OMG! I didn't see the last posts! I have that trial demo too!
And... using a gameshark I can enter in debug rooms!!

Field --> ID
start 00
test 01
test1 02
test2 03
test3 04
test4 05
etc...

Triple Triad:
The background is different ("Exodus?") as forbidden's card, and elemental symbols.
Chocobo World:
Sun and cloud?. The present is totally different in final version. Cactuar is thinner in the trial.
