JP Practice ROM 1.4.2 Test 8 Changelog

JP Changelog: 1.4.2 Test 8

First JP Practice ROM. Uses the exact same code base as the US Practice ROM, so most things should behave exactly the same.

Disabled some features from the US practice ROM if the JP version is detected:
- File States (We don't have anything that would match up for the JP routes, so no point in this)
- Anything which involves phase tricks (No phase in JP, so no point):
	- Phase Assistant
	- D-Up to Auto-Phase
- The Info Card on the main menu (The font used for this uses the JP Character set. As such, it's not readable)
- The Practice ROM version on the main menu (see above)
- The following text changes (see above):
	- Wrinkly Hints
	- Main Menu alternate names
	- K. Lumsy copypasta text

Added "Enable Textbox Cancelling" cheat. Press B to cancel a textbox like you would with US/PAL
