Changes
'''atomdriv.dsk''': unlocked since r004.5 (the game and music did freeze (ROM unplugged shall return xFF))
'''rtypeee.dsk''' : unlocked since r004.7. Does use special read FDC cmd, with BOT different of EOT (begin of track/end of track), so reading several 512 bytes blocks in one FDC command only.
'''Arkanoid Revenge of Doh''' and '''Asphalt''' are two games that doesn't support ROM extensions : Doh starts to show small bad layers, and Asphalt does crash and reset before main menu... if you add another gadget ROM.
'''saboteur2.dsk''': run fine since r005.5 (nice music and then freeze problem), it was about Yamaha clock generator (generated by Gatearray, versus WAIT_n added in short Z80 instruction to let them during all 4 clocks (Z80 in Amstrad does use 4T or 8T instructions (WAIT_n does insert missing T)).
