Emulator Cheats

When I play a game and go to activate the cheats, it keeps taking me to the auto-fire option only. I placed the cheat file in the main mame folder alongside the mameui. Tried it with a few different mame 0.174/0.175 versions but it keeps asking if I want to turn on auto-fire, but no cheat list even though I have the cheats option turned on in the menu.

Edit: Erm, nevermind I guess, now it works.

It seems that Golden Axe: The Revenge of the Death Adder has a memory parse error and has since January 2015.

Works absolutely fine here, are you sure you using the correct cheat collection version to go with the correct MAME version?

If you are using the 0.174 cheat collection you should ideally be using MAME 0.174

Looking at your history I've mentioned this already (though as you never replied I don't know if you ever read it):-

viewtopic.php?f=1&t=6187&p=16069#p16069

So I re-iterate please make sure you match MAME version to Cheat Collection version.

Thank you for your quick reply. It's funny that only Golden Axe Revenge is giving me an error. Every other game works fine. This is weird.

I noticed on both this version, and the last version, some of the cheats for [mk2] are incorrectly placed in [mk]. It starts from the "Restore Shang Tsung's Kombat Tomb" cheat to, possibly "Jade Clue Character Modifier".

Honestly I'd been trying to fix it myself but have had zero luck doing so.

Bump for the new 0.184 collection

Unfortunately I can't currently update cheat.retrogames.com so grab it from my signature or from the mamecheat website :-

Invincibility cheat for Inferno (Williams) is not working properly. When I disable the invincibility, it never turns off. This later causes the game to crash showing a ROM error and the game resets itself. If this can be fixed, it would be greatly appreciated.

Cant see the problem myself as I've not played it enough to see it bank the ROM out which I guess is what is causing the problem....

Maybe this will work better? :-

Code: Select all

  <cheat desc="Invincibility">
    <script state="on">
      <action>temp0 =maincpu.mb@153A0</action>
      <action>temp1 =maincpu.mb@16D01</action>
      <action>temp2 =maincpu.mb@16D7D</action>
    </script>
    <script state="run">
      <action>maincpu.mb@153A0=39</action> <!-- Boom-Boom Bird -->
      <action>maincpu.mb@16D01=20</action> <!-- Tanks -->
      <action>maincpu.mb@16D7D=20</action> <!-- Cyclops -->
    </script>
    <script state="off">
      <action>maincpu.mb@153A0=temp0 </action>
      <action>maincpu.mb@16D01=temp1 </action>
      <action>maincpu.mb@16D7D=temp2 </action>
    </script>
  </cheat>

I can confirm this works better.

Bump for new 0.187 collection

Posted: **Sat Jul 08, 2017 9:35 am**

Hi there. Newbie here.

I am using MameUI 64 0.187 and I don't see where to set the keys in the cheat menu option (when you pres TAB while the game is running) and the plugin options menu is empty.
You can only press the "set" option as always in the cheat menu, but there is no option to assign a key like in the controls menu.

What am I missing?
Do you have to use the plugin options menu; and if so? Why is it empty for me?

Any help would be greatly appreciated.

Also, I have detected the following error in Samurai Shodown 2:

Posted: **Sat Jul 08, 2017 2:22 pm**

I answered the other question already, but just in case someone comes across this post in the future...

Just looked at MAMEUI (I use standard MAME commandline here). I can spot the problem, if you run "mameui64.exe -cc" from the commandline it will create the plugin.ini file in the same directory but it only looks for it in the ini dir. You can create the ini file manually, just make a plugin.ini file in the ini folder (eg. C:\MAMEUI64\ini\plugin.ini ) and put this text in it:-

Code: Select all

#
# PLUGINS OPTIONS
#
cheat                     1
cheatfind                 1
console                   0
data                      1
dummy                     0
hiscore                   0
layout                    0
timer                     0

Thanks for the catch on samsho2, the cheats causing the problem were only recently added. My fault I didn't test them, but the person who posted the cheats is using an old version of MAME on which they work. Just need .m changing to .r in samsho2.xml (will fix on the next release).

