I don't know exactly, but copyrights have quite a long lifespan, so those games won't be freeware for a while, also the company that made them doesn't show signs of wanting to get rid of them.
Those versions are hacks, they weren't made by capcom.
Please, proper grammar and spelling skills are appreciated.

Hacks usually allowed you to do weird stuff, like throwing fireballs while jumping and stuff like that. SFA2 doesn't work 'cause zsnes can't decompress its graphics on the fly, yet (or at least that is what I understand of this issue with SFA2 special chip) so in order to play it, you need the game's graphics pack and use them with zsnes.
Sadly I don't know where you can get them, but a google search could help.

there should be a pinned topic here somewhere with a link to the SFA2 grahics packs.
