You're looking at one of the ultratiny distros like Puppy. There aren't very many that will squeeze onto that small of a space so your choices are limited (which can be good and bad)
How much RAM do you have? And what are "simple" games?
Alright, this is it.
I run 2 virtual machines to run garrys mod so 3 clients at a time and wanted to save on ram. Because I use about 7g out of 8 when i run those 3. And windows xp uses 3gb or space. I was interested in linux and thought that it could help
The other computer has 2gb of ram as well and a pentium 4 @3ghz
I was thinking of Arch but it's hard. And puppy always has errors
Probably want to look at a Base or even a Core (if familiar enough with command line) Install of something like antiX-M11; TinyCore also lives up to its name and is simple to add what a person may want to add to it (although truthfully I do not know a thing about Wine).
