MiSTer FPGA Forum

Nevermind I had them in 7zip format.

edit: anybody know a good way to convert 7zip to .zip in linux?

Assuming that you want to convert the archives on a linux PC (and not in MiSTer), you can install p7zip which can handle both 7z and zip. If you want to do it in batch, see for example this script: Convert a batch of 7z files to zip.
