The only reason you'd see a size difference of 400% is because you're getting ROMs from the idiots over at edgeemu or somesuch that insist on sticking every last hacked-up copy of every game in existence into solid archives. Eg if you open the 7z file, you'll see multiple variations of the same game, where most of them are nothing more than minor sprite hacks and header byte changes.
Packing all of those images into one archive is asking for trouble anyway, as Snes9X has no way of letting you pick which one you want to actually load. And I really can't imagine why anyone would want the 13 header variations of Super Mario World that Cowering indexes.
Even in the most extreme cases, 7z should not be more than ~30-40% more effective than ZIP for single ROM, and if you have examples where it reaches >100%, please do share the image names and sizes you get, as I would love to compare for myself.
And lastly, if you are still worried about space, JMA is roughly as good as 7z. Certainly better than ZIP, and it's supported by most emulators.
comparing Zip to 7zip, when using ultra lmza compression, 7zip wins hands down, however since the size difference is in KB and not MB, does it really matter?
Well, in the even that you have hundreds and hundreds of roms, it can all add up.
I second the idea of having built-in 7zip support for Snes9x; It probably wouldn't be too hard because we could just integrate the un7z.dll.
Forgive me if I'm not thinking the right way... I just started learning how to use VisualC++.

What operating system are you using? 32 or 64bit? Version of Snes9x? Is the text at the bottom of the window white when you load the game?
