Okay, ignore everyone elses way because hardly anyone here knows.
The solution to make you run indoors without bugs and stuff is in A-map's header view, change the map name type to 02. This will not show the map name on entering and will let you run in it. :3
Yes, thank you, it's working:D:D.
Although it was actually 05... Probably an Emerald thing. Thanks for your help, though, I wouldn't have thought of that otherwise. (It makes everything so much faster, lol). Thanks:D
