PSNee problem on PAL SCPH-1002 model PU-8 MB

Post by VEGETA »

Hello,

I have done PSNee on my PS1 model PAL SCPH-1002 with motherboard PU-8.

here are pictures of my mod: https://imgur.com/a/f5dc1Hd

this PS1 had a previous model (using PIC chip) but some wires were already loose: https://imgur.com/a/JuOs2sX

I revised the PSNee guide several times, checked continuity, soldered perfectly nice...etc. but no result. the console starts and then nothing.

I attached a picture of my games, probably some of them are original like that Crash game. When I put the crash game the console sometimes displays the beginning screen showing SCEE but sticks there... as seen in last picture.

is this a laser issue?

I tried my newly copied digimon world 2 on a PSone which has an issue of output picture and the disc worked nicely.

kindly check and see what wrong thing I did.

Notice that I flashed the arduino pro mini using USBtinyisp the proper way and verified the chip worked before by flashing the blanking sketch.

best regards

None of those games are originals. PlayStation discs doesn’t look like that.

If I remember correctly you need to uncomment sections of the Arduino code depending on your console model. Did you do that?

I also program using USBTinyISP from the Arduino sdk. So that should be fine :)

I uncommented the line for pro mini yes.

I know tinyisp is ok but i mentioned it if people suspected i flashed the bootloader.

is there anything wrong with my wiring? what could the problem be?

Just to make sure. You uncommented

Code: Select all

#define ARDUINO_328_BOARD
right?

Other than that I’m not sure. Assuming your wires are correct, the installation pdf in the github repository recommends using short wires. Maybe yours are too long and that causes issues.

I did look at your pictures. You could easily cut the wire lenght in half if you installed it on the same side as shown in the pdf.
