Dissidia 012 Duodecim Final Fantasy texture problem

1.Does the Jpcsp Launcher change only 32bit Jpcsp and not 64bit (cause I use 64bit)?

There is several ways to use the 64bit jpcsp with the launcher
Simply extract the 64bit Jpcsp archive from the buildbot then put the launcher in the top level dir where the bat files are, run the launcher, it should auto select 64bit, Don't forget you will need the 64bit Java runtime installed.
