Lot's of HELP NEEDED

[InNeedOfHELP]

Thanks for reading this...
I have a Sonic 2 game that's real copy in normal(not japanese) so it works on my dc, I tried burnin a backup and the backup doesn't work, I tried using a "PPF ENGINE" and patching up 2 things into the CD Image and after it's burned it still doesn't work for some odd reason...I did use boot cd, and it makes weird noise for some reason...so am I patching it right or burning it right? When I patch it says it's not of same PPF or something...but I put patch anyways, do I patch it on to the CD Image? I don't understand this and also...What are "ISOS"? What do they stand for, what do they do? Why can't we ask for them...Thanks for your help...
