Sky Smasher - bought this to work out if my existing board has a fault or not. It doesn't. Will be selling it as I don't need two. Try it in MAME, feels almost like a missing link between old and new when you come across one of the mid sized tanks that spew a continuous spread.

Fortress 2 Blue - it's sort of like Worms, with little military vehicles. The AI is dumb as rocks (on level 1 at least).

Donggul Donggul Haerong - very very weird Wonderboy clone with a pure Korean art style. It's a Crystal System motherboard with no case and the cart riser replaced with a ROM board.

The Alphax Z - bought it after trying Mission 660 in MAME which is supposed to be the same game. It isn't. 660 appears to be a revised version of this released in multiple regions, while Alphax Z is Japanese only. Unfortunately unlike 660, this version features heavy inertia.

Spiders - a bit like Galaxian with spider webs that slowly migrate down the screen.

Super Mario Brothers - yeah, what the fuck. It's like someone turned a NES into a PCB. The code is definitely based on the NES version, and the graphics output is kind of muddy and 'active', as if it's being turned back from composite into RGB. Adding weight to this theory is a board containing brightness and colour hue controls.

Hacha Mecha Fighter - something normal
