Changes
/* On MiST-board CoreAmstrad version */
'''prehistorik.dsk''' does run fine since r005.2 (key can now be pressed in intro demo)
'''Sim City''' and '''Hero Quest''' run fine since r005.2 (it was about "key always pressed"), but does need a hard boot (not quick reset keyboard key), certainly a small problem of component init state. '''Sim City''' hack demo intro does run better using A-Z80 instead of T80 (2/3 of luck).
A lot of demos don't pass in NEXYS4 FPGAmstrad's version (I need to implement back the SDRAM hacked in MiST board FPGAmstrad version). [http://cpcrulez.fr/Scene_Demos/index.php CPCRULES demos] is a cool ressource as it contains simple dsk formats.
