With this you can extract dsk images to files. Usage <nowiki>|</nowiki>dskx,"somedisk.dsk","/mypath" and all files are extracted to given path.<br /> CPC+ init. no longer clears screen.<br />Fix downloading files from the WEB UI.<br />Support 512KB cartridge images (mainly used by CPC+).<br />Added option in web interface to downgrade romboard to 16 roms, to be able to fit 512 KB cartridges.<br />Added option to upload & start cartridge images via web interface.<br />Set DHCP hostname to netbios name.<br />Fix crash when using run" without filename multiple times.<br />Improve timings of ROMDIS.<br />Only test IO bit 13 for rom selection (as CPC seems to do), was 0xDF<br />Fix Reset (clear rom state)<br />Change remote Reset, M4 reset & pause to acknowledge (IPC) commands or they could sometimes be ignored.<br />Updated ESP side SDK base to latest (v2.2.0), with whatever fixes that comes with it (ie. WPA/WPA2 vulnerability issue).<br />Fix Remote .sna for long filenames.<br />Fix for loaders using BE7D to restore drive letter (not checking if it is 00 00).<br />Change Amsdos workram 0-2 (ie. A700-A702) to 0 when using <nowiki>|</nowiki>SD and restore when using <nowiki>|</nowiki>DISC (only if AMSDOS or PARADOS present).<br />DSK: Do not show files with system attribute set.
