I’ve updated cdb-util (formerly makecdb) to support extracting text cheats from CDB files. CDB (CheatDataBase) is the format used by Cheat Device for storing its cheat database (as the name implies ūüôā ). A few users requested a way to extract cheats from existing CDB files so I figured it would be a useful addition.

Microcontrollers are the heart of many DIY projects, but there are some situations where a CPLD or FPGA is more appropriate.¬†There are many development boards available from Terasic, but I wanted to try something different. I’ve heard “no-name Chinese FPGA boards” can often be more trouble than their worth, but I decided to take a chance with a rather inexpensive CPLD one.

C-M240 Development Board from EDA Board

C-M240 Development Board from EDA Board

This is a¬†fairly bare bones Altera MAX II development board from a seller on AliExpress named “EDA Board”. It took over 5 weeks to arrive, so I wouldn’t recommend purchasing this if you want to work with it any time soon.¬†It’s a good deal for the price as most similarly-priced development boards are merely breakout boards without any on-board components.¬†This board has two 4×7 digit LED displays, eight LEDs, five input buttons, a buzzer, and unpopulated breakout pins for the remaining¬†pins on the MAX II. It comes with a USB Blaster clone and power cables too! Unfortunately there are no schematics availble and contacting the seller has proven to be difficult, but I determined the¬†pins used by the LED displays to be as follows:

Pin Description CPLD Pin
A 85
B 84
C 83
D 82
E 81
F 78
G 77
Decimal 76
D1 95 (left), 89 (right)
D2 92 (left), 96 (right)
D3 91 (left), 86 (right)
D4 97 (left), 85 (right)

The silkscreen lists the pins used by the LEDs, buttons, and buzzer on the board, but the 4th LED from the bottom incorrectly says “PIN_55” when it’s really pin 54. My board also had a zero ohm resistor across the “on” pins instead of a power switch as shown in the item pictures.

Putting these minor inconveniences aside, I think this board will be good for simple CPLD projects. However, I’ll probably stick with something from Terasic if I wanted to work with a Cyclone FPGA in the future.

I started work on this in October of last year, and after a few months of working on it on-and-off, I released the first version in April. It’s a sequel of sorts to my previous PS2 cheat device project, but I wanted to make something from scratch. The code got gnarly on the old menu so I decided to discontinue working on it and create this. Maybe I’ll move on from PS2 stuff some day, who knows :-).
Cheat Device is a game enhancer for PlayStation 2 games, similar to Action Replay, GameShark, and CodeBreaker. It supports booting retail, disc based games as well as ELF files such as OpenPS2Loader or ESR.


  • Easy to navigate menu system similar to CodeBreaker
  • Supports retail discs and loader ELFs
  • Fast loading of large cheat lists
  • Save manager for backing up and restoring game saves to/from a flash drive
  • Powered by ps2rd’s powerful cheat engine

Important Things
Storing Cheats
Cheat databases are stored in CDB files created with cdb-util, which will convert cheat lists following this simple format:

"Game Name"
90000000 88888888
Cheat 1
27654321 12345678
Cheat 2
12345678 98765432
Cheat Section
Cheat 3
11111111 00000000

Enable Codes
9-type enable codes (9xxxxxxx yyyyyyyy) are supported, and the first cheat for every game must contain an enable code. If an F-type enable code is used instead (which is common for older games), it will be silently ignored and a hook will be installed automatically by the code engine. Many games have been tested with the auto-hook function, but its best if a 9-type enable code is used.

Code Format
All cheats must be in “RAW” format; Cheat Device can’t decrypt or read any other formats (ARMAX, CB1-6, CB7+, AR2, GS, etc.). However, you can use
tools such as OmniConvert to convert any of these formats to RAW.

Settings File
Settings are stored in an ini file named “CheatDevicePS2.ini”, which needs to be located in the directory Cheat Device is run from. The cheat database path and additional boot paths are set here. See the included settings file for an example.

Included is the CodeBreaker 10.0 database. Please report any bugs to me if you find them.
