Changes
/* Tests done */
Others bugs are about dsk format, in fact a dsk is uncompressed into RAM at startup, so all dsk access are direct :
*ucpm format : normally it run, but in fact... it dondoesn't
*protected format : all format with sector size changed, and then no standards don't pass
*double side format : you can change disk and then reboot to insert it, so it's not done for changing disk while you are playing
