I don't like the idea of modding my systems, so I've just imported a few games.
PS2: Swap Magic 3.something for the slim version of the PS2.
Tales of Destiny: Director's Cut
Phantasy Star Generation 1
Ouran High School Host Club
PSP: no region lock
Tales of Eternia (English version).
Tales of Destiny 2
DS: No region lock
Tales of Hearts
Yeah, I used to be quite the Tales junkie. Weirdly enough, I somewhat fallen out of love with the series. :S Most of my imports came from PlayAsia or Ebay.
My Japanese isn't too good, but I was so proud of my sister and myself for understanding enough to get through the first part of Phantasy Star without a GameFAQ! 8D I haven't finished it yet; I'll have to get back to it.
