My port of the old-crow mod for the PS-One System
My port of the old-crow mod for the PS-One System –
This is my first release in 10 years for the old PS-One, dated from 02/20/2008:
After 10 years of the original modchip design for the PSX machines which used the older PIC 12C508, we came across a bunch of un-modded new PS-One machines, and since we had the old source code for the PSX modchip, and the original design used the PIC 12C508 chip, which is hard or costly to get these days, and there is tons of the newer 12F629 chips around these days due to the Wii-mod. We decided to release to the world, our quick and dirty recode of the old Classic 4-wire mod for the PSX using the 12C508 which was originally coded by the famous Old Crow (Scott Rider), and updated it to support the newer 12F629 chip. Included in this package is the our source code, plus a complied HEX file for programming the 12F629, and a bunch of install diagrams from various sources.

If you have any problems using this code. - just message me here.
I know this is an old thread but
I saw in your source code file that you have this here:
removing it should stop the thing from going to sleep and it should technically allow people to boot multiple disk imports or backups. Is there any purpose to the loop other than to put it to sleep after boot up?
goto loop_4_ever ;guess!
I'm guessing this is required so it behaves like a "stealth" modchip and doesn't trigger the anti-modchip protection of the newer PS1 games.
Incorrect, this source has no stealth functionality, in theory removing these lines would in fact allow for multi game backups, i have tried (half-heartedly as it were) to create a stealth subroutine with multi disc ability, however i failed to do so before i had to return to real life (i gave it about a night...haha, maybe i will return to it one day.)

Some Assisstance –
I'm looking to mod a few PS1's for some buds for Xmas, i've got a modded PS1 myself but i purchased the "8 wire stealth chip" from another store, this store has jacked their shipping prices through the roof and so i found this guide in order to save me a little cash.
My first question is WHICH board do i get? I've found a website that sells these boards link included hXXp://www.microchipdirect.com/ProductDetails.aspx?Category=PIC12F629 however there are many different variants. (E/P I/P E/SN I/SN etc. etc.) which model do I need? does it make a difference?
Also when it comes to programming these boards, are they programmable over USB? I've access to many computers through my profession so if i need serial that won't be an issue. **EDIT** im assuming this ( hXXp://robokitsworld.com/index.php?main_page=product_info&products_id=57&ze nid=lqdtcp6iu1q1peakk7bqe93ur6 ) will work for programming the PIC12F629 (the website says it's compatible)
I've got very minimal experience with microchips (most i've had was programming an ATmega32U4 over USB with pre-programmed HEX codes) however after reading this guide it seems very simple and do-able, i just had a few questions.

is there any chance you have the Anti-Piracy (AP) hex. for the 12C508/9
