08.03.2008 (v1.90) : The night before the retro computer event
MadriSX 2008, improvements in the IRQ and VSync signals provide precise
synchronization (”Dragon’s Lair”, “Kat-Trap”), bugfixes in the FDC
support Titus’ disc protection scheme (”Wild Streets”, “Knight Force”)
and the Z80 search function and ZIP support have been improved as well.

The previous release of CPCE was made in a hurry and unfinished features were left out; this re-release gives LPTCPC the ability to send extended disc images (and it supports many copy protections) and improves the compatibility of the FDC reading commands, thus expanding the range of supported discs.
