Hi there Harry :D, welcome, welcome,welcome to the friendly and fun community of PC! So are you enjoying yourself so far :3? I use to play GBA and PC games for fun a while ago and I did use to have this urge to create my own game, unfortunately my talents didn't lie on that aspect so it faded away eventually. I'd still be keen to see it though, give me a shout when you publish it alright :3?
We have Game Development and Emulation, they're sections filled with tips,guides and tools. I'm sure it'll be a big help for you, so see if anything might be of use to you alright :D? Anything else you want to do while you're here?
There are endless things to do here, besides hacking, you can welcome new users and make them feel comfortable at PC, maybe have your say in Pokemon and non-related polls, do some fun forum games,join some fanclubs, discuss about the Pokemon series, tabletop games, art, writing, the list goes on, if I stretched it out it would probably go from Earth to the next galaxy :D. That's how much you can do at PC, it's impossible to get bored n_n.
I'm Rainbow by the way, I'd be happy to talk with you (although hacking is off-topic for me unfortunately D:) and hopefully I'll see you around the forum alright :3? Have fun at PC Harry!
