Here you go. You can use the 3.5V and ground connection from the PU-8 install pic.
Perfect as always, rama3! :praise

Picked up an old unit; I think the CD drive is near-enough shot, but I can always replace that at some point :D will let you know how it goes!

I wish I did. I might pick up one of the simple kit ones soon, not sure how much help it'd be though.

Yep. It sounds like you initially flashed the ATtiny version onto the Arduino, right?
I don't think the IDE will allow you to do this but it's surely possible somehow.
It's best if you disconnect the 4 signal wires (power wires can stay on) and check PSX functionality.

no I made very certain to ...

So yea, zip her up! :p

I still get the same result on mine.

I think I might have to completely disconnect it to test if the unit functions normally without any modifications.

I haven't tested my latest changes on all configurations but I know it might fix some issues you guys have.
So here you go.

Okay, that looks to be correct :)
How did you program it? I don't see remains of an ISP flasher.

I used an FT232RL FTDI USB to TTL serial converter adapter, like this one, https://www.amazon.com/dp/B00IJXZQ7C/ref=cm_sw_r_cp_apa_vTEzzbDM1M9RY
I'll try re flashing it but it showed that it completed ...

LiGhTMaGiCk: Post a picture please.

damopinn: I found / fixed a problem that could be causing this. I'll update soon.

I knew you would say that, I'm the doofus who decided to put it back together screws and all before verifying that it worked. :P https://www.dropbox.com/s/ifep4yzeo74fj6b ...

Pro mini 16Mhz is perfect and use it with 3.5V.
I've tested these boards installed in a PSX with variable 3.5V supply and they work fine down to 3.0V, which is the minimum before the PSX power supply controller shuts off the rail ;)
