I am only the programmer, but I will give you a run down!! The only
programs on the page are, and will continue to be, programs made by members!
Programs such as X-Files 86, Magnify 86 &83, and many more soon to come such
as Picshift and Outwars(a starship troopers game!). Another facet is that
we make and convert programs upon request!!! You tell us what you need and
we will do our best to get it done!! ALL FOR FREE!!! We will also BETA
test, and let you beta test for us. The calcs we work with are the
82,83,85, & 86. We update often!!!
