Hey i just bought this one SanDisk Ultra 64GB microSDXC... https://www.amazon.com/dp/B010Q588D4?ref=ppx_pop_mob_ap_share and the memory stick here PSP Memory Stick Adapter,... https://www.amazon.com/dp/B07F68FCHD?ref=ppx_pop_mob_ap_share and they work edit: i too have a psp1000

The PSP Go has internal storage, but all the others need a memory card. It's really common to buy a micro SD and a MicroSD-to-MSProDuo adapter (something like this).

According to Amazon, I bought one or more of these back in October, and evidently it hasn't failed on me yet. :)

No, that’s an adapter to plug into your computer you’ll need this one for it to work on psp

You should look after memory stick micro sd adapter (like https://www.amazon.com/Memory-Adapter-Converter-CR-5400-CR5400/dp/B075DDGYVG/ref=sr\_1\_1?crid=133BCP4M3CY96&keywords=cr+5400&qid=1667244498&sprefix=cr+5400%2Caps%2C335&sr=8-1 with dual micro sd capability or https://www.amazon.com/Funturbo-MagicGate-Playstation-Portable-Handycam/dp/B07F68FCHD/ref=pd\_bxgy\_img\_sccl\_1/131-8427508-7635323?pd\_rd\_w=bwwgt&content-id=amzn1.sym.7757a8b5-874e-4a67-9d85-54ed32f01737&pf\_rd\_p=7757a8b5-874e-4a67-9d85-54ed32f01737&pf\_rd\_r=SY0V0T7CVRX12KA3NY3M&pd\_rd\_wg=LUaxt&pd\_rd\_r=77d514b0-029d-4686-9c00-e300f525acc1&pd\_rd\_i=B07F68FCHD&psc=1) or if you want be truly psp fan just find memory stick pro duo from Sandisk or maybe even from sony

It takes a Memory Stick Pro Duo, but it's really common to use a Micro SD in an adapter like this one.

If you're going to use Custom FirmWare (CFW) to run games from the memory card, 32GB gives you the space for roughly 30 PSP games. If you're running purely from UMDs, you'll never use all that space, but a few games (like Peace Walker and Birth By Sleep) want to install a bunch of cache data, so having a few GB of space is a good idea.
