Post-nuke and others like it can be great if users didn't always just stick to the default stuff. I personally am extremely familiar with the code of Post-Nuke and have done wonders with it and have made tons of personal scripts for it that work great. I just finished convertng over
www.emulation64.com not to long ago and I run
www.psxfanatics.com that also uses post-nuke. It just depends on how much knowledge and effort you to put towards it that will make the difference.
