The thread wasn't approved because it didn't meet the requirements. From what I saw, you showed a few map edits, and the costume house... Well, I could be wrong, but it is very reminiscent of that in Pokemon Prism. I'm not necessarily saying you used Prism as a base (but if that were the case you should know that's considered theft, and as such is against the rules), but anyway, it just seems odd to me that a relatively new hacker would know how to implement something like that, and not have anything else to show.
At any rate, you'll need to show more progress, and make sure to re-read the Requirements thread before resubmitting. Apologies for not being able to get back to you, but Emulation has been extremely busy lately.
