Reverse Engineer an Acid chip
Has anyone tried this? is it even possible?
Did you check the wiki - Amstrad Cartridge Identification Device - CPCWiki (http://www.cpcwiki.eu/index.php/ACID). That links to Verilog implementation of the ACID chip - CPCWiki (http://www.cpcwiki.eu/index.php/Verilog_implementation_of_the_ACID_chip)
