/*TODO:
--------
RESEARCH:
- See if shiny Pokemon from gen 2 can be square shinies or if they're all normal

LINK CABLE:
- Confirm JP Gen 2

INJECTION:
- Add in check for no valid Pokemon
- Combine the gen 3 data pointers into one class

GENERAL:
- Finish conditionals
- Restart the program after a transfer? Transfering twice without restarting corrupts the data (level included?)
- Finalize Graphics
- Simplify the sprite initalization
- Fade in and out
- Add in sound effects for pressing buttons
- Music
- Credits (List all programs, people, and code- plus TPCI)

FUTURE:
- Minigame
- Wii Channel
- Ditto Gift (Ignore Mew/Celebi?)
- MissingNo/Enigma Berry
- Text Translations
- Add support for other languages
--------
