zip, 7z support for natively opening in editor?

[Geezgus]

The editor already supports opening archives. Is there any way to standardize a file format (like GB7, GBZ, etc.) so these can be assigned to the emulator?

mGBA will always try opening the selected file as an archive before trying to open it as a ROM. It doesn't use the file extension to make any decisions. If you want this, you can associate .gbz files with mGBA using Windows settings and it should just work.
