Playstation 1 Mods - BIOS & Stealth Modchip Install
I've had this Japanese PS1 in my possession for several months, I thought it would make a great candidate to install a PsNee stealth modchip in it, however there is a caveat to working on this type of system in particular.
Japanese PS1's have extra security measures hidden inside the boot ROM, making installing a stealth modchip almost useless. In this video I will be swapping the BIOS chip with a custom flash BIOS chip along with a PsNee stealth modchip.
