Hey, I found some things I noticed, but I wasn't sure if I should PM you instead.
*You get a free Hoenn Starter instead of one of the monkey trio.
*Less than three Pokemon in triple battle locks up.
*For when you battle Chili, Cilan and Cress, the mugshot shows the order they're standing, but when in-battle, Chili and Cress are switched as well as their respective Pokemon.
*I noticed the different trainer classes.
*I also noticed that Brock "replaced" Lenora which was kinda hinted when you got TM Retaliate from the girl when you usually get it from Lenora. (Sorry, if this spoils anything.)
*Before you battle Brock he says, "I am the temporary director of [...] Lenora is currently doing some fossil (cuts off)" I think it was supposed to say "...fossil research" or some other.
If there were any graphical glitches I didn't see any because the top screen on my DS Lite is not working right. As in, the screen has a red tint, and can't see the colours correctly.
Although it would be nice to have a location guide, but sometimes I think it's better without it. More of a challenge having to find all the Pokemon yourself.
I'm having a lot of fun trying to find all the Pokemon in each route/cave/city/town. I'm about to go through Pinwheel Forest and catch Team Plasma.
