A whole tube!! nice
I have about 2 or 3 modded ps1's laying around and a spare ps1 motherboard with mod chip installed and a few other spare ps1 bits and pieces.... just in case
One of the ps1's i purchased a while ago from Evilbay came with a blue odd shaped cartridge that fits into the back of the ps1's parallel expansion port. It allows the ps1 to play imports and backups without actually opening up your ps1 and modding the hardware. It also acts as a cheat cartridge and is made by the same company (EMS) who created the "all in one" action replay for the Saturn. I never even knew these existed back then as i never saw one
On the label it says "PS1 HACKER" a nice plug-mod
