I was experiencing long load times, sketchy BGMs, voices and cutscenes, as well as whole sections of game terrain not loading during play. I use 1st class rated media for my backups so I'm not sure why this was happening. I also use SM 3.8 (CODER) and slide tool. Anyways, I stumbled upon Zoneloader, downloaded and burned it and so far my problems have dissapeared in Bully and GTA:SA backups...I've yet to test it with others. However, GTA still gives me the odd disc error or huge loading wait, but MUCH better than before. The point of this thread however was to ask if anyone can tell me how does Zoneloader work? What is it actually doing to make everything load better? Also, I have Zoneloader Beta 0.5, is there anything more recent? And that top Stickied thread regarding Media is awesome! Helped me figure out a lot of things about the media I'm using...which was getting real confusing as I live in Japan...for example, I bought some TDK and Mitsubishi DVD-Rs and using a media inspector I discovered that they were actually Taiyo Yudens and Verbatims...respectively. Guess I was lucky.
