Re: Gemdos + desktop for lisa

this version may work on 1.5Mb
I added a new command to command.prg to set value of video base register. type MAGIC and the screen should appear.

It will not fix the issue on 512Mb because the base OS is hardcoded to 1Mb in gemdos and I do not have the full sources to compile A proper lisa MMU initialisation is needed but it may be a better and faster option to port emutos to lisa.

There are also debug logs on the init command. here again the problem seems to be in gemdos.
