This title has been converted from the PSP (PlayStation Portable) version to the PlayStation 4 and PlayStation 5 consoles and provides newly added features. Consequently, there may be times where the title plays differently from the PSP (PlayStation Portable) version, or where some features may cause the title to not function properly. This version does not support the PSP (PlayStation Portable) system’s peripherals, therefore some functionality may not be available.
