Need help with Gen 1 Legendary bird resets

[HaloSlayer255]

Hello all,

Wondering if I can reset the Articuno and Zapdos sprite encounters in Pokemon Yellow, tried using PKHex and it appears unsuccessful. I found a gameshark code to respawn Snorlax but only got the one west of Celadon city to respawn.

I've read the posts in this thread:

and also one of its links with a gameshark code list, tried a few combinations for Articuno such as beginning the code with 91 and editing D2D5 to D3D5 and back no success, Zapdos no success on those codes either.

Has anyone been able to reset the .sav events? Attached is the attempt I made that needs verified in case I missed something, and a save without any flag reset attempts as a fallback.

Thanks in advance,
