A gameshark code that works on VBA-M (SVN r878) doesn't work on mGBA

[LOuroboros]

Title.
I need to use a gameshark code to generate shiny Pokémon in a ROM Hack of Pokémon Emerald to check out something, and while the code works normally on my preferred version of VBA-M, it doesn't work on mGBA.
It's worth to note that this is also happening with a clean ROM of Pokémon Emerald, the same ROM that can be generated by building Pokeemerald.

I thought it was worth bringing up in case it's something that can or should be fixed on mGBA's end.
Perhaps I'm just adding the code incorrectly? I wouldn't rule it out since I can be tremendously dumb at times.

The gameshark code being used: F3A9A86D 4E2629B4 18452A7D DDE55BCC
And just in case it's relevant, the ROM Hack is called "Pokémon Shadow Specter".
EDIT: Oh yes, and after introducing the code I reset the game by going to File -> Recent too, not sure if it was needed or not.

You need to split it into two lines. The fact that it even lets you put it in as one long line is...a bug.

Since it's 2 lines of 16 characters each without counting blank spaces, couldn't mGBA handle it automatically?

Less troubles for the user 👀

Thanks for the clarification though.

Yes, that's why I called it a bug and not user error.

What year was released VBA-M r878? I think VBA-M 2.0.0 Beta 2 was released in 2015.

Please keep it on topic.

My point was: why keep such an old version of the emulator? Would not it make more sense to compare it with the current state of other emulators (or recent versions of this one)? Maybe that cheat is conflicting with something that was solved a decade ago.
