I see a few things that could be updated
The European release of Dodonpachi Ressurection is not technically region free, as it won't play on a Japanese console. It was just made specifically to work on NTSC-U consoles.
For Espgaluda II Black Label, only the Standard Edition and Platinum Edition are region free, the Limited Edition is not.
A few I don't see on there:
Strike Witches Shirogane no Tsubasa (Region Locked)
Sakura Flamingo Archives (Region locked)
Game Centre Love - ~Plus Pengo!~ (Region Free)
Bullet Soul -INFINITE BURST- (Region Free)
Are you interested in documenting each individual release, or is just covering each game enough? (Example, Ginga Force and Eschatos had a dual-pack release). Also, do you think its worth noting physical, region-locked games that are still playable on other region's consoles (Example, Deathsmiles IIX is downloadable on the Games on Demand for US, but its retail version is locked).
Hopefully this helps a bit
