32GB Memory Stick MS Pro Duo Memory Card for Sony PSP High-speed

Product Information

Unzip the contents of the "PSP 6.61 Pro" custom firmware folder and copy the contents to the Game folder. You can manually recreate this structure by copying it from another working card that formats successfully in your PSP. This process simply entails re-formatting your card through the PC. After putting your PSP in "USB Connection" mode and seeing the drive letter appear in windows we need to reformat.

If you really need all that space on one card and don't mind the waiting while the memory card is initialized each time, then there should be no problems going to the higher capacities. I am happy to report though that although the PSP has issues with the formatting, it appears that once it is formatted properly via PC the PSP has no troubles accessing the cards. While it is possible to go 400 GB+ larger cards are going to have speed penalties when loading the card. When set to automatic, the default PPSSPP language setting will be pulled from RetroArch's Language setting.But in the end other games create new saves and i can start from the beginning and the new saves work.

Buffered mode renders graphics close to what is in the actual PSP, with all the effects and with the least possible bugs.

xBRZ is overall the best option while Hybrid is a slower version of xBRZ and doesn't offers much difference, Hybrid + Bicubic is the slowest one using two effects.

The jit setting enables the Dynamic Recomplier (Dynarec) for CPU emulation. The Dynarec is much faster than the interpreter setting and is the default, recommended mode for supported architectures. If you want to go with up to 128 GB I think most any card will work. To go higher than that you might have a bit more of a challenge finding a card like #6, or some other card that has proved trustworthy for others. Note: Personally I was very concerned when I was unable to successfully format my card using the PSP. My thought process was that if the PSP is not able to successfully format the cards then it likely wouldn't be able to read/write data to them without issues either. This issue kept me from getting a successful build of a high capactity card for months as I searched and searched for adapters and MicroSD cards that would successfully format.

Next is lettering. Here I mean both font and verbiage. The font is very similar on most cards, though some have a slightly stronger/bolder printing that might help you distinguish between them. But, more visible are simply the words. Many will state "PhotoFast CR-5400" as highlighted by the blue rectangle (which they aren't). The rest will just print a generically more honest "MS Pro Duo" and "Dual Slot Adapter." Now - that being said, CSO compressed games are far from unplayable and in most cases won't have you twiddling your thumbs either. It is probably wise to stay with the name brands of memory (Sandisk, Transcend, PNY, etc.) And, since you won't necessarily see speed improvements with the newest and fastest cards you can probably buy the lower end of the more modern cards. Have some spare ones sitting around that are a few years old? They will probably work just fine. Alternately you can simply remove and replace the card. Some people believe that swapping cards while the PSP is on may lead to corruption of the filesystem on the card. While I have not personally experienced this, I tend to not remove my memory card while it is being accessed because I don't want to have to reformat and copy all my files again. However, do be sure to disconnect the USB mode from your PC before removing the card because that can lead to file system errors.

If you get a "Format completed." you are likely good to go - though you should read through the next sections to ensure that your card really is setup properly.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. There is a bit more detail below regarding FW versions (which are really beyond the scope of this guide). This is the latest and fastest API currently. It is most recommended for demanding less of your CPU, thus being the fastest. D3D11 ¶
