Black Tiger, I have some of the games you have.Actually, here are my impressions for all 20 games of mone.
Safari Hunting: brilliant scoring system and underrated
Girls Garden: fun arcade like title by creator of Sonic
Dragon Wang: I would likeit more, but no punching, and Jonathan is impossible to beat
Star Force: better than nes version
Sega Pitfall II: best platformer on system
The Castle: great game, but easy to get stuck
Lode Runner: timeless, better than nes version(you can see the whole screen)
Bank Panic: good port, good game
Sindbad Mystery: better than pacman, lots of strategy
Ninja Princess: great fun, about equal to The Ninja
Monaco Gp: best game ever made from the 1970s
Golgo 13: lame, only 3 stages
Champion Boxing: utter crap, but Pengo is in it

Drol: great computer port, original music is cute and catchy, like SonSon but has more heart

Champion Ice Hockey: fun every once in a while
Flicky: awesome platformer, smooth scrolling, no iggys!
Hustle Chumy: Compile should have made more platformers

Gulkave: incredible, best looking game on system, timeless, on My Card!!, horizontal
Wonder Boy: amazing effort, bizzare final stage, but should have been made on cart with more memory. Decent game
Hang on II: identical gameplay to Master system one, but has music!
EDIT: Star Jacker: a very simple shooter, but it is similar to Monaco Gp in it's franticness and excitement, along with a unique gimmick. A highlight of the very early SG-1000 games
EDIT: Chackn'Pop: I just got this game today for Christmas, and wow, am I impressed. I can only describe it as a gravity-warping Bomberman platformer of sorts, but it's an excellent game, a much better port than the NES version, and has that familiar Taito charm
Despite having a small library, the sg-1000 had a high quality to crap ratio, and there are still another 20 more games that I want for this system

Black Tiger, Team Pixelboy is porting and translating Black Onyx for Colecovision, so I can take your copy off ypur hands.
