-gif maker-
Does anyone knows were i can find a free , no trial letters gif maker, i used one called jasc software but it expired, so i need a new one that can simply put images together and animate.......if anyone knows a link or a site, i would apreciate

-screenshot/movies-
so i have a dreamcast and not a computer, on a pc i can use fraps or similar programs to record movies and to take screenshots, unfortunatly i play in a dreamcast and the screenshots are pitiful and far away of being the bestquallity, not to mention it takes alot of memory,time and even a 2nd controler to do it.
is there a way to record it to my computer and take screenshots.
i found this guide on another site but i hate french and don't know 95 % of what's there

do i need just some cables and a program, or do i need to buy a specific part, cables and a program to make it work?

also note that i'm not sure if this is in the right forum....
