Gamecube ISO problem

I've been wanting to get into Gamecube emulation and I've downloaded to games so far. The first was Megaman X Collection and the second was Zoids Battle Legends and they both have strange problems. Megaman was compressed into a rar file and when I decompressed it the game wasn't there, instead was a list of other programs with the games name and then .001 .002, etc. but there was another rar file that did have the game in it. Zoids also came like this, but the rar file with the actual game in it wasn't there like Megaman. Have I done something wrong? Sorry if this is a bit poorly worded, I had to type very quickly.

It's a split archive just choose extract here on 001 and it'll extract the whole thing from that and all the othher 002 003 etc.

It seems that I've run into another issue. When I try to boot the game it says,
"BackPatch - no support for operand size 1 Error encountered accessing emulated address c2339f3d
Culprit instruction: movzx eax, byte ptr ds:[rbx+rcx] at 0xfb0ab7c"
I have no idea what that means.

Which Dolphin version? Try disable the Panic Handlers, and if that's not working, try another version of the emulator (official or svn),

and, if that's not working again.. then the iso might be the issue.

It's the most recent one on the actual website.(3.5 I think) Disabling the Panic Handlers didn't work. I'll try another version but if that doesn't work then the iso probably is bad.
EDIT: I tried some other versions and they also don't work, it freezes on the screen that says, "Licensed by Nintendo". I'm going to stick with tthe conclusion that the iso is bad.

Before that, try running it on the official build, 3.0. IF that's not working, then you might want to try another copy of the game.
