CPCE 1.71´s main improvement is that the FDC handles 6 KB sectors, so disc protections used in "Double Dragon (Mastertronic)", "The Addams Family" and other games work correctly now. A pair of tiny bugfixes (overscan wrapping in DOS and hardware ports ghosting) allows Hermol´s "XMAS2006" intro to show despite a bug (the command at $8C3F should be LD BC,$BC00 instead of LD BC,$00BC).
