06 OCTOBER 2023

Another maintenance release, added various cheats posted on the forums (mainly from Abystus) and some cheats I've made.

Here is the cheat collection update for the latest MAME (0.259).

XML/JSON Cheat Collection for MAME 0.259 [3856K]


Note: The XML/JSON Cheat Collection archives are double packed. Inside the downloaded zip archive you will find a large cheat.7z. It's this cheat.7z that should be placed in the same directory as your MAME execute-able.

Read the cheat.txt file contained in the cheat0257.zip for more information. If you spot any errors (non-working cheats or parsing errors) then please post them in this forum topic .

Similar maintenance release to this time, although I've also made cheats for most of the Exelvision EXL 100 software list games and I've started to make cheats for the Amstrad GX4000 software list games.

Here is the cheat collection update for the latest MAME (0.257).

Ok, it's been over a year since the last release, this time around it's simply a massive update. I've been adding cheats fairly silently for the various MAME software lists for a while now, this time I've converted SMS, NES & SNES cheats into XML format. The cheats will need testing, tidying & renaming but that a job for another day (or another lifetime). The raw NES/SNES cheats for conversion were donated by GameHacking.org, a great site and resource - thanks guys (especially rimsky82).

So here is the cheat collection update for the latest MAME (0.221).

08 FEBRUARY 2019

The cheat collection is 21 today! I simply can't believe 21 years have gone by so fast! If I'd realised that MAME was going to emulate so much I probably would never have started...
Anyway without further ado here is the cheat collection update for the latest MAME (0.206).

12 AUGUST 2018

Here is the cheat collection update for the latest MAME (0.200). I simply couldn't leave a double zero MAME release pass by without an updated cheat database.

07 JULY 2018

Here is the cheat collection update for the latest MAME (0.199). It's been a whole year since the last release, sorry about that!
Hopefully, the next release should be sooner as I still have quite a few things to clean up and add now that I've done most of the grunt work.

07 JULY 2017

Here is the cheat collection update for the latest MAME (0.187).

See the MAME Cheat Files section for a link for this version which has now been superceded.

Since MAME 0.186 crazyc has made some more really useful changes to the LUA cheat plugin (accessed via the Plugin Options\Cheat on the MAME TAB menu):

1. You can now once again assign cheats to activation keys and it's actually a lot easier than it used to be, you can do it via the "Set Hotkeys" option in the menu or directly by editing the gamename_hotkeys.json file in the cheat directory.

2. The ability to add Game Genie codes direct to the cheat.simple file in the cheat directory, eg:

nes/3dworldr,gg,AEUOLTPA,Infinite Lives
gameboy/addfamu,gg,C9E-F8E-081,Infinite Energy
gamegear/alien3,gg,002-B1C-3B7,Infinite Energy
megadriv/aaahhrmu,gg,ACFA-AACC,Infinite Lives
snes/aaahhrmu,gg,C282-04A7,Infinite Energy

Of course you can already use the cheatfind plugin option to find cheats if you can't get along with the debugger commandline cheat searching commands or want to try some different methods.

If you can't see either the cheat/cheatfind or plugin options via the tab menu, add the following text to the plugin.ini file:-
cheat 1
cheatfind 1

To read more about the plugin cheat engine or ask questions then have a look at this forum topic.

30 MAY 2017

Jumping the gun for this release, here is the cheat collection update for the latest MAME 0.186 (due release tomorrow). The highlight of this release is that it now contains cheats for 1929 games from the PSX softwarelist, I've collated the cheats from various GS/AR lists and converted them into XML format for ease of use.

27 JUNE 2015

Cheat Collection Update for the latest MAME. Note, with this release the MAME cheat file no longer just contains cheats for arcade games it also contains cheats for the softwarelist based home computer/console systems formerly solely part of MESS. There is at least a 'placeholder' cheat file for every individual softwarelist entry, though there are actual varying numbers of cheats for games in the advision, arcadia, coleco, gamegear, gamepock, jaguar, lynx, megadriv, megatech, neogeo, nes, nes_ade, pce, pv1000, pv2000, samcoupe_flop, sgx, stv, sv8000, tg16 & vii software lists. There are long-standing issues with slot ROM cheats in the former solely MESS systems so only RAM cheats will currently work in those systems - so if any cheat does not operate as described it is likely for that reason; so please do not send/post bug reports for ANY softwarelist game.

10 SEPTEMBER 2009

Some big changes in the MAME cheat world, thanks to Sandro Ronco we now MAME RAM cheat searching functionality again, which you will find in the debugger. So let the games begin. This cheat collection is for use with 0.134 or later. See the downloads page for a link for this version which has now been superceded.

11 JUNE 2009

There's still not that much in the way of new cheats for many of the new games as there is still no built-in MAME RAM cheat finding functionality. This cheat collection is for use with 0.132 or later. See the MAME Cheat Files section for a link for this version which has now been superceded.

28 APRIL 2009

This release brings the XML cheat collection up-to-date with the various name changes and new clones added since 0.126. There's not much in the way of new cheats for many of the new games as there is still no built-in MAME RAM cheat finding functionality. This cheat collection is for use with 0.131 or later. See the MAME Cheat Files section for a link for this version which has now been superceded.

31 MARCH 2009

Decided it was time to give the site a little spring clean as it's 10 years to the day since the last redesign. Lean, clean and quick are the orders of the day - not sure if I like it though.

As many of you are aware the old cheat engine was hacked to death during the 0.125 update cycle, it was so bad that the whole cheat engine was ripped out during the 0.126 update cycle. A completely new and more resilient cheat engine was written by Aaron Giles during the 0.127 update cycle. This new cheat engine works in a completely different way than the old cheat engine, though the casual cheater should notice few differences as the differences are behind the scenes. The cheat.dat is now officially dead, replaced by 7000+ xml cheat files (though they can be kept in a single zip). The cheat format as expected is unrecognisable from before, but it is a lot more powerful. Unfortunately, so far there is no cheat finding functionality in the new cheat engine...hopefully this will get addressed soon.

Right there are two releases today. First of all, to close off cheat.dat once and for all I include the LAST EVER cheat.dat file. This cheat file is meant for use with a MAME 0.126 that's been compiled with a working cheat engine rather than the one contained with the 0.125 updates. I've included a link to the last known good cheat.c for MAME 0.126 so if you are capable of compiling your own - drop that into the right place and type make. Before anybody asks, no it's NOT possible to compile the old cheat.c into newer MAMEs as since 0.126u1 there have been a series of changes to the memory/cpu system that makes it all but impossible.

Classic cheat.dat cheat file for MAME 0.126 [ZIP FORMAT - 1407K]

Classic cheat.dat cheat file for MAME 0.126 [7z FORMAT - 824K]

Working cheat.c for MAME 0.125u7 - 0.126 (need to compile)

Secondly, I've converted the above 0.126 cheat.dat file into the 7000+ xml files of the new format. This cheat collection is for use with 0.130u2 or later. See the MAME Cheat Files section for a link for this version which has now been superceded.
