I don't know 'bout your friend, but I'm just starting out with actionscript, and the first thing i learned (well... almost first...) was a method that creates an encrypted file, that can contain any variables you want... It is flash MX though, don't know if that matters...
I was planning on making a flash frontend for my cab, but then remembered I'm lazy, and decided to go with MAMEWAH...
Wait a second! Are you talking about a frontend made
with flash, or a frontend
for flash???
Now I'm confused! Anyway, a frontend
for flash, is no problem... Most frontends should easily open up a flash file... Wether it's .swf (in which case it'll open the default "handler" for that on your OS), or .exe (which you can make with a program that comes with flash...), you can easily configure most frontends to work with flash...
Hope my post ain't stupid!
