My experience on getting Action Replay cheats to works on EZ-Flash Omega DE
Before sharing, I assume most of you are familiar with EZ-Flash CHT files, which can mainly be found through a quick Google search.
I began my custom CHT research when I discovered that the cheats for ROM 999 (Castlevania: Aria of Sorrow (USA)) were not working.
After extensive Googling, trying out various AR to CHT converters, and using ChatGPT, I found the following steps worked for me:
What you need: I will not post direct link or URL, not sure it's allowed.
Example 1
Example 2
Your final 0999.cht will look like this
Now you can test the cheat and add your own codes. I’ve had the most success with codes that write to RAM. However, this doesn’t mean all cheat codes will work—it just happened to work on a few that I wanted.
I hope this post gives you a better idea of how the cheat writes a value into an address for the EZ-Flash Omega cheat format. Share your tips as well, I believe there are more tricky codes out there to make certain game works.

I have tried Gamebreaker code as well, just make sure it is properly converted in the Code Converter, by selecting proper Devices, Encrypted/Not Encrypted etc... As long as you know the address, the value, number of lines.. You should be able to convert it to ez-flash cht easily. Cheers~

What you need: I will not post direct link or URL, not sure it's allowed.
- OfflineListGBA: Use this to get your ROM ID and determine which file to replace in the CHT folder. For example, Castlevania: Aria of Sorrow (USA), with ID 999, should be saved as 0999.cht.
- Or google "gba-by-number", the first 1 on the list should lead you to a website, then CTRL+F to search for your game, make sure the regions is correct with your rom. (J) / (USA) / etc.
- GameHacking.org: Search for "Castlevania Aria of Sorrow Action Replay GameHacking" in your search engine.
- Filter the cheat codes by "Action Replay Max" and select "Check Encrypted."
-
- Open a new tab and search for "code converter gamehacking gba", select "Action Replay Max" and check encrypted
- Understanding Cht format.
- [Cheat name]
ON={Address},{Value 1},{Value 2}
- [Cheat name]
- Cht format for multiple line, address, or value
- [Cheat name]
ON={Address1},{Value1},{Value2};{Address2},{Value1},{Value2}
- [Cheat name]
- Each line of address and value are splitted with semi-colon ";"
Example 1
- Ram Write, take this Max LUK for example
- Description: Writes 0x7F00 to 0x2013288.
- Address = 0x2013288
- Value = 0x7F00
- Converting into ez-flash cht file..
- ez-flash address = 13288. <-- getting this by removing 0x2, and any zeroes in the front afterwards i.e (0x2013288 = 13288), (0x2001234 = 1234)
- ez-flash value = 00,7F <-- getting this by removing 0x and reading every 2 characters from behinds i.e (0x7F00 = 00,7F), (0x7F270F = 0F,27,7F)
- write this into 0999.cht file
- [Max Lck ]
ON=13288,00,7F
Example 2
- Slide Code, take this All Accessories for example
- Repeats a write of 1 to 0x2013308 times, offsetting the address by and incrementing the value by.
- In this case, the cheat will repeat and write into ram certain number of times. We can decode this by using the code converter opened earlier.
- Copy the AR code and paste into the code converter
- make sure to select Action Replay Max, and check Encrypted, then Click Process Code
- notice the value in the breakdown
- similar to ram write, we have a new part called count: 20 (meaning it will write 20 times into the ram)
- what does that mean is that starting with:
- AR address: 0x2013308
- AR value: 0x1
- ez-flash address =13308 <-- removing 0x2, and any zeros in front
- ez-flash value = 1 <-- removing 0x and read every 2 characters from back order. In this case 0x1 = 1, if 0x01, i will still write 01, the value does not ignore zeroes in front like address.
- your cheat in 0999.cht will starts as follow
- [All Accessories ]
ON=13308,1 - it doesn't end here, we have the first address, and we need another 19 address, you can get by asking chatgpt to generate
- improvise to ask it to remove the 0x2 prefix etc, or write the code for you. the final All Accessories cht code will be as follow
- [All Accessories]
ON=13308,1;13309,1;1330A,1;1330B,1;1330C,1;1330D,1;1330E,1;1330F,1;13310,1;13311,1;13312,1;13313,1;13314,1;13315,1;13316,1;13317,1;13318,1;13319,1;1331A,1;1331B,1
Your final 0999.cht will look like this
