Hello there, I have some questions regarding the PSTV. Doees anyone know if the PSTV is a valid option for speedrunning? Did anyone test it and compare it against PSP/PSvita? Do you know if there any difference in speed between store versions? Should I buy from US or JP store? Any other info is kindly appreciated.

I don't know specifically for this game but in general PSTV is the same speed as PSP/Vita, however disc changing is slightly slower. As for JP/US I am interested if there are any differences myself but after asking around I think they are just the same (For a speedrun).

From what I've seen of games/runs using the PSTV (ie MGS1, PE1) they always seem to run fastest on the PSTV... I know for a fact that the PSP runs poorly... not so sure about the Vita... as for which version runs fastest (NA/JPN) i don't know... I find that the controller configuration is much easier on the NA version then it is JPN though
