Why are games like Metal Slug 3 or King of Fighters 2000 not available for NGCD?
These two games are very big (688/708 MBits, respectively), so in order to put them on CD it would have been necessary to heavily cut them down which would have ruined the game completely. What’s more, the load times of such games would have been unbearable with their estimated 3+ minutes. What’s more, at the time when Metal Slug 3 and KoF2000 were released, SNK already was not well anymore, that’s why they cut any support for other systems than MVS and homecart.
