Why? The tiles are OK, and I doubt it is because of the ROM and the Base. (Did you Save the ROM in Advance Map? Just making sure, as it is easy to forget)
I'm sorry to say no again. Sorry, it is just the fact that... Well, I personally hate working on hacks, as then there is pressure to make it good, as I am expected to. In ROM Bases, no-one expects them to be made, and also, they can edit it if they don't like it.
Map (not done for ages), Tile Insert, Insert Pokemon (Sprites, stats, Moves. Too easy though). The basic things, really. So I'm not really a very good hacker.
That is funny. There is another one (not sure if it is on Youtube) where he puts a tape in the tape player in his car, and it turns out the mechanics who fixed his car sung a song about him on it... That wasn't very nice.
I didn't play the DK games either, if I am honest.
Nippy is just 1 scene of an episode, which is one of the 2 I have not seen yet. There are more, there's even a few episodes on Youtube, like the Eternal Quadrangle.
