Original Post:
I just bought an InterACT Game Shark v2.3 on eBay (Should be this one), and have looked into UniROM, and know that at the very least, I will be able to boot backup discs and whatnot, which is good enough.
My main question, and threads here don't seem too clear on an answer, is can the parallel port be used for PSXSerial/Psy-Q deployment? If so, what kind of cable or PCI-E interface should I buy? I only have a modern PC and Arch Linux/Windows 10.
That's fine if it doesn't, I just wanted some clarification.
