PDSX v0.3.0 is released. PDSX is a Playstation BIOS pseudo-emulator for DS/DSi. Ever wanted to run PS1 on your DS or DSi, but can't, due to it's impossibility to emulate? Well no worries! I have made something that brings at least parts of the PS1 experience to the DS/DSi! Introducing PDSX, the PS1 pseudo-emulator for the DS(i) that brings the PS1 BIOS to your DS(i)! Remember! This cannot run games, so you're only limited to the BIOS.
