need at least 1 good memory card - it will probably work on slot 2 too)ĥ - answer 'YES' to the format 1st requestĦ - SWITCH the good memory card with the modified (corrupted) oneħ - answer YES to the 2nd format request Ĩ - done ! your memory card is good again :) what is a good pot adjustment for SCPH-5501. Using FreePSXBoot exploit for BIOS v4.4 is working fine ! Thank you very much ! I managed to get the correct bios version using the suggested PSX BIOS Dumper 2.6 tool. This section has photos of some successful installations which you can use to get a better understanding of how everything is wired and positioned.Well the problem was exactly that, I used wrong bios version (my SCPH-102 is v4.4 and not v4.5 i previously flashed).

When soldering to pin six be careful, you don't want to apply too much solder and bridge nearby pins on the chip.

So, if possible, adding that as a file name option (scph7003 bin,scph1001 Provided by Alexa.

Be careful when soldering to pin four, if you apply too much solder, or press too hard, you may knock a component off of the board, or bridge the connection with nearby points.

Placing the chip where the pin eight circle is seems to be the ideal location.

Pin 4 can either be connected to the pin 4 location in the diagram, or pulled high by connecting it to pin 1 on the chip.

Don't connect pin two of the chip to anything.

Cut your wires to be as short and direct as possible.

Here are some tips I have for you when you are soldering your chip into the PU-20. Pin four connects to the right side of the capacitor, which is the topmost component in that spot. Pin six connects to the bottom left most leg of that chip, and pin five connects to the pad to the left of the white line on the board. The diagram isn't the cleanest so I'd like to clarify a few points that are unclear. This board was used exclusively with the SCPH-7000 series of consoles.įor more information about MM3 chips click here, for more information about PS1 modchips click here.
