This is a new PsNee modchip for the PlayStation 1.
I use genuine Atmel chips purchased from suppliers like Digikey or Mouser. Each chip is programmed and tested before being shipped.
PsNee modchips have a great set of features allowing the chip to be easy to install, compatible with pretty much all PS1 consoles, and compatible with all games.
- Compatible with all PS1 consoles from the original SCPH-1001 through the slim SPH-101. There are a few exceptions though, so read the compatibility section.
- Play game backups from any region.
- Play genuine games from any region.
- Works with all games, even anti-modchip games like Spryo 3.
- Installation only requires 6-8 wires to be soldered. Read the installation section for more information.
PsNee modchips are compatible with most PlayStation 1 consoles, but there are a few things to keep in mind.
- If using an ATtiny PsNee chip, PAL PSones (SCPH-102) systems won’t be able to play non-PAL games. There is additional region locking in the BIOS. ATmega PsNee chips are compatible, as well as ONEchip modchips.
- Later Japanese systems, starting some time during the SCPH-3000’s, and everything after, won’t be able to play non-NTSC-J games with a PsNee. There is additional region locking in the BIOS. You can either swap the BIOS chip with one out of an American console, or patch your backups to be NTSC-J region.
I put together a comprehensive guide covering how to install PsNee modchips into every board revision of the PlayStation 1. The guide covers how to identify which board revision you have, and how to solder the chip into your board.
The guide is available on my website. Here’s a subset of that guide explaining which board revision applies to each console model, along with links to the diagrams for each board revision.

There are two configuration options when ordering a modchip.
- Wiring: whether you want the chip to come with wires attached or not. If you select to have wires attached the chip will come with a ~12″ 30 AWG wire soldered to each pin.
- Version: whether you want the ATtiny version or the ATmega version (I only sell the ATtiny version at the moment though). ATtiny supports everything the ATmega does (with the exception of PAL PSone BIOS patching) at a lower price and smaller size.
