did the meowth version ever release?
They did release a Meowth version, but it's not finished.
Also....
Not sure if it's mentioned, but in 3.9 patch don't talk to the girl in the underground tunnel who trades for Farfetch'D. It freezes and kills the game.
Another bug I found is sometimes fire attacks leave a mon frozen instead of burned.
The saddle is cool, but maybe adding some dialogue like we are out of bicycles, but here's a saddle to ride your Pokemon!
Also didn't realize Carvannah and Sharpedo were given different looks, so kantonian forms!
Girafraigs tail looks kinda of like it's head and Sir Fetchd could have used more art work.
And some signs give off the message of trees.
Other than that I applied the patch to a rom copy of my Pokemon Yellow cart and it's really fun!
