So, I've drummed up the following games:
Alien Crush
Cosmic Fantasy 2
Dragon Spirit
Dungeon Explorer
Exile
Final Lap Twin
J.J. and Jeff
Keith Courage in Alpha Zones
The Legendary Axe
The Legendary Axe 2
Night Creatures
Ninja Spirit
Order of the Griffon
Psychosis
Sidearms
Sinistron
Valis 2
Valis 3
Victory Run
Ys Book 1 & 2
Ys 3: Wanderers from Ys
Night Creatures, Exile, and the two Valises have not arrived yet.
Some first impressions from the ones I've tried:
Alien Crush: Love the graphics. Definitely a lot moodier than the cover would make you think. The actual game seemed okay.
Dragon Spirit: Vertical shooter, probably closer to the arcade than the NES version.
Keith Courage in Alpha Zones: The controls seemed awkward and the level design bland.
Legendary Axe: I don't think many of you have played Astyanax so this analogy is probably lost, but Legendary Axe is pretty much a 16-bit version of it with better controls.
Legendary Axe 2: How could anybody have any clue what the plot of this game is just by watching the opening cinema?
Ninja Spirit: The first level was boring as all hell, and I didn't even die once. In fact, I didn't die until I got to the second boss, an old ninja who kills you in one hit.
Order of the Griffon: I find it incredibly lame that the battles have no music, and that those battles are the kind where everyone freaking misses all the time.
Psychosis: Horizontal shooter with graphics that were spawned by narcotics. It's not that the color schemes are offensive - far from it in fact. It's that the enemies are things like strings of giant cooked shrimp in bubbles. The cover art is also pretty screwed up.
Sidearms: Horizontal shooter where you can fire left and right. Pretty fast paced.
Sinistron: This is supposed to be R-Type lite, except the pods seem to just be there for you to ram into enemies, and a powerup lets you widen your firing range.
Ys Book 1 and 2: Working Hydlide.
Ys 3: The mine song no longer sounds like somebody farting through a horn! Hooray!
