The root folder location for the Adrenaline stuff is
Also, remember that the "ux0:" part should be your mounted SD card if you are using SD2Vita.
By default, Adrenaline doesn't make the folders for anything. It just boots the 6.61 PSP CFW.
These are the folders you need to create inside the pspemu/ folder:
- ISO/ - You put your PSP .ISOs here. Also, you can create a folder called VIDEO inside this one for UMD Movies.
- seplugins/ - This is the folder where you put any PSP plugins you may want, like cwcheat.prx, npdrm_free.prx, nploader.prx etc.
- PSP/SAVEDATA/ - You put your PSP/PSX save data here. Pretty self-explanatory.
- PSP/GAME/ - You put your homebrew (like gpSP kai) or your EBOOT.PBP games here inside their respective folders (like PSX games and the like).
You can notice that pspemu/ is pretty much the root of the PSP memory card, so it follows the same structure that the PSP had.
