Sorry about the lack of updates lately (more like the past 4 months), I'll try to be a little more active, especially now that I've got 3 weeks off from work (yay)

Here's the news for now...

Archery looks like a hack of Pooyan and the Skiing game is definitely a hack of Slalom. I saw something similar to this at a flea market here about a year ago, only the games had an Alien theme to them.

Thanks for the update!

Obstacle race is Zippy Race
Tunny is SonSon as the screen says
Without looking into it, I think Gold Digger is Door Door
Maybe Mars is Galg?

The ski game could be a race game.  My first thought was Rad Racer, but it's not quite right either...
