CTRPF-Action Replay Code Types

==============
INFO
==============
You have access to:
- 2 offset registers (not persistent)
- 2 data registers (not persistent)
- 2 storage registers (persistent)
persistent = register's value is kept between code execution
not persistent = register's value is set to default value when the code starts
Default value of offset (#1 and #2), data (#1 and #2) and storage (#1 and #2) registers is zero.
Default mode of all the registers is integer mode.
The active offset and data register is set to #1 when the code starts.
When a register index (#1 or #2) is not precised in the description, the active register is used.
====================
Shared Memory Page
====================
CTRPF creates an empty memory page at 0x01E81000 which allows you to
store and share values between your codes.
All of your codes have access to this memory range : 0x01E81000 - 0x01E82000
The way you use it is entirely up to you.
==============
CODE TYPES
==============
Memory Writes:
---------------
0XXXXXXX YYYYYYYY – 32bit write to [XXXXXXX + offset]
1XXXXXXX 0000YYYY – 16bit write to [XXXXXXX + offset]
2XXXXXXX 000000YY – 8bit write to [XXXXXXX + offset]
Conditional 32bit codes:
-------------------------
3XXXXXXX YYYYYYYY – Greater Than (YYYYYYYY > [XXXXXXX + offset])
4XXXXXXX YYYYYYYY – Less Than (YYYYYYYY < [XXXXXXX + offset])
5XXXXXXX YYYYYYYY – Equal To (YYYYYYYY == [XXXXXXX + offset])
6XXXXXXX YYYYYYYY – Not Equal To (YYYYYYYY != [XXXXXXX + offset])
Conditional 16bit codes:
-------------------------
7XXXXXXX ZZZZYYYY – Greater Than (YYYY > [XXXXXXX + offset] & ~ZZZZ)
8XXXXXXX ZZZZYYYY – Less Than (YYYY < [XXXXXXX + offset] & ~ZZZZ)
9XXXXXXX ZZZZYYYY – Equal To (YYYY == [XXXXXXX + offset] & ~ZZZZ)
AXXXXXXX ZZZZYYYY – Not Equal To (YYYY != [XXXXXXX + offset] & ~ZZZZ)
Conditional mode:
-----------------------
DFFFFFFF 00000000 - Conditional codes: value of address is compared to YYYY (immediate value)
DFFFFFFF 00000001 - Conditional codes: value of address is compared to active data register
DFFFFFFF 00000002 - Conditional codes: active data register is compared to YYYY (immediate value)
DFFFFFFF 00000003 - Conditional codes: active storage register is compared to YYYY (immediate value)
DFFFFFFF 00000004 - Conditional codes: active data register is compared to active storage register
Offset Codes:
--------------
BXXXXXXX 00000000 – offset = *(XXXXXXX + offset)
D3000000 XXXXXXXX – offset#1 = XXXXXXXX
D3000001 XXXXXXXX - offset#2 = XXXXXXXX
DC000000 XXXXXXXX – Adds a value to the current offset
Loop Codes:
------------
CX000000 YYYYYYYY – Execute next block YYYYYYYY times (immediate value)
C0000000 00000000 – Execute next block as many times as the value stored in data#1
C1000000 00000000 – Execute next block as many times as the value stored in data#2
D1000000 00000000 – Loop execute
D0000000 00000001 - Stops a loop execution directly (jump to next block) - Doesn't ends blocks
Terminators:
-------------
D0000000 00000000 – Ends a conditional block
D2000000 00000000 - Ends all block / Execute loops
D2000000 00000001 - Ends the code execution (ignore all blocks / next instructions). Doesn't ends blocks, so it can be conditional
Data Register Codes:
---------------------
D4000000 XXXXXXXX – Adds XXXXXXXX to the active data register
D4000001 XXXXXXXX – data#1 = data#1 + data#2 + XXXXXXXX

FYI: some your loop code info is slightly off. It should read as:

Loop Codes:
------------
C0000000 YYYYYYYY – Execute next block YYYYYYYY times (immediate value)
C1000000 00000000 – Execute next block as many times as the value stored in data#1
C2000000 00000000 – Execute next block as many times as the value stored in data#2
D1000000 00000000 – Loop execute
D0000000 00000001 - Stops a loop execution directly (jump to next block) - Doesn't ends blocks
