I have a love/hate feeling with Hyperspin, on the one hand I love the freedom it offers to create new themes, skins and incorporating new functionalities through Autohotkey scripts and using Action Script through swf files, but on the other hand, when I have all under control, I see that when launching it on Hyperspin, as dark13 rightly says, the results are not as expected and sometimes you go crazy to solve something that is already working.
I also believe that most of the current Hyperspin users do not play the games but rather enjoy improving their front end 😁
At the moment Launchbox is the one that is being updated... but honestly I prefer Hyperspin.
