People have to speak with their wallets though, that's the problem. Nintendo can release rom dumps and people will still buy them. What incentive do they have to add online functionality, leader boards, etc. to their old VC games? From an profit:effort ratio, Nintendo is crushing Microsoft. The amount of work put into some of the XBLA releases is ridiculous compared to just dumping a rom, droppin some DRM on it and selling it as is. Castlevania for example, remaking the entire game from original assets? Updating textures for other games? etc. etc.
