    Awesome service - above and beyond!

    Posted by Mike Lindquist on Aug 28th 2021

    Not only did S.A.G. do a great job installing my PSIO, but after running into some odd issues with my initial unit (which was no fault of theirs), they were amazing and were able to replace mine when I sent the first one back to them. It's been treating me fine ever since (over 1.5 years at this point!) & living that ODE life with my 90s disc-based consoles is so nice and convenient/worry-free :)

    PSIO install went smoothly!

    Posted by Robert M on May 18th 2021

    I had SAG install a PSIO for me a while back and the install went flawlessly. I was sent the login information for the firmware updates, and have had 0 issues updating and using the product.

    This was the original ODE for the PS1, and while new ones exist (MODE and XStation) this one doesn't need to have the CD Drive removed so I can still play my original games.

    If you're looking for a pure ODE solution and don't want to use actual discs, I'd go for the other options. But for me, I'm still using this system a bunch since I still own a good number of the games I grew up with.

    Good soldiering work by SAG, and it's never bugged out or anything.

    Phenomenal service

    Product was sent back quickly, modded and working perfectly, highly recommended. No more switching disc to enjoy your collection. If you're an amateur at soldering this is the best option in my opinion

    The PSIO is a great mod to your PS1 that can play games from an SD Card. Stone Age Gamer has great customer support and helped me with whatever problems I came upon. Buy with confidence.

    Worth it!

    Posted by Nicholas Majcher on Jun 12th 2019

    I grew up a nintendo kid, but for some reason, even though i own NES Multicarts, SNES multicarts Sega Multicarts etc... This thing brought me the most joy. It may be slightly finicky with the certain file types, but once you get the file stuff sorted, this thing is a breeze to use. Also SUPER SPECIAL SHOUT OUT to SAG for instaling it on my PS1. The turn around time was quick, and easy. I would highly reccomend this product!!! - I would also reccomend going through SAG if youre not the best at soldering.
