Tales of the Tempest

Tales of the Tempest is the Sonic '06 of the Tales series: decent music, but a total trainwreck for everything else.

Debug Rooms
This game contains multiple debug rooms. These debug rooms can be accessed by swapping the respective ".mes" file with another. (Tip: "boot.mes" is the starting movie when starting a new game)

test1(?)
It contains an NPC which switches camera angles, with lots of NPC wandering. It has options for triggering random encounters, a teleport command which has the annoying side-effect of reverting your PC to Lv. 1, and some odd shops and chests. There are several other testing options.
