Erm i'm not sure if i'm supposed to post this or not here (i'm a noob so apologies mods!) but basically if anyone still has the Version 4 beta & happens to get stuck at the 4th gym.
Simply find the Pokemon Ruby gameshark cheats somewhere... won't say where lol google it or something if necessary. Use the walk through walls code, the Ruby cheats will work as it's a Ruby hack. But like i said cheating isn't encouraged lol, but in the case of Beta 4 of Ruby Destiny, if you have problems, then use the walk through walls ruby code & voila, you can face the 4th gym leader but you'll have to put up with the background.
Personally i don't mind the odd glitch or error. I think the hack's awesome & credit to Jagold (ithink) for making it.
