Robotron 2084 Blue Label cheats / game mods

Post by scott_tunstall »

I've produced some more cheats for Robotron (Blue Label), derived from my reverse engineering work at www.seanriddle.com/robomame.asm

*** FOUND PROTECTION RESET, NOW DISABLED ***

The cheats allow you to customise the game somewhat. You must enable the "Disable protection" cheat before enabling any other of my cheats.


I've played up to level 34 with these cheats with no ill effect. I had to disable robotron's protection for some of the cheats, so if you find your Robotron resets, please drop me a line (scott.tunstall@ntlworld.com) with the wave # and approximately how long the wave was playing for, so I can find the protection code responsible and disable it.


Here's the cheats:

Code: Select all

Re: Robotron 2084 Blue Label cheats / game mods

Post by scott_tunstall »

Hi,

I've created a new cheat that, I think, changes the gameplay to be more like Smash TV. Spheroids will now drop 5 GRUNTs at a time (until 15 or mor e GRUNTs are on screen), and loiter until destroyed.

You need to use my "disable protection" cheat before you enable this one . BTW my disable protection cheat disables all of Robotron's protection and will allow anyone to create game code modifying cheats. It does not patch the ROM checksum code, however.

The ROM space for the Easter Egg code that displays Larry and Eugene's names has been repurposed for this cheat, so the easter egg will no longer work.

Finally, this cheat is subject to change as feedback indicates it makes the game too hard - I'll probably slow down the GRUNT movement to compensate - but you can have fun with it seeing how long you last. Any feedback or suggestions welcome.


Code: Select all

  <cheat desc="Spheroids drop 5 GRUNTs (EXPERIMENTAL)">
  <script state="run">
      <action>maincpu.md@11205=12121212</action>  <!-- Overwrite spheroid drop code -->

I try to fix and convert codes to work in 0.265 or later version.
  • Disable protection
I disagree about filling routine with NOP. It's useless and painful for me.

robotron.xml, robotronyo.xml, robotronun.xml, robotron87.xml, robotron12.xml and robotrontd.xml

  • Simplified codes.
  • Sorted in address order.
  • Used temp variables to restore original values.
  • Moved explanation in "desc" to "comment" to avoid long title name in the cheat menu.
I doubt that he overwrites the routine between $D71C and $D72D.
Because stored value in $D72A is checked at $615C and $DE33 but these addresses are already skipped (See 3rd and 4th code).
So I removes that hack from original code though seems to be no problem.

BTW, the above code reproduces from my WIP code.
This code is very important because in-game ROM error causes serious problems (reset, freeze, crash and so on).

  • Merged codes with qword.
  • Used temp variables to restore original values.
  • Converted small letter to capital letter.
  • Removed duplicate codes for $3617
BTW, I don't understand the following in original code.

Code: Select all

      <action>maincpu.mw@12C1 = 07FF</action>
      <action>maincpu.mw@12C4 = 033A</action>
$12C1-$12C5 is routine, not data.
Before.

Code: Select all

12C1: E3 88 10       ADDD   $10,X
12C4: ED 88 10       STD    $10,X
After

Code: Select all

12C1: 07 FF          ASR    $FF
12C3: 10 03 3A       COM    $3A
What is his purpose?
I don't convert the above codes thought no problem.

  • Merged three codes into one.
  • Used temp variables to restore original values.
NOTE : Set before Wave starts to change the character.
