SpudFiles

you can download chairgun pro for free from this site ->

clicky

IMO it's not as simple to use as chairgun 2 but there are a couple of changes that make it more useful for spudders, for example the max allowed projectile weight has increased to 12.96 g (in chairgun 2 the maximum was 5g)

I don't get why one would limit a certain input value on a simulator.
Sure, you can make the simulator give a warning, but restricting it? Whats the point of that?

I'll try it later. Nice find.
