The DLC readme says that you'll need a "tool iso" to update the game and install the DLC, but that's only available on the real PSP.yes, usually you just need to move the folders to memstick/PSP/GAME
You are right that the ISO needs to be updated by the PSP.The DLC readme says that you'll need a "tool iso" to update the game and install the DLC, but that's only available on the real PSP.
Thank you for explanation.@GAMEman Upon investigating further it seems like it's not needed after all because v1.01 is an update of the Japanese version not the USA version.
Japan (has Update v1.01) > https://renascene.com/psp/info/umd/2391
USA (No updates) > https://renascene.com/psp/info/umd/2544
So you just copy the DLC the PSP/GAME/ and what DLC you get is everything that came out for the US version.
