I am (as always :) ) looking for feedba...

Re: FreePSXBoot - arbitrary code execution with ONLY a memory card (no game needed)

I had this idea in mind since years, but never took the time to actually work on it, (and I doubt I have the skill to reverse engineer the bios code) so, very nice job on that ! as someone already pointed out, you can use my memory card manager tool to import a save to a memory card easily using th...

A new release has just been posted, feedback is welcome. I can confirm it works with 9002 with a cheap knock-off memory card.

FreePSXBoot - arbitrary code execution with ONLY a memory card (no game needed)

Hello, 2 weeks ago I stumbled upon a video by Modern Vintage Gamer: https://www.youtube.com/watch?v=8b5UX5xd-lE Now, I have never developed for the PSX, and I had never even owned one, so I was extremely surprised to learn that arbitrary code execution on the PSX required a modchip until 3 weeks ago...
