Ok I started testing load time and I found that the .zip and the .rar only work one time after that the error returns if you then delete it and make a new .zip or .rar that works one time and then breaks again 7z work every time.
My load time test results were
7z with the file located on my local computer 23 count
.rar on the local computer 8 count (but only worked once)
.cue from my network server instantly
.cue locally also instantly
.zip locally about 10 count (only works once)
The .cue/.bin combo is around 730,000kb while the .zip is 365,000kb, .7z is 300,000kb and the .rar is around 330,500 so yeah you save a ton of space using the compressed files but you sacrifice at least so far load time I don't know how it will effect performance.
Did more testing after typing the 1st part of this and this is what happens if you launch the .zip and the .rar files the temp files deletes when you exit the emulator if you launch the .7zip it doesn't delete if you then launch the .zip or the .rar file without manually deleting the temp file 1st they no longer work even if you delete the file manually afterwards they both stop working if you do delete it then they both keep working. The .7z file works over and over again even though the temp file is not deleted. So basically if you load the .7z file and let it load completely when you close out of the emulator then the temp file doesn't disappear and it breaks the other files for some reason. Now I don't know if closing LB and restarting it then the files would work again and they aren't actaully broken but LB won't work with them until restarted.
