There are only 2 ways i would buy/ play these versions is if:
1There was a hard mode i.e. Eniamys had more HP and things cost more.
2 updated grafics and when you completed the game got the orriginal unlocked.

Squre-enix should take time on this and bring these to us in a new way insted of a DOS port/uptate
P.S i can get GBA/SNES/NES emulaters for the psp anyway so they should take there time :fencing: :shoot:
