I'm not sure when sega released them to vita/vita tv but they are available in the PSN Store if anyone is interested in buying they cost quite a lot, i forgot the exact cost I think I used around 10k yen to buy all 3 games It feels a lot better playing it on vita/vita tv versus PSP (psp D pad is so bad), but the random fps lag stil persists even in the Vita port I'm hoping sega would port the dreamy theater variants to PS4 as well
