Memory Adapter for PS2, MX4SIO(Memory Expansion for SIO) SIO2SD Memory Adapter Replacement Memory Reader for PS2 Fat Console(Blue)

The unit works, if you don't know about the subject, I recommend watching several tutorials on Youtube, after seeing what the issue was, he was able to get it to work, he used it in fat32 mode, not exfat. It runs just as fast as an hdd, better than using the traditional usb. The product has good quality, one point to take into account is the compatibility of microsd, not all will work well, at the moment I use ADATA and it is slow, unlike Sandisk, so try a good SD.

I tried it on OPL and it did what it needed to do.

Funciona con mi PS2 Fat sin problemas, solo hay usar Free MCBoot, y buscar el OPL que reconoce el MX4SIO (ya se pueden conseguir la memorias de PS2 con el software precargadao) y una memoria SD compatible, en mi caso uso una SD Kingston de 128Gb formateado como exFAT y no tengo problemas al cargar mis respaldos de juegos, en mi caso el láser de mi PS2 ya no funciona por ello de usar un método alterno para cargar los juegos y estoy muy satisfecho con el resultado

I tried for like 2 weeks to get it to work. Followed every instruction I could find!! Yes I have the most recent fmbc, maybe I'm doing something wrong Idk.. I didn't use a sand disk.. cool idea though

This takes a micro SD card, don't buy a full size one like me!My main concerns buying this were:A) what do you need to get going?B) do the games load quickly/comparable to disc?There's a bit to get figured out, make sure you've got a FreeMcBoot memory card and check to see what the compatibility is for your PS2 model. You've gotta get OPL set up on that same memory card using a USB drive (make sure you get the beta), but once you do this card works effortlessly. I got a 128GB lexar micro SD personally, I have read there are certain cards that aren't compatible so look into it.The games run almost indistinct from disc, I genuinely forgot I was playing off a memory card slot. It's really smooth. You may notice slight variation if you're super familiar with certain games, but I didn't notice anything. The card itself also fits into the system just like a regular one, a nice fit, though the SD card slot is maybe a bit too recessed. It's not a huge issue though.Hopefully this helps anyone like me who had specific concerns about the product, I would say it's absolutely worth picking up.
