memory stick not showing?

[notori]

Hi, sorry if this is in the wrong place, but I'm having some problems with my game.

When I open up the rom in the emulator, it tells me that there's no memory stick inserted, the game takes 512kb of space, please inset a memory stick, etc. and it won't let me continue into the game without it where i can use savestates.

is this an issue with the rom or is there something i'm missing with the ppsspp memory stick?

(using windows 10)
