At http://www.windows93.net/ , a parody windows OS, there is a version of SkiFree. However, im not sure if its emulation or made from scratch. Could mods look into this?

No idea how it's made, but it doesn't appear to be an actual copy of the game. Doesn't appear there is even a shalom or tree shalom option. Additionally, I was able to do some sliding while still on the falling sprite.
