if you see this for loop, it will always loop until the end of the list is found,
ideally you'd stop once PHYSFS_ENUM_STOP was returned, (file was found)

for (size_t i = 0; i < fileList.size(); ++i)
			if(openReadEnumCB(data, dir, fileList[i].c_str()) == PHYSFS_ENUM_STOP)
				break;

this is likely why #246 has gone unnoticed.
