*sigh*....doesn't any one bother to read the tutorials these days?
I've only got two hands people--can only slap two at once!
What was that famous quote? "...so many a$$holes, so little time..."
Look, the basic copy protection is in the boot sector. This cannot be copied. That is why you need an alternative boot method that bypasses loading from this 2 minute pregap on your backup copy. Hence, the ModChip. There is an exception with some EA games and such that need to be patched because of specific "strings" of expected data that also may not get copied. This is usually done with PPF files. Tutorials and lists are available--if not here, on other forums/personal sites. Search for them.
Best, no brainer, stable solutions:
CloneCD properly configured for CD-Based PS2 Backups, with CD-RWIN and PPF-o-Matic for patching when necessary.
CloneCD compliant CD-Burner
PrassiPrimo/RecordNow MAX or DVDDecrypter and supported DVD-R burner for DVD based PS2 Backups. (DVD+R will work on some newer boxes, but only -R is proven success on older PS2's)
Alcohol and Nero products are also great tools and loved by many. They have become the defacto products for burning homebrews and RIPS. There are specific tutorials available for how to use these tools effectively as well.
All else is prone to problems that have been covered in various stickies and general postings. Look them up.
If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
