Release id #41156 : DTV kernal V0.2

README for Peiselulli's Kernal 0.2
----------------------------------

"Peiselulli's Kernal" is a kernal that adds some new features to the DTV Kernal.
It is only tested with a PAL DTV (DTV3).

There are two versions included in this zip file:

Kernal.prg   : this kernal stays at 0x1fd200-0x200000 in RAM and a hook
               is installed at 0x018000-0x018100 in RAM to make it possible to
               execute it while pressing the left joystick button after
               releasing reset. First start simply with "run"

Kernal.flash : this kernal is for flashing it at 0x1fd200-0x200000 in flash.
               It can be run with DTVMON/DTVBOOT 0.7 or higher installed.
               See "http://www.kahlin.net/daniel/dtv/dtvmon.php" for more
               details.
               FLASH IT ONLY IF YOU KNOW WHAT YOU ARE DOING !!!
               
Both kernals use 0x1f8000-0x1fc000 in RAM while saving or loading.

Features:
    - fast load : based on "dtv speed load" (thanks to TLR !)
                  25x load speed, but works only with device 8 !
                  Only tested with 1541 (I + II).
                  loads everything into ram under the roms and the IO.
                  can load 254 block programs !
    - fast save : based on hypra-save (??)
                  (don't know how fast is it compared to original)
                  works with any device.
                  Only tested with 1541 (I + II).
                  saves everything from ram under the roms and the IO.
                  can save 254 block programs !
    - list directory from disk without loosing loaded programs.
                  replaces "PRG" with ",8,1" for easier loading (see function
                  keys)
    - list the *REAL* content of the flash directory.
                  The format of each content is the following:
             <loading start address> "<name>",1,1:<flash start address in hex> 
    - default device from basic is 8, not 1
    - "load" without filename loads the directory of device 8
    - "save" prompts with a small dialog to enter the filename if no parameter
                  is given.
                  This is very useful for saving large files without getting
                  the infamous "out of memory" error because basic cannot store
                  the filename. The filename is stored on the stack.
    - function keys:
            F1 : list directory in empty line, loads a program if a filename is
                 following. Easy to used with listed directories 
                 (try it and you understand it what I mean).
            F2 : run
            F3 : sys 4096* 8 (cursor is placed on the "8" to edit)
            F4 : save
            F5 : submit a floppy command
            F6 : read floppy status
            F8 : list
     - shift+run/stop (=esc) starts the first program on drive 8
     - loading and saving addresses are printed in hex

============================================================
Changelog:

V0.2 :
        printing loading and saving addresses is added
V0.1 :
        initial version

============================================================
            
Have fun ...
