(tail2nos) slow CPU cars

Post by HazeWIP » Wed Apr 08, 2015 5:25 pm

game is hard as nails, this slows the CPU cars to a crawl.

was trying to find out where an extra graphic rom in a newly dumped set is used.

not entirely convinced the existing cheats work 100% either.

there's a nice structure in RAM here for each car during a grand prix, might be possible to make some more cheats out of the other values.

Code: Select all

<cheat desc="Slow CPU Cars">
    <script state="run">
     <action>:maincpu.ppb@ff8212=00</action>
     <action>:maincpu.ppb@ff8232=00</action>
     <action>:maincpu.ppb@ff8252=00</action>
     <action>:maincpu.ppb@ff8272=00</action>
     <action>:maincpu.ppb@ff8292=00</action>
     <action>:maincpu.ppb@ff82b2=00</action>
     <action>:maincpu.ppb@ff82d2=00</action>
     <action>:maincpu.ppb@ff82f2=00</action>
     <action>:maincpu.ppb@ff8312=00</action>
     <action>:maincpu.ppb@ff8332=00</action>
     <action>:maincpu.ppb@ff8352=00</action>
     <action>:maincpu.ppb@ff8372=00</action>
     <action>:maincpu.ppb@ff8392=00</action>
     <action>:maincpu.ppb@ff83b2=00</action>
     <action>:maincpu.ppb@ff83d2=00</action>
     <action>:maincpu.ppb@ff83f2=00</action>
     <action>:maincpu.ppb@ff8412=00</action>
     <action>:maincpu.ppb@ff8432=00</action>
     <action>:maincpu.ppb@ff8452=00</action>
     <action>:maincpu.ppb@ff8472=00</action>
     <action>:maincpu.ppb@ff8492=00</action>
     <action>:maincpu.ppb@ff84b2=00</action>
     <action>:maincpu.ppb@ff84d2=00</action>
     <action>:maincpu.ppb@ff84f2=00</action>
     <action>:maincpu.ppb@ff8512=00</action>
     <action>:maincpu.ppb@ff8532=00</action>
    </script>
  </cheat>

Thanks. I've modified the Time cheats a little to hopefully fix the issue with them not working, and converted the above RAM cheat into a ROM cheat which is probably overkill as the cars don't move and it now blocks the grid up :(

Code: Select all

  <cheat desc="Infinite Time">
    <script state="on">
      <action>temp0 =maincpu.mw@0066E2</action>
    </script>
    <script state="run">
      <action>maincpu.pb@FF8B15=00</action>
      <action>maincpu.pb@FF854B=28</action>
      <action>maincpu.mw@0066E2=4E75</action>
    </script>
    <script state="off">
      <action>maincpu.mw@0066E2=temp0 </action>
    </script>
  </cheat>

  <cheat desc="Stop Other Cars Moving">
    <script state="on">
      <action>temp0 =maincpu.mb@007E74</action>
    </script>
    <script state="run">
      <action>maincpu.mb@007E74=42</action>
    </script>
    <script state="off">
      <action>maincpu.mb@007E74=temp0 </action>
    </script>
  </cheat>
