Yeah, this thing had an amazing library for having such a short lifespan. SNK vs. Capcom: Match of the Millennium and Metal Slug 2nd Mission are must haves, but as long as you avoid the gambling games, you're virtually guaranteed to pick up something that's at least decent. I'm going to recommend Biomotor Unitron and Faselei as good pickups. The former is a Pokemon inspired game about building a giant robot, and the latter is a strategy game with a frankly bizarre gameplay gimmick that works about 100 times better than it should. You have to put in all commands for your mech before a turn without any indication as to what your enemy is going to do beyond patterns you've observed. Somehow this made for a tense, strategic game with surprisingly little frustration.
