hello there! just wanted to ask, since I've tried to search for the answer, but haven't had much luck. I haven't updated since 0.168, but I think that it's time. my CHD's that I have are in winzip format. can I convert them to 7-zip format to save a little hard drive space, and will MAME still recognize them? I don't know the compression ratios, but I understand that 7-zip is much more of a space saver. I know that getting a larger hard drive is the easiest solution, but my rig won't accept anything larger than what I already have. might be time to just break down and upgrade. I dunno. but for the time being, I need to save some hard drive space if I can. any help at all would be much appreciated. thanks in advance!!!!
