* tabify a JSON file (not currently handled by srcclean) * get rid of stray printf * µ'nSP in header comments - we do UTF-8 source * spg2xx.cpp: make room for LOG_GENERAL - it's defined as (1U << 0) if you don't give it a different value * spg2xx.h: inline on member function declarations generally doesn't do anything useful - it's implicit when the function body is inlined at declaration, and in other cases you usually want to put the inline qualifier on the definition, not the declaration * rainbow.cpp: revert mouse changes - there's no reason a Mouse Systems driver couldn't be loaded, and the Logitech mouse is Microsoft-compatible * video21.cpp: use deal/stand for blackjack control buttons now that we're not using deal for vblank
