When I put my 64 GB SDXC sd card into my memory stick pro duo adapter both bought from ebay and store videos and homebrew most of them work
but some games do not work though they turn up. I know the problem is with this combination as the games work on even a sandisk non adapter memory stick duo adapter. Do you know if it is possible to format it another way apart from formatting it through the psp? if there is a homebrew app for that?
