Returns due to a failure of understanding this will be subject to a 20% restocking fee and no refund on shipping costs. We consider this an Intermediate Level modification. Meaning only those with some experience modding, soldering, etc. should attempt this modification. Stone Age Gamer, nor the manufacturer will warranty modifications that are not done by an approved modding service provider. Check out the Mod Guides HERE.

PSIO is simply a development cartridge that plugs into your PlayStation’s Parallel I/O Port. It allows you to instantly see your software running from an SD Card on real hardware, making it the ultimate developers tool, as well as making it invaluable for debugging.

    This thing is sweet. I paid for the mod service and was having a weird issue that I originally assumed was due to the service. SAG support was great and helped me diagnose what the real problem was (bad HDMI adapter).

    PSIO is a dream to use. But tricky to get certain games on there as you have to combine track files with their included software, but it works!

    Finally got my hands on a PSIO after 3yrs of trying

    What a wonderful item for the PS1. A must have for those that want to still use their disc drive. Thank you so much SAG.

    Paired with a RAD2X and MemCardPro!

    Posted by Eric Walchli on Oct 31st 2023

    Bought this and made it into a project with my father and I. We bought a RAD2X and MemCardPro also with brand new controllers, and we`re in heaven! This thing does exactly what we want while still being able to use our old disc and our newly build optical drive we cleaned up and put a new laser into. highly recommend for people who want to keep the Disc, if not other options are great too!

    Great as expected

    I was looking forward to the PSIO and was hoping to have more trouble to install but, it was not that hard. Worked perfectly!!!

    Great for those who want to leave their disk drive in tact.

    PSIO is a very competent PlayStation ODE, that has continued to get better over time. The installation is one of the easier modchip installations I've done, and the box includes some good quality kynar wire. It's not recommended for absolute beginners, but if you've worked a soldering iron before and can follow instructions, then you should be good to go. Updates are a bit slow, but the community is active, the creator is very friendly, and he posts status updates and screenshots of upcoming features regularly. The PlayStation has a bajillion games, and this is a fantastic way to experience your favorites again, and to experience new ones as well.

    Great Solution

    I love the flexibility of this device, being about to run translations off micro sd cards, while still being able to play my existing original disc library. You will have to spend time setting games up in the correct format however, so definitely read the manual.

    Excellent product! I did the installation myself on my PlayStation SCPH - 7001 (PU - 20) Everything is working perfectly, I recommend the PSIO for it keeps the CD drive intact so it is possible to play with both CD and SD card.

    This site is excellent, I received my order and I was not taxed, the product arrived very well packaged.

    A must have if you want to play originals and backups.

    Posted by Damien on Apr 23rd 2021

    There are a number of Optical Disc Emulators (ODE) on the market, but PSIO is the only one that lets you keep your CD drive intact. The compatibility has gotten extremely good and accurate over the past year. The chip installation is not hard if you’re decent at soldering. There are traces you must cut but if you’re carful and double check everything you should be fine. If you don’t feel confident then definitely have Stone Age Gamer do the install. PSIO is a great product, I highly recommend.

    Nearly perfect.

    Posted by Doug Plummer on Apr 22nd 2021

    The install was easy, I wish it had an easy way to organize the games in a folder system or even a gui SD card organizer for the PC that you could add genre if not a folder system.
