I see, that sounds tough. You will need to get a lot better at ASM. I can tell you that JPAN found the table (i believe it is in his notes that came with the hacked engine v1.0) of all special routines. So, you wouldn't need ASM to find it, but to edit it, deffinately.
I only know basic ASM (surprisingly not going to be enough), and I was trying to put in an underground in Gen 3. Capture the flag, synced characters, and mining. I'm not going to stop trying till i get it tho.
For this particular thing, I want to edit the Union Room to transmit the current location of the character.
