Is it possible to update the action replay with a custom firmware ROM?

[arhacker]

I opened the ram of the "Action Replay Code Manager" program and found the links that the program uses to retrieve the NDS ROM to update the action replay. So has anyone ever edited the links to make the program update with a different ROM than the ones it uses for firmware updates?

I found that the program goes to "http://us.codejunkies.com/nds_actionreplay/update_info_us.asp" and chooses a link from which to download the NDS ROM.

I have also noticed that the ROMs are .bin files and that the first 8 bytes must be removed before the ROM will work in an emulator.

If we can get it to update with our own ROM, then we could turn our Action Replays into flash carts.

I'm pretty sure that's not how it works. On the other hand, maybe you could add some functionality that is currently missing, such as HGSS save support on the AR DSi?
