Free Memory Card Boot 64MB 1.966 for FMCB PlayStation 2 PS2, Plug and Play

Works as described. this product DOES work on 30001 Models, despite what the description says.

As someone who still regularly uses a PlayStation 2, this Free McBoot 1.966 memory card is easily one of the best upgrades you can make to the system. It turns an old console into something far more versatile without needing to open it up or install a modchip. The biggest strength here is how simple it is to use. You literally plug it into your PS2, power it on, and you’re greeted with the Free McBoot menu. From there, you can launch apps like Open PS2 Loader, run games from USB or a hard drive, and access a ton of homebrew tools. It’s genuinely impressive how much functionality this adds with zero setup required. Performance-wise, version 1.966 is stable and widely supported, and it works on most PS2 models without issue (aside from certain later slim models with specific BIOS versions). That makes it a great entry point if you’re just getting into PS2 modding. The 64MB capacity is a nice bonus compared to the original 8MB cards, giving you more room for apps and files. That said, I wouldn’t rely on it as your primary save card. These larger third-party cards can sometimes be less reliable for long-term save storage, so it’s better to use a separate official card for saves and keep this one dedicated to Free McBoot and homebrew. If I had one complaint, it’s that the included software setup can vary depending on where you buy it. Some cards come preloaded with a lot of apps you may not need, and organizing everything can take a bit of learning if you’re new to it. Overall, this is an incredibly useful and affordable way to unlock the full potential of your PS2. Whether you want to preserve your game collection, experiment with homebrew, or just modernize how you play, this memory card delivers exactly what it promises.

Doesn't work with the last PS2 aka the 9000 sph whatever the heck. But upon diving deeper into these they do work on the correct PS2 and it's kinda awesome. If you have a FAT PS2 it'll work guaranteed.
