From Software made a few tweaks for the PSP version like ad-hoc play, data install to cut loading times down, and a way to use your data from Armored Core 3 Portable. Import your save file and you get 1/10 of the value of all your parts as credit.
Otherwise, Armored Core: Silent Line Portable is the same game Agetec released six years ago on a smaller screen.
