I got a bunch of new SG-1000 games today, that I tested on the Master System. I got them directly
from Japan, but customs noticed and I had to pay a hefty import tax. I'm not sure I would recommend their services, I'm not even sure they're cheaper than buyee with additional fees everywhere.
Pitfall II was one of my white whale, and it seems to hold up to my expectations. It is said to be quite different from 2600
Pitfall II: I don't know about that, but I liked what I played. My tower of power kept freezing so I couldn't go very far. Bonus points, it's entirely playable with the SMS colour palette, there is no black enemies on dark green background like in Ninja Princess.
H.E.R.O is the second Activision game I received, and quite a quality port too! I would argue that it's the best looking port, and also the most badass as the protagonist is now a rocket-man instead of a wimpy helicopter-man. Like
Pitfall II, the game is completely playable on the Master System.
Bombjack is a bonus, and while the graphics ar quite crude compared to the arcade and some later computer ports, it plays nicely. I still think the Amstrad CPC port is the better of the 8bits systems, but this SG-1000 version has nothing to be ashamed of (ok, maybe the bomb sprite). The Master System palette clashes with the gameplay sometimes, but it's still playable. I am of the opinion that
Bombjack could be made arcade-perfect on the Master System, but no one has tried yet.
Dragon Wang is the last game of the bundle, and I don't like it. Terrible controls, terrible design, not really pretty. I could have forgiven the controls and visuals if it was actually playable and enjoyable, but I don't think there is much to redeem in this game. Sorry Wang.
They are all card games, which means you can play them on a western Master System if you mod it to bypass the BIOS. Or with an Everdrive, whatever.
