Hacking Homebrew Convert a Cia File back to GBA, or add RTC to a Cia

[ObrigadaJim]

Some years ago i made a basic RomHack of pokemon FireRed called "Pokémon Steel" and nowadays i was interested in replaying it, the problem is i only have it saved in .cia format, cause at the time i converted the .gba file to .cia using the New Super Ultimate Injector so i could play it someday on my 3ds.
The thing is, by acident i probably didn't put it in the (+RTC) option when converting it to a cia and now the game doesn't have the internal clock working and its always night making the game all darker and making it impossible to get any of the day exclusive pokémon encounters.
I tryed to search a way to extract or convert the .cia file back to a .gba format so i could then re-convert it back to a cia fixing the (+RTC) hissue this time, but didnt found anything related to converting cia to gba.
So does anyone knows how to do this convertion?.. Or does someone knows how to fix the (+RTC) hissue without needing to convert it?

thanks for the atention and sorry for any grammar error, englihs is my 3rd language.

You probably won't find anything exactly like that, but have you tried looking for a generic .cia unpacker? A quick Google turns up https://gbatemp.net/threads/tutorial-how-to-decrypt-extract-rebuild-3ds-cia-cxi-files.383055/ .

I'd recommend giving it a google

Good luck!

Did you get anywhere with this?
I am attempting to convert a .cia of Pokemon Crystal to .gbc for use on a homebrewed wii via vbagx emulator.
