I'm not too familiar with the NEO・GEO era. What titles deserve to be here?

https://en.wikipedia.org/wiki/List_of_Neo_Geo_games

Crystalis.

...And that's about it, because SNK isn't my jam.

Power Instinct Matrimelee and Neo Turf Masters.

Bang Bead, Battle Flip Shot, Eight Man, Galaxy Fight, Last Resort, League Bowling, Magician Lord, Metal Slug 4, Metal Slug 5, Neo Bomberman, Neo Turf Masters, Ninja Master's [sic], Pulstar, Puzzle Bobble, Puzzle Bobble 2, Spinmaster, Super Baseball 2020, Top Hunter: Roddy & Cathy, Windjammers.

Maybe Burning Fight too for that extra cheesy beat 'em up fun.

I don't know, lets have a look at all the other stores which already have them available - apparently badly emulated from what others have said - and then we can look at bring them in in say 1 or 2 years to a standing ovation?

They have Shock Troopers which is all I need. Love that game. :D

Competently coded ones or nothing.

This.

If you just ship emulation packages, at least use good ones.

Garou - Mark of the Wolves! :D

Honestly ? None .

Fast Striker, Gunlord and Neo XYX

Garou Mark of the Wolves
Real Bout Fatal Fury series
Rage of the Dragons
Power Instinct Matrimelee
Neo Turf Masters
Art of Fighting series
Sengoku series
Nightmare in the Dark
Blue's Journey
Breakers Revenge (Updated version of Breakers)
Crossed Swords
Last Blade 2
Samurai Shodown 4
SVC Chaos: SNK vs Capcom
Waku Waku 7
Kizuna Encounter

It may be a lot but those are great NeoGeo games that i totally recommend. I could name King of Fighters series but then it'd be too much (KoF 2001 is meh though)

Add samurai shodown 1 and 3 to your list and I'll agree, except for SVC, that game was kinda crap.

Fallout New Vegas

I would like to see all of the KoF games and Metal Slug 5 or 6. Whichever ones has the PC ports.
