Functions
void	initMemCard (void)
	Starts libmcrd and sets up MEMCARD: the save file name and the section sizes.

void	setSaveFileName (void)

void	setSaveHeader (char title, CardClut clut, s32 count, void **icons)
	The save file header: title (Shift-JIS), icon CLUT and 1-3 icon frames.

s32	syncMemCard (void)
	MemCardSync, retrying a failed command up to maxRetries times.

s32	checkMemCard (s32 port)
	Checks whether a card is in port `port` (MemCardExist)

s32	acceptMemCard (s32 port)

s32	readSave (s32 port, void *buf, s32 size, s32 section)
	Reads a section of the save (SAVE_SECTION_*, then 2-4 for the data), a sector a call.

s32	writeSave (s32 port, void *buf, s32 size, s32 section)
	Writes a section (as readSave; section 0 takes the offset from bits 8 and up)
