*'''rtypeee.dsk''': at begin of presentation, a draw of "jack plug" is done in a strange video mode, more than 200 pixels of height !, see [http://cpc.sylvestre.org/musee/musee_flipping_lace.html flipping lace]
*'''S&Koh.dsk''': LOGON SYSTEM, black screen in r005.8.4... damn
*'''Pinball_Dreams__PREVIEW.DSK''': really nice graphics and sound, but does freeze after several second of game in r005.8.4. Second test : Hard reset, do launch a Macadam game, quick-reset ("page up" key), launch pinball dreams... no freeze any more (certainly a CRTC1 detection failing). Third test : quick-reset after freeze, sometime it's fine, sometime it does freeze again.
'''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
