KR9600 Tester

The KR9600-PRO keyboard encoder has a bug of sorts.

So does the AY-5-3600-PRO keyboard encoder, according to page 7-12 of Understanding the Apple IIe by James Sather.

But despite being a drop-in replacement for the KR9600-PRO and AY-5-3600-PRO, the JCM-1 does not exhibit the aforementioned bug.  Well done!

Two-disk replica of Prince of Persia

A recent discussion of a buggy crack for Lords of Conquest raised the issue of preserving the original bits from protected software.

So I'm exploring a different approach -- instead of patching games to bypass copy-protection code (ie: 'cracking') why not devise methods of satisfying the copy-protection checks without patching the code?
