The Sega Master System was the best one.

When I was looking into the local files for the ROMs, I found the Security Certificate; the file that contains the C64 version. I ran it on C64 Forever, the emulator I use, and I was shocked to find Summer Games 1 & 2, Winter Games, and World Games along with the game I bought. Are they supposed to be unlockable, or is this a mistake from the developers for this app?...

California games 2, Summer games, Winter games, World games, Impossible Mission, Jumpman Junior, Pitstop. Pleeeeeeeeeease? Too bad it isn't released as a package though, but better this then nothing.

How many Shared/Split Screen PvP players are supported? Does each person have the option to use their own controller?

Although sometimes after a practice the cursor moves a bit by itself. Also with some sports it's hard to figure out how to play it properly, https://apple2online.com/web_documents/california_games.pdf ?
