Tempest and I talked about this before and I could never get WinVice to run my zipped roms either. I tried using MESS and was able to run in there. WinVice says it handles zip files but I haven't had any luck doing so. I haven't had time to troubleshoot it so will as soon as I get a chance. Another solution would be to make a script to temporarily unzip the file and then run and then delete after it closes.
