 In addition to the standard Action Replay DS code types described on [http://doc.kodewerx.org/hacking_nds.html#arcodetypes EnHacklopedia's Action Replay DS page], Nitro Hax supports the following custom codes.
-'''End of code list:'''
+ CF000000 00000000 (Code list end)
- CF000000 00000000
+Code used internally to specify the end of the cheat code list. It does not need to be specified manually.
-'''Relocate cheat engine to xxxxxxxx:'''
+ CF000001 xxxxxxxx (Relocate cheat engine)
- CF000001 xxxxxxxx
+Relocate the cheat engine to address xxxxxxxx. The cheat engine and all data are moved to the given address, which should be accessible from the ARM7.
-'''Change hook address to xxxxxxxx:'''
+ CF000002 xxxxxxxx (Hook address)
- CF000002 xxxxxxxx
+Change the hook address to xxxxxxxx. The hook should be a function pointer that is called regularly.
+By default the ARM7's VBlank interrupt handler is hooked. This code overrides the default.
-'''Call function with arguments:'''
+ C100000x yyyyyyyy (Call function with arguments)
- C100000x yyyyyyyy
+Call a function with between 0 and 4 arguments. The argument list follows this code, which has the parameters:
-* x - number of arguments (0 - 4)
+* x - Number of arguments (0 - 4)
 * yyyyyyyy - Address of function
-For example, to call a function at 0x02049A48, with the arguments r0 = 0x00000010, r1 = 0x134CBA9C, r2 = 0x12345678, you would use:
+For example, to call a function at 0x02049A48 with the three arguments r0 = 0x00000010, r1 = 0x134CBA9C, and r2 = 0x12345678, you would use:
   C1000003 02049A48
   00000010 134CBA9C
   12345678 00000000
-'''Run code from cheat list:'''
+ C200000x yyyyyyyy (Run ARM/THUMB code)
- C200000x yyyyyyyy
+Run ARM or THUMB code stored in the cheat list:
 * x - 0 = ARM mode, 1 = THUMB mode
-* yyyyyyyy - length of function in bytes
+* yyyyyyyy - Length of function in bytes
 For example:

   AAAAAAAA BBBBBBBB
   CCCCCCCC E12FFF1E
+This will run the code AAAAAAAA BBBBBBBB CCCCCCCC in ARM mode. The E12FFF1E (bx lr) is needed at the end to return to the cheat engine.
-This will run the code AAAAAAAA BBBBBBBB CCCCCCCC in ARM mode. The E12FFF1E (bx lr) is needed at the end to return to the cheat engine (These instructions are based on those written by kenobi).
+ C4000000 xxxxxxxx (Scratch space)
+Provide 4 bytes of scratch space to safely store data. Sets the offset register to point to the first word of this code.
-'''Safe data store (Based on Trainer Toolkit code):'''
+Storing data at [offset+4] will save over the top of xxxxxxxx.
- C4000000 xxxxxxxx
-* Sets the offset register to point to the first word of this code.
+ C5000000 xxxxyyyy (Counter)
-* Storing data at [offset+4] will save over the top of xxxxxxxx.
+Each time the cheat engine is executed, the counter is incremented by 1.
-'''Counter (Based on Trainer Toolkit code):'''
+If (counter & yyyy) == xxxx then execution status is set to true, else it is set to false. Based on Trainer Toolkit code.
- C5000000 xxxxyyyy
-* Each time the cheat engine is executed, the counter is incremented by 1.
+  C6000000 xxxxxxxx (Store offset)
-* If (counter & yyyy) == xxxx then execution status is set to true.
+Stores the offset register to the address xxxxxxxx. Based on Trainer Toolkit code
-* Else it is set to false.
+ D400000x yyyyyyyy (Dx Data operation)
-'''Store offset (Based on Trainer Toolkit code):'''
+Performs the operation Data = Data ? yyyyyyyy where ? is determined by x as follows:
-  C6000000 xxxxxxxx
+* 0 - add
-* Stores the offset register to [xxxxxxxx].
+* 1 - or
+* 2 - and
-'''Dx Data operation:'''
+* 3 - xor
- D400000x yyyyyyyy
+* 4 - logical shift left
-* Performs the operation Data = Data ? yyyyyyyy where ? is determined by x as follows:
+* 5 - logical shift right
-** 0 - add
+* 6 - rotate right
-** 1 - or
+* 7 - arithmetic shift right
-** 2 - and
+* 8 - multiply
-** 3 - xor
-** 4 - logical shift left
+For codes begining with 3-9 or A (if-type codes), the offset register can be used for address calculations. If the lowest bit of the code's address is set then the offset is added to the address. If the address is 0x00000000 then the offset is used instead.
-** 5 - logical shift right
-** 6 - rotate right
-** 7 - arithmetic shift right
-** 8 - multiply
-'''If-type codes:'''
-* Adds offset to the address if the lowest bit of the address is set.
-* Sets the address equal to offset if the original address is 0x00000000.
