If you want a stick with more than 32 GB then you will have to create one using a Pro Duo adapter and one or more MicroSD cards to achieve the capacity you desire. The maximum available space that the Pro Duo was manufactured with is 32 MB.

What is a High Capacity Pro Duo Memory Stick?Īs we all (should) know, the PSP uses the Pro Duo format for it's external memory card. You may find after reading all the information presented here that you have no need to go beyond ~200, ~400, or ~500 GB in size based on other usability factors I will discuss below. Have a working high capacity Memory Stick combination? Please post your info! I will leave it up to others who have the available hardware to test this. Practically however it may be that the adapters on the market today have a limitation or that the CFW will not indeed support such large sizes. Theoretically, the information in this guide should be attainable for MicroSD cards of 256 GB, 512 GB, or even 1 TB in size. This means the largest high capacity setup I have personally tested is 400 GB. There is a bit more detail below regarding FW versions (which are really beyond the scope of this guide).Īdditionally, all my tests were done with MicroSD cards up to 200 GB capacity (because I got a good deal on them).

The below has all been validated on this device running currently running 6.61 ME 2.3, though the vast majority of this should work on all of the standard PSP models using ME or PRO. NOTE: All my practical experience is on an original PSP-1001 (phat/fat) model. There are a few myths and a lot of vagaries about this topic and I hope to clear some things up. I'm hoping this guide/thread can become the definitive place to discuss these issues as much of the information and guidance is scattered throughout this and other forums. I wanted to make this write-up for the community at large to discuss how to go about obtaining/creating a high capacity memory stick for PSPs.
