I have just checked the hex list and realized that with the added hex of 39 only the pokemon with hex of 211, 213, 214, 220-223, and 230 onward will be available via Johto Cloaking Glitch. That's 25 that are not available. However some of those 25 are already available via evolution and even more with the 32 that will be available. It is also possible that we may find a way around the whole add 39 to the hex thing.
I think I will go ahead and use my gameshark to speed through the game. I'll try to have the results either today or tomorrow.
I know i double posted. Ever heard of a breakthrough? That takes 3 years...
Edit: No wait you should be able to get all the glitches. If you were to trade a chikorita why would it not add 39 to the hex.
