I don't know if anyone has tried kleenexfeu's
Mega Evolution in Emerald, but I found some problems.
Apparently, the only one that works perfectly is the Wish Mega Evolution. However, the other two, Primal Reversion and Mega Evolution with an item...not so much...
Primal Reversion...flat out doesn't work. I used G3T AND G3HS and it still won't work. All I get is this:
Been a while since I didn't test this version, but I never had this bug.
Then, with Mega Evolution with a Mega Stone, it works...to a certain extent. I gave my Venusaur a Venusaurite, and when I activated it, the game locked up...for 30 seconds, THEN it activated.
Same.
Once it Mega Evolves, however:
Same.
That's not Mega Venusaur, I made sure a few hundred times. Has anyone else have this problem?
Also, there was one other glitch that I found where the Pokemon would stay as the Mega. I fixed it very easily. Just set the Mega Evolution option or Primal Reversion option to the Mega form to the original Pokemon. BUT, set the argument to 0 in G3T, or in G3HS, if you have an item, set it to the very first item, or the ??????? one. If you have a move, set it to the - option, which is the first option.
It is in the explanations if I remember well
