@lagomorph sorry for taking over your thread, but maybe you could give me some help with attiny85.
I programmed the attiny85 with ardiuno as ISP without a problem.
But after soldering, the PU-23 does not read any game disc. Neither originals nor backups. After reading the disc, the ps1 stuck at "please insert ps1 disc" screen.
But audio CDs working fine.

It seems to me of memory it can be the internet clock of 85, which is not perfect. The two parameters to modify can be on line 152-153

Not sure about the PU-23. Are you able to get debug info out of it by defining PSNEEDEBUG? If I connect it up to a console I get something like:

If you want more info on serial output, you can find more info on the original forum. http://www.psxdev.net/forum/viewtopic.php?f=47&t=1262&start=40
Seems to me that it's mostly about playhead movement instructions

Ok, thank you guys. It's my first programmed chip ever. Will try to enable debugging.
from psnee.
Welcome. looking again at the message of lagomorph, and the code, the important moment is the !, this is the moment when the chips will send the hack, and that it should come from a problem of clock
from psnee.
Can confirm it's working on PU-23, but can't really tell why. Tested with Dino Crisis.
Only thing I changed, is the define PSNEEDEBUG flag, but didn't need to debug yet.
Also this time, I choose "Burn Bootloader" before flashing the Attiny85.
Is this even necessary and I forgot it in the first place?
from psnee.
It's not necessary.
Arduino bootloader operation introduces boot latency, which prevents proper operation of PsNee if you boot the console with a CD in it.
The bootloader is only necessary, when you want to program with the TxTr interface, if you prefer the SIP which does not need a bootloader.
from psnee.
Burning the bootloader also sets the fuses. Maybe an old fuse value was causing issues. 🤷♂️
from psnee.
I didn't know that it modifies the fuses, it's always good to take as a trick
