[DSK –flashing method-] 

 

This is the old method for loading DSKs. It has 
been replaced with the native support of Nextor 
for DSKs emulation. The new method will be used 
by default when loading a DSK from MultiMente. 
Check

 

[DSK from SD] 

for more information.

 

 
A DSK file is a disk image that contains the information 
of the sectors of a real disk. 
 
It is possible to load and run up to 9 disk images of 720 
KB.  These  files  can  be  loaded  and  changed 
independently.  It  is  not  necessary  to  previously  erase 
the  former  ones. 

Since  the  DSK  are  stored  on 

flashROM memory, they will be read only

 
In  order  to  load  a  DSK  you  must  use 

/D

  option, 

followed by the number of disk you want to select (from 
1 to 9) 
 
In example: 

OPFXSD 

undead.dsk

 /D1 

 

In  games  with  several  disks,  you  can  change  the  disk  
by  holding  the  desired  number  key  when  the  disk  is 
accessed (i.e.: after pressing space after a change disk 
dialog in a game) 
 
Pressing number 0 the disk access will be redirected to 
the next disk interface, probably the floppy disk. In this 
way you can save game data.
