BIOS font hacks

These are hacked BIOS with a 8x16 latin font stored inside 16x16 SJIS Kanji tiles.

It allows to store 2x ASCII chars using a valid 16bit SJIS encoding.

It is easier to use than SYSCARD_Translatefont, since you do not need to patch any text rendering routine, you only have to encode the text correctly (table file).
