Detecting CRC errors in .zip archives

[GoogleCodeExporter]

In main/rom.c, load_archive_rom() the .zip files are decompressed and 
opened.

The following function calls all return a status (which is not handled):
- unzGoToFirstFile(zipromfile);
- unzGetCurrentFileInfo(zipromfile, &fileinfo, szFileName, 255, szExtraField, 
255, szComment, 255);
- unzOpenCurrentFile(zipromfile);
- unzReadCurrentFile(zipromfile, localrom, *loadlength);
- unzCloseCurrentFile(zipromfile);

If the return value of any of these calls is < 0, my suggestion is that 
they are not added to the romdb. I know for sure that the unzReadCurrentFile 
return < 0 for one of my .zip archives with CRC error.
