CF000000 00000000 (Code list end) | |||
Code used internally to specify the end of the cheat code list. It does not need to be specified manually. | |||
CF000001 xxxxxxxx (Relocate cheat engine) | |||
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. | |||
CF000002 xxxxxxxx (Hook address) | |||
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. | |||
C100000x yyyyyyyy (Call function with arguments) | |||
Call a function with between 0 and 4 arguments. The argument list follows this code, which has the parameters: | |||
* x - | * x - Number of arguments (0 - 4) | ||
* yyyyyyyy - Address of function | * yyyyyyyy - Address of function | ||

Run ARM or THUMB code stored in the cheat list: | |||
* x - 0 = ARM mode, 1 = THUMB mode | * x - 0 = ARM mode, 1 = THUMB mode | ||

| Line 66: | Line 68: | ||
AAAAAAAA BBBBBBBB | AAAAAAAA BBBBBBBB | ||
CCCCCCCC E12FFF1E | 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. | |||
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. | |||
Storing data at [offset+4] will save over the top of xxxxxxxx. | |||
C5000000 xxxxyyyy (Counter) | |||
Each time the cheat engine is executed, the counter is incremented by 1. | |||
If (counter & yyyy) == xxxx then execution status is set to true, else it is set to false. Based on Trainer Toolkit code. | |||
C6000000 xxxxxxxx (Store offset) | |||
Stores the offset register to the address xxxxxxxx. Based on Trainer Toolkit code | |||
D400000x yyyyyyyy (Dx Data operation) | |||
Performs the operation Data = Data ? yyyyyyyy where ? is determined by x as follows: | |||
C6000000 xxxxxxxx | * 0 - add | ||
* 1 - or | |||
* 2 - and | |||
* 3 - xor | |||
* 4 - logical shift left | |||
* 5 - logical shift right | |||
* 6 - rotate right | |||
* 7 - arithmetic shift right | |||
* 8 - multiply | |||
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. | |||

Nitro Hax is a cheat tool for official games running on the Nintendo DS. It supports any Action Replay DS code type with a few important additions.
The latest release is v0.94 with ongoing development on GitHub.
Installation
Download and extract file.
DLDI patch .nds file and copy it to the root directory of the card.
Place an Action Replay XML file on your media device.
User guide
Start NitroHax.nds from your media device. One of the following will be loaded automatically if it is found (in order of preference):
- cheats.xml in the current directory
- /NitroHax/cheats.xml
- /data/NitroHax/cheats.xml
- /cheats.xml
If no file is found, browse for and select a file to open. Remove your media device if you want to. Remove any card that is in Slot-1.
Insert the DS game into Slot-1, choose the cheats you want to enable.
Some cheats are enabled by default and others may be always on. This is specified in the XML file. When done, exit the cheat menu. The game will then start with cheats running.
Custom Code Types
In addition to the standard Action Replay DS code types described on EnHacklopedia's Action Replay DS page, Nitro Hax supports the following custom codes.
CF000000 00000000 (Code list end)
Code used internally to specify the end of the cheat code list. It does not need to be specified manually.
CF000001 xxxxxxxx (Relocate cheat engine)
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.
CF000002 xxxxxxxx (Hook address)
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.
C100000x yyyyyyyy (Call function with arguments)
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)
- yyyyyyyy - Address of function
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 C200000x yyyyyyyy (Run ARM/THUMB code)
Run ARM or THUMB code stored in the cheat list:
- x - 0 = ARM mode, 1 = THUMB mode
- yyyyyyyy - Length of function in bytes
For example:
C2000000 00000010 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.
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.
Storing data at [offset+4] will save over the top of xxxxxxxx.
C5000000 xxxxyyyy (Counter)
Each time the cheat engine is executed, the counter is incremented by 1.
If (counter & yyyy) == xxxx then execution status is set to true, else it is set to false. Based on Trainer Toolkit code.
C6000000 xxxxxxxx (Store offset)
Stores the offset register to the address xxxxxxxx. Based on Trainer Toolkit code
D400000x yyyyyyyy (Dx Data operation)
Performs the operation Data = Data ? yyyyyyyy where ? is determined by x as follows:
- 0 - add
- 1 - or
- 2 - and
- 3 - xor
- 4 - logical shift left
- 5 - logical shift right
- 6 - rotate right
- 7 - arithmetic shift right
- 8 - multiply
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.
Controls

B - Go up a folder or exit the cheat menu if at the top level
X - Enable all cheats in current folder
