Hey I didn't mean to annoy you or anything. I just thought I should ask you since I asked a lot of other people. Thanks for the help. And fireworks if you are reading this I did post my question on the simple question post!
Sorry, but I can't answer that as I don't hack Emerald :<
ASM is the highest and generally hardest form of hacking available to us. It involves going into the ROM and changing complex routines. Here is a thread that you can read, but it is pretty hard to get into unless you've done something similar like in a computing class beforehand. As I said previously, it would be easiest to just ignore this feature for now and come back to it later once you've digested everything and built up your knowledge.
Also, I agree with Fireworks' VM. Mods are here to keep order in the forums, not to be a dispensary of tutorials and tips for hacks. We don't know everything so general hack questions should be put into the help threads which are provided :)
Unfortunately no, the ability to have a double battle with somebody on your team wouldn't have been put into the games until Pokemon Emerald (like your example of the Space Institute as well as at the Battle Tower) so I'm afraid that FR wouldn't have the ability to that without ASM hacking. You wouldn't be able to simply port over the routine that allows you to do this in Emerald without editing it to fit FR standards. This means you're going to have to leave that feature of your hack out unless you can contact an ASM'er to help you/ you learn how to do it yourself. Please don't ask me to do it since I can barely do anything with ASM :P
tbh, if I were you I would just move on and keep working on other areas of my hack.
Hey DrFuji I actually do have a question for you. How do you create a double battle in pokemon firered that is that is like the one that you have against team magma in pokemon emerald. I have asked other moderators and everyone doesnt seem to know. I also asked my question on the simple questions post and no one answered. So, if you have the time, please answer back. Thanks in advance.
