However, I face a few issues, such as Map name changing (To a custom name), some issues with tileset editing but the main problem is events. I do not know how to add my own events and ARGH.
Is there an alternative to Johtomap people can link me to please? I searched but can't find anything... Cheers!
If you're going to make an overhaul of G/S, you're going to have to learn to deal with lots of "problems" you wouldn't run into when hacking 3rd gen games (such as space for writing data and such). I've made several video tutorials in youtube so you may want to check them out (others in skeetendo inc. have said they're good so I could as well favour them to you too).
