Someone who isn't me had an issue viewing a single .zobj until they opened a rom

error trace:

           _renderer.Memory.Segments[4] = F3DZEX.Memory.Segment.FromBytes("gameplay_keep", game.GetFileByName("gameplay_keep").Data);

It gave me the hint to suggest loading a rom before opening the zobj
And that worked

So there should be a check to not try to load gkeep if it's not available (no rom loaded)

Can't open a lone zobj properly without opening a rom first
