Here some not documented functions of Mk6.

FREEZE Menu
===========

PARAMETERS (P)
--------------
Loads  parameter  file  from  disk  or tape. If the file begins with "T." - it
loads  from  tape,  but  if  the  file  begins with "E." - from disk device 8.
Example:  if  your  Action Replay ENHANCEMENT DISK in your drive 8, and if you
try  enter  "E.SS"  as  filename  you  loads  SCENE  STEALER prg (this program
enables  view,  find  & save freezed characters in memory). You may write some
parameter  files,  if  you think able to do this. Please notice, the parameter
file  not  need  any memory from your program and Mk6 saves it to hidden (Mk6)
memory location for later use (see Z hotkey above).

TURBO LINKER (L)
----------------
It  reenables  different  turbos  of  Mk6  by  changing  LOAD  ($330) and SAVE
($332)  vectors.  Here  some trick if prg crashes after running from FASTLOAD.
NORMAL  RESET  (F1  or  CTRL+RESET)  then FREEZE, TURBO LINKER, device(8), ANY
KEY, RESTART PROGRAM. After this 90% of programs runs well.

(Z)
---
This  key  you  can't  see  before  you  load any parameter file (if you load,
you  may  see  after  letter Z the name of parameter file (e.g. E.SS). You may
restart your parameter file without reloading it.


NOTE:  Did  you  know  how  to hack GEOS v1.3 and higher with Mk6? Its simple!
Boot  GEOS  &  start its CONFIGURE program.  Turn all drives off.  Now FREEZE,
BACKUP & SAVE. You have a working FREEZED copy of your GEOS.


UTILITIES Menu
==============

NOVA TRANSFER TO DISK
---------------------
This not function on Mk6. Find out it on Action Replay PARAMETER disk.


FASTLOAD turbos & interfaces
============================
The  FASTSAVE  &  DISKCOPY  uses  interleave 8. The WARP*25 uses interleave 2.
The  WARP*25  files  approx.  6% longer than normal files, because in one each
contain  240  bytes  (instead  of  254).  Disk  containing WARP*25 files can't
copied by normal DISKCOPY because WARP blocks marked with ERROR 23.

The  CENTRONICS  interface  emulates  channel  4  &  5 serial printers. If you
have  both  serial  &  centronics  printers  the  first have higher prior (use
ONLINE  of  printers  if  necessary).  Without  secondary  addr  your  printer
emulates  MPS801  characters.  But with secondary address 9 on CENTRONICS, you
opens transparent (native) mode of your printer.


FASTLOAD & TOOLKIT
==================

FASTLOAD commands
-----------------
%filename   - loads program as LOAD"filename",x,1:RUN
^filename   - loads program as LOAD"filename",x:RUN (bug in Mk's manual)

If  your  filename  in  save "*" your program will be save as unnamed (you may
not load it, but scratch it). The x means actual device.

Floppy commands
---------------
@=8 or @=9 - changes internal device number of actual device
@H:diskname,id - you may see changes after @I (bug in Mk7)
@R*=filename - makes your file unnamed
@S:filename  - deletes your WARP*25 file too (you not need specify it with ,W)

Different number notations under TOOLKIT
----------------------------------------
You may convert numbers in range of floating point number of BASIC. Try:
? $4E65DF,%101010101111110100110101010,&343245325254124

TOOLKIT commands
----------------
@K+ or @K-
Turns  on/off  FREEZE  TURBO.  FREEZE TURBO (by name) used automatically after
FREEZE.  Slower  as  normal  DISK  TURBO,  but don't blank screen and works in
all  memory  (TOOLKIT  default:off).  Never  turn on DISK TURBO in freeze mode
(it  kills  your  prg  area  $0000-$09FF).  The  TOOLKIT command OFF turns off
this turbo too.

@P"text"[:]code[;]...
Prints  a  text  or  control  code  (0-65535)  in  low-high  order.  Colon and
semicolon may be used as seperators.

@PLF
Turns off/on auto line feed for printer (default:off).

CBM
Dummy  command  (for  future  extensions).  In  early Mk-s it was ZAP command,
which RESET-s computer.

MONITOR commands
================
Before  numbers  the  "+"  prefix  means decimal numbers (0-255). You may also
use  words, if  you  enter  two "+" prefixed  numbers  in  High/Low  order. In
commands  "-"  sign  after  first  address means that command must work til it
memory ends ($FFFF).

*
Turns  between  RAM  and  ROM  configurations  (the  prompt  always  indicates
actual  mode).  In  FREEZE  you have doubled another memory area: $0000-$09FF.
In  this  mode  normal  prompt  indicates  your program area and revers prompt
the Mk6 work area.

@BR xx yy zz and @BR xx yy zz
In  FREEZE  you  may  view/modify diskblocks without any loose of your program
in memory if you turns mode * and use addr of buffer (zz) $09 ($0900).

@P or @MP or @BP
Functions as @P in TOOLKIT.

B
You  may  use  all  different  number  notations  and  BASIC  commands but nor
any TOOLKIT commands. Only first command recognizes.

S "filename",d,xxxx,yyyy,zzzz
If you want save $FFFF addr too, you must enter for yyyy the addr $0000.

Never  try  to  access  location  $DE00-$DEFF,  because internal configuration
register latch up by any read or write command.

---------------------------------
Some bugs noticed and fixed by me
=================================
1. In automatic line numbering mode after line numbers now you may see space.
2. Fixed @H bug.
3. Some function key layout & script changed.
4. After FREEZE+RESTART channel 3 of SID always disabled (now enabled).
5. Added feature SHIFT+RUN in FASTLOAD: LOADS & RUNS program.
6. Upgraded  the  ROM  with  32k  (on hacked version of Mk6).  Now it contains
menu  driven  user  defined  programs  called within TOOLKIT command CBM (like
TURBO-ASS, RE-ASS, SUPERCRUNCH, CRUELCRUNCH, etc.).

------------------
Interesting BUG???
------------------
Do  you  know  why  Action Replays don't work with SuperCPU turbo mode? Not? I
find  some  (LDT  $0000,y  ($BF)  illegal  opcode at offset addr $0F5C of Mk's
EPROM). Probably thats why!

maps, etc., please don't hesitate, contact me,
