Incorrect codes?

[ReyVGM]

I was trying the codes found here for Daffy Duck Marvin Missions (GB) and only one of them worked:

Infinite Jet Pack 01009EFF
Invincibility 0101C6C0 (Worked)
Infinite Lives 010298FF
Infinite Energy 010599FF

It's strange too, because official gamegenie codes didn't work either (on an emulator of course).
I tried the USA, Japanese and original non Super Game Boy releases.

which Emulator are you using ?
rehacking the codes they are correct

I'm using VBA.

You say they are correct then?

[Hybrid]

yeah they are correct

Hmm strange, I tried them on BGB and they worked fine, but not on VBA (version 1.8).
On VBA it said "invalid gameshark code".
