I will be using Type-0 for reference.
I used the Steven Pboot, if you have problems where the game exits to livearea (after minis screen) use Steven's files.
1). Open Adrenaline EasyInstaller, advanced options, and Install Small Base game.
2). Press X to Reboot and enable Henkaku again.
3.) Open VitaShell, and navigate to UX0:pspemu/PSP/GAME/
4). Rename the NPEZ00104 folder to something easy to remember. I used FFTYPE000.
5). Navigate to UX0:pspemu/PSP/SAVEDATA/, create a new folder with the ID you created above (FFTYPE000), and Exit VitaShell.
6). Open Adrenaline Easy Installer, Advanced Options, and Update database (Don't use Rebuild!).
7). On your PC you need to Modify two of the .txt files downloaded from Qwik.
- 8). Copy all these files to UX0:pspemu/PSP/SAVEDATA/FFTYPE000/ (FTP or USB)
- 9). Copy these files to UX0:pspemu/PSP/GAME/FFTYPE000/ (FTP or USB)
NOTE: make sure The ISO file actually exists (ms0:/ISO/fft0.iso). I forgot to copy my ISO originally and got booted back to ARK, this is how I know it must be a path issue.
P.S. I have Kingdom hearts Birth By Sleep, and Type-0 working with plugins even, using this method. Hope I helped. Any other issues are probably related to Ark being incompatible, or maybe even the base game you choose.