The rest of the cheats work fine if you use the plugin cheat engine that you should now be able to see...the problem cheats will just have error next to them in the cheat plugin.

That did the trick.
Thank you very much!
I can't believe that after so many years using MAME, I can now set the hotkeys for the cheats... It's like a dream come true.
P.S. Sorry for the double post, I'm not a spammer or anything, I just wasn't sure where tu post.

Posted: **Sun Jul 09, 2017 6:31 pm**

yes i also noticed "samsho2" cheats not working,
that's right, i use older MAME (0.172) to find cheats because a lot things are broken in debugger,

@Pugsy

if you have contact with MAME developers-fixers, here is the issue i posted, seems forgotten or have less priority:
https://github.com/mamedev/mame/issues/2012
probably you're aware of these issues in latest versions while searching for new cheats, that's why i sticked to previous versions...

Posted: **Sun Jul 09, 2017 9:44 pm**

Just checked out the github report...didn't realise you had issues with the debugger, sorry.

Some of the pc!= stuff works as it's done for years, I use it fairly regularly and I've never noticed any issues.

The pc address should be the address it hits AFTER it's changed the memory, not the address that changes it so basically LOOK at the yellow cursor bar address rather than the PC address in the "stopped at watchpoint" message.

So from your github report it should be:-

Code: Select all

wp 9070D5,1,w,pc!=33062

rather than:

Code: Select all

wp 9070D5,1,w,pc!=3305c

wp 9070D5,1,w,{maincpu.pb@9070d5=01;g}
;invalid token error - it was working before

Must admit I never noticed that, I haven't used that for a while as I generally just test it with the cheat in XML format or just edit the address in the memory viewer.
I'll have a look at the source and see if I can fix the issue with ';' though, it should really work

Posted: **Mon Jul 10, 2017 11:24 am**

thanks for analysis,

yes, it seems they changed PC address handling with (memlocation of next instruction)
so your offer:

wp 9070D5,1,w,pc!=(next memlocation after trigger address)

works as previous versions, so i can again use latest MAME's for cheat finding.

that invalid token bug ";" is still there but yeah, rarely used.

ERRORS IN THIS CHEAT.

DEAR SIRS:

I WAS PLAYING GP RIDER. IN THE FOLLOWING VERSIONS.

IN (US) IN BOTH TWIN SETUP AND NORMAL WHEN YOU FINISH THE GAME THE GAME FREEZE OR SOMETHING AND THE GAME DOSENT ENDS. THIS HAPENS IN ALL THE VERSIONS.
I´M USING INVICIBLITY, INFINITE TIME, ALWAYS PLAYS 1ST.

IN (WORLD) AND J(APAN) IN TWIN SET UP THE GAME SAID IT HAS AN PASING ERRROR.
I USING MAMEUIFX VER 166 WITH CHEAT VER 187 AND PUTING THE CHEAT THE WAY IT SHOULD BE. THANKS FOR YOUR TIME.
CAN YOU PLEASE HELP ME.

FROM MARCELO JASSO S.

Posted: **Fri Apr 06, 2018 11:51 pm**

If you are using MAME 0.166 then you should really use "XML Cheat Collection for MAME 0.168 (Release Date: 7th December 2015)" as that's the closest release to the version of MAME you are using. That will probably fix the parsing errors.

As for the not being able to finish the game, it's possibly an oversight. I'd guess that the infinite time needs to be disabled at the end of the level....so either press F6 before you cross the line on the last lap or disable infinite time and wait a while for the game to do it's stuff (might have to wait 99 seconds).

Posted: **Fri Jun 22, 2018 3:19 pm**

Dear Sirs:

I was playing carnaval with infinite ammo and the game crashes. I think they need the followings cheats.
Finish this section now.
Yellow birds never appeard or drop.
when they eat the bullets too much the game crashes and they give you a game over.
Or when you kill all the things then you go to the next level.
Or when you hit all the pipes go to the next nevel.
Can you please help me.
