===On NEXYS4 version===
Games that doesn't run are :
*'''moktar.dsk prehistorik.dsk''': lag (key/joystick at begin demo... I cannot press lag)the key.
*'''aigle_d_or.dsk''': keyboard keys bad mapping evidence (pressing right arrow press also F3, then display "impossible" in this game in same time of moving, in fact it is not a joystick playable game) - this bug is located (some values appears double on keymap array)
*'''super_cauldron.dsk''': strange disk sector size evidence (not implemented yet)
*'''ACPC_logon_system.dsk''': text scrolling lag. This demo will be used for horizontal ink calibration (when I’ll buy a luxurious FPGA platform... I need in fact 224Ko of internal RAM to do it), and CRTC overcounts.
*'''atomic driver''': does freeze (problem of interrupt cycle ?), it is a really simple dsk format.
Arkanoid.dsk stars use rupture address (changing address several time during display of one image), it is now supported on "candidate 001" version of FPGAmstrad
Ghouls'n'Ghost.dsk / Ecole.dsk does need RAM write when writing in ROM (RAM is beside ROM, hard to emulate with asynchronous SDRAM controler, MiST does use a hacked synchronous RAM done for that)
moktar.dsk / super_cauldron.dsk does run fine since r004.8.1.1.
atomic driver does run fine since r004.7.2.
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.
