Problem extracting iso with 7zip

[icyqt]

Extremely new to emulators in general, i managed to get dolphin and paper mario ttyd working properly. I tried to download megaman and ssbm but every time i try to extract them after downloading the file on emuparadise, (i use 7zip) i get the "there will be some data at the end of the payload" then after it finishes extracting, i get "data error 'name of rom'". Then i do get an iso file but the file is always like 1/3 of a gb which is confusing because my paper mario file is like 1gb ish. I try to run it in dolphin and i just get disc cannot be read error.

Please help i have no freaking idea what im doing lmao

Are you using the latest version of 7zip from the official site? Should be v16.04 http://www.7-zip.org/download.html

yessir

Are you sure it was a complete download?

how do you tell if something was a complete download?

You can just check the file size on the download page with what you have, probably the simplest way. If for example it says 1.3gb and you end up with a file that's 450mb it's a clear bet it didn't finish

yes all the files i downloaded were the exact size that was listed on the emuparadise site

can you try this Download 7-zip Navigate to the file and extract.

Are you still getting the payload error when you extract with the latest build of 7-zip

Exactly what files do you have by the way? You should only be extracting one of the files as the rest are read automatically either first numbered part (e.g. *.r01 or *Part 01.rar) or if there is a rar file with r## files then the rar file is the first file and should be extracted from that file only

P.S. Wii games as well as GC games can be any size, there are Wii games under 100MB up to 9GB apx (GC games are up 1.2GB apx)
