It's dangerous code.
Origianl program code.

Code: Select all

0148C2  tst.w   (A4)                                        4A54
0148C4  bpl     $148ce                                      6A00 0008
0148C8  moveq   #$11, D0                                    7011
0148CA  move.b  D0, ($b,A2)                                 1540 000B
0148CE  move.b  #$1, ($e,A2)                                157C 0001 000E
0148D4  tst.b   ($e,A3)                                     4A2B 000E
0148D8  beq     $148f0                                      6700 0016

mezdap replaces 0x6A00 with 0x6A0A at $148C4.
But...

Code: Select all

0148C2  tst.w   (A4)                                        4A54
0148C4  bpl     $148d0                                      6A0A
0148C6  dc.w    $0008; ILLEGAL                              0008
0148C8  moveq   #$11, D0                                    7011
0148CA  move.b  D0, ($b,A2)                                 1540 000B
0148CE  move.b  #$1, ($e,A2)                                157C 0001 000E
0148D4  tst.b   ($e,A3)                                     4A2B 000E
0148D8  beq     $148f0                                      6700 0016

• $148d0 is UNEXPECTED "ori.b #$e,D1" (0001 000e) in program code.
• If "bpl $148d0" at $148C4 is false, $148C6 is executed and the game throws illegal instruction.

Fixed code is the following.

Code: Select all

    <cheat desc="Reselect Character">
    <comment>Lets you reselect character on the select screen for P1 and P2.</comment>
        <script state="on">
            <action>temp0 = maincpu.rb@148D1</action>
        </script>
        <script state="run">
            <action>maincpu.rb@148D1 = 00</action>
        </script>
        <script state="off">
            <action>maincpu.rb@148D1 = temp0</action>
        </script>
    </cheat>

Thanks again, same reason, trying to add hidden characters (Mizuki and Kuroko) to select screen...And current 'select character' cheat for this game and the other ones are not working that I want! Tried to fix them but failed! So I start making these.
This is the address that I use first: maincpu.rw@0148C6=000A
