It doesn't flock up if you replace the Zlib.dll. I did that and it still didn't work. I'll try it again when I go home. But I think the real problem is that some of my roms are not *.rom, but weirds ones with numbers in the extension. I tested my EGCG version out by placing just one rom that I know that has only *.rom files and it works fine. But if I set the directory to one that has more than it, it flocks up. But after Micro I'll try to replace the Zlib.dll with another older version. The romsets with lots of numbers are dumped directly from the home carts. EGCG doesn't support those for some odd reason, but 0.8c does. (and 0.6b etc)
