I've entered the codes needed to unlock the Tex and Rachel Support AIs, but I can't seem to use Tex.
Pressing left or right gives me 2 options:
DEFAULT, with pics of the default "Kumagoro" AI and another one I presume to be Tex.
RACHEL, with a pic of the Rachel AI
When I choose RACHEL, it clearly uses her in-game. But if I choose DEFAULT, it just uses the standard Kumagoro character. Anyone out there know how to use Tex?
In case anyone runs across this in the future:
Unless I entered it in wrong or something, it appears that the code for Tex only "kinda" works. After entering the code, I was able to see Tex next to Bill (Having used a Japanese FAQ, I listed him as kumagoro earlier), but it was under the default heading.
The game automatically uses Bill for Regular Mode and Tex for Extra Mode, and the code to unlock Tex just allows you to see him on the Support AI screen before you actually beat Regular mode, but is still only accessible during Regular mode until after you beat Extra mode. Beating Extra mode also allows you to use Bill in Extra Mode.
