New F6 Cheat Type (IF,ELSE IF, ELSE structure)
Cheat Type F6 lets you perform cheats in IF / ELSE IF / ELSE constructs along 
with multiple conditions for each one.

It supports conditions  D0, D1, D2, D3, E0, E1, E2, E3, A0, A1, A2, A3, D7 and 
two new types that will only be available in the F6 conditions :- 
E4 & E5 which are bit comparisons on bytes (set and clear). 

Any of those types which are "block conditionals" like D7 will be treated as a 
single condition with the other conditions so you wont need to worry about 
extra 00000000 FFFFs just for them (infact you can drop them completely apart
from the last 00000000 FFFF, which you can also drop if you have no trailing
cheat lines after the end of the construct.


#IF / ELSE IF / ELSE Statement Example with Notes
80001000 00000001   Setup Test Condition 1
80001004 00000002   Setup Test Condition 2
80001008 00000003   Setup Test Condition 3
8000100C 00000004   Setup Test Condition 4

                    1F = IF, last two digits determine the number of conditions to check
                    F600000x  x = 0 All conditions must be true, x = 1 At least One condition must be true                  
F6000000 1F000004   Check the next 4 lines as the conditions for the IF loop to be taken

00000000 0000FFFF  End of IF Statement

F6000000 E15E1F02  E15E1F = ELSE IF (same format as IF) - Can have multiple ELSE IF Blocks or none at all

F6000000 E15E0000  E15E = ELSE (no need for conditions - this will poke if the others dont)
80001010 0000AAAA    Poke(s)

Updated chtdb.txt and added new types F5, 52 & 53. Cleaned up type 51
Chtdb.txt
=========
Updated the header to document all the new cheat types, added some more cheats
and cleaned up others.

New Cheat Types:-
=================
F5 - 16-Bit toggle cheat, predominatly used with the D7 cheat to enable/disable
      ASM cheats with the same key presses. See chtdb.txt for more information.

52 - Register Block Conditionals for use with the type 51 cheats. There are 128 
      sub types. See chtdb.txt for more information.
      
53 - Improved Slide Code cheat type, with support for 65536 addresses and a 16
      bit step and easily configurable step direction for value and address.
      See chtdb.txt for more information.      

Other Changes:-
===============
51 - Cleaned up - renumbered/renamed, Tested & Bugfixed. See chtdb.txt for more 
      information.

PugsyMAME 74b2b2ddfe
Added new cheat cheat types: C3, C4, C5, C6, D7&52
C3-C7 are variants of C0
D7 is a BIT based joker to rule them all. It includes the analog sticks (@ggrtk thanks for adding the analog reading capability). Also added the facility of making dual single key joker by varying the amount of time a button is held down.
51 is a complicated beast that I still need to document

* C3XXXXXX 00YY - 8-Bit Master Code, if ($XXXXXX) is less than 0xYY poke all
  00000000 FFFF       following codes for rest of the cheat or until it reaches the
                      00000000 FFFF line.
* C4XXXXXX 00YY - 8-Bit Master Code, if ($XXXXXX) is greater than 0xYY poke all
  00000000 FFFF       following codes for rest of the cheat or until it reaches the
                      00000000 FFFF line.
* C5XXXXXX YYYY - 16-Bit Master Code, if ($XXXXXX) is less than 0xYYYY poke all
  00000000 FFFF       following codes for rest of the cheat or until it reaches the
                      00000000 FFFF line.
* C6XXXXXX YYYY - 16-Bit Master Code, if ($XXXXXX) is greater than 0xYYYY poke all
  00000000 FFFF       following codes for rest of the cheat or until it reaches the
                      00000000 FFFF line.
* D7PQRRRR TTYYYYYY - 24-Bit Universal BIT Joker, OR the hex values to
                     combine into a multi-button joker. Because it is BIT
                     based it is better than D4, D5, D6 or using a D0 joker as you
                     do not need to worry about any other buttons being
                     pressed at the same time and you get both analog
                     sticks for extra functionality. Note if you want to use it
                     just as a enhanced joker just use D7000000 00YYYYYY when
                     the buttons/directions are pressed or D7100000 00YYYYYY
                     when you want to ensure they are not all pressed.
                     QRRRR TT provides the capability of only activating the
                     following codes after the keys have been held in for a set
                     amount of frames. 003C = 60 Frames = 1 Second at 100% Speed
                        YYYYYY = 000001 L2 Button
                        YYYYYY = 000002 R2 Button

                        YYYYYY = 000400 R3 Button
                        YYYYYY = 000800 Start Button
                        YYYYYY = 001000 Up (Digital)
                        YYYYYY = 002000 Right (Digital)
                        YYYYYY = 004000 Down (Digital)
                        YYYYYY = 008000 Left (Digital)
                        YYYYYY = 010000 Up (Right Thumb)
                        YYYYYY = 020000 Right (Right Thumb)
                        YYYYYY = 040000 Down (Right Thumb)
                        YYYYYY = 080000 Left (Right Thumb)
                        YYYYYY = 100000 Up (Left Thumb)
                        YYYYYY = 200000 Right (Left Thumb)
                        YYYYYY = 400000 Down (Left Thumb)
                        YYYYYY = 800000 Left (Left Thumb)
                      NOTE: The 0s in the code are reserved for possible
                            future use.
                       TT=Temp Internal Variable 00-FF, 00 will mean it wont be
                            used, if it's not 00 do not use the same value for
                            jokers using different keypress combinations for
                            the same game.
                       P = 0 or 1. 0 = Check ALL YYYYYY Bits are ON
                                   1 = Check ALL YYYYYY Bits are OFF
                       Q = Frame Comparison 0 = Dont do any comparison
                                            1 = Check that the button combination
                                                has been held down for exactly
                                                RRRR frames.
                                            2 = Check that the button combination
                                                has been held down for more than
                                                RRRR frames.
                                            3 = Check that the button combination
                                                has been held down for less than
                                                RRRR frames.
                                            4 = Check that the button combination
                                                has been held down for anything
                                                but RRRR frames.
                       RRRR = 0000 to FFFF, Frame Comparison Value
                      It will then poke all following codes for rest of cheat
  00000000 FFFF       or until it reaches the 00000000 FFFF line.
