[totlvice, evilngt] Konami M2, Screen Flashing

[pr140n]

I'm going to request another f̶i̶x̶/cheat, this time for the games Total Vice (totlvice) and Evil Night (evilngt) to stop the screen flashing when shooting.

Best regards,

Only looked at totlvice so far, and CPU wasn't fun to trace. Ran this with -nodrc option so may need to enable it before the game starts - and only quickly tested.

Code: Select all

  <cheat desc="Stop Screen Flashing on Shooting">
    <script state="run">
      <action>ppc1.pd@40080CFC=B14C0000</action>
    </script>
    <script state="off">
      <action>ppc1.pd@40080CFC=4BFDB619</action>
    </script>	
  </cheat>

Might look at evilngt if totlvice cheat works ok

With normal weapons, everything works fine, but it still flashes with the double magnum and limited ammo weapons.
It seems like MAME replaces the flash with the previous frame—this game is going to be a problem.

It didn’t work on evilngt

It was never going to work on evilngt (never said it would)....it's a different game

Game is painful to play as I have to play it with the debugger activated with trace.

This should hopefully fix the issue with the extra frame and possibly the double weapon (not tested enough - poke value may need tweeking as I seemed to lose the guns too quickly)

And it's still only for totlvice...but still a wip as not much time at the mo

Code: Select all

    <script state="run">
      <action>ppc1.pd@40080CFC=48000048, ppc1.pd@40081238=4800006C</action>
    </script>
    <script state="off">

    </script>	
  </cheat>

I misinterpreted about evilngt

frames and the double magnum, ok
but now with the double magnum, when I press the trigger once, it unloads the entire weapon
