PM-41 PAL problem

[impy101]

I've spent the past 5 hours trying to get PSNee to work on my PAL PM-41 but nothing works. I've used Arduino Uno as a programmer and a FT232RL to program Arduino Nano's and Mini-Pro's and neither work. I definitely have everything wired correctly and I checked with a multimeter that everything is reading right. But the PSOne still refuses to read burned discs that my older PSX does read.

At first glance like this it's hard to tell. Did you compile and connect correctly with the bios patch. by the way I give you the link to the new version, with completely revised documentation https://github.com/kalymos/PSNee_V8/tree/test2 Le dim. 8 déc. 2024 à 01:05, impy101 ***@***.***> a écrit :

Same thing I'm afraid. I definitely compiled it properly and there's nothing wrong with my wiring.

My FT232RL to Pro-mini wiring: VCC - VCC, GND - GND, TX - RX, RX - TX, DTR - DTR. Board settings in arduino IDE are correct and for programmer I used Arduino as ISP and AVRISP MKII. Still nothing, all I get is my PSOne sees the discs as some kind of media with minutes etc.

you tested with a genuine disc from another region? I'm not 100% sure, but it looks like the bios patch isn't working. P.S. Little extra tip, used the LED_RUN option, it told you if the region code is sent Le dim. 8 déc. 2024 à 11:26, impy101 ***@***.***> a écrit :

I don't have a genuine disc from another region unfortunately. However, I noticed in the guide that I should be uploading the code with sketch -> upload using programmer. I tried that several times, but I just get: avrdude: stk500_recv(): programmer is not responding

However, when I upload "normally" using Arduino ISP it does succesfully upload.

The recipe I use is really specific, and must be followed step by step.
But if your ISP method works, use it.
I'm not 100% sure, but it looks like the bios patch isn't working.

P.S. Little extra tip, used the LED_RUN option, it told you if the region code is sent

P.P.S Injection with Arduino ISP is always a bit tricky, personally I always test first with the blink sketch ;)
