    • Hello, I have been editing a hackrom, and I wanted to test the link battles and link trades, but I have noticed that it is somewhat unstable, the connection is established but, sometimes at a random moment the connection drops out of nowhere. If I remember correctly the special 0x20 and 0x21 correspond to the Battles and Trades function, but I don't know what offsets the rom is in and I would like to know where it is to check if changes were made without realizing it. I know the Special Table starts at 15FD60, but I don't know where it ends.

    Does anyone know the offset of the special 0x20 and 0x21? Or where does the Special table end?

    Additionally, I am also interested in knowing what function the other specials fulfill in Fire Red. Thanks in advance.

    Each special is a 4 byte function pointer. Thus the pointer for special 0x20 starts 4*0x20 = 0x80 bytes after the start of the table.

    You can find a list of specials with descriptive names here.
    For example if we want to find the name for special 0x20: The special definitions start at line 11 in the file, 0x20 in decimal is 32, the definition for special 0x20 is on line 11+32=43:
    Code: 
    def_special EnterColosseumPlayerSpot

    You can then search for the function name to find the code for it if you want to see what it does.
