Cave Story (Doukutsu)
This is a repack of the Cave Story (Doukutsu) from RetroArch (Vita) v1.3.6, Other platforms of RetroArch the game comes included the files can be found in the libretro git (here) however I slimmed the files down in the included download with vpk. Simply follow the installation Instructions in the Installation tab.
Also, a tip as this libretro only plays this single game, you can make selecting the game each time a bit easier . View "Suggested Config" tab for more details on this tip
1.) Install "nxengine_libretro.vpk"
2.) Place "CaveStory_nxengine" folder in "ux0:/data/"
Since nxengine is only a game engine for Cave Story (Doukutsu),Lets set it up to launch the game faster and we will do that by making the ux0:/data/CaveStory_nxengine/ the default browser directory.
To do this, within the main menu navigate to:
Settings--> Directories---> File Browser Dir
Now navigate to:
ux0:/data/CaveStory_nxengine/ and select "<use this directory>'.
Now to load a game is much easier:
1.)Select" Load Content"
2.) Select "Select File"
3.) Now select: "Doukutsu,exe"
