Arduino DVD Player unlocking

[Hucknallred]

I picked up a Sony BDP-S370 that I needed to unlock & found the thread below. I have no One For all remotes anymore, but I do have an Arduino.
In the thread some arduino code was posted as an alternative to the One For All codes. I'm no expert on the Arduino, but bought some IR LEDs off eBay, tinkered with the code a little and ...... it worked!

Despite a lot of searching I can't find any resources on this & can't seem to find the poster - Hazan. I have a few players to unlock & would like to go this way with them.

Can anyone help?

Thanks

Never trust posted hacks for Sony players.
