IS there any example/guide for disabling collision detection?

[Helder]

Try using this MESS, click on the MessUI.exe as that is the windows interface version. You will have to configure the controls and Roms folder though, download the 2 parts and then extract using winrar or 7zip.

How can I manipulate cheat option in mess?
Is there anyone who make use of cheat function in mess emulator?

The cheat engine as described in that guide has been stripped out. Instead, you can use the debugger to find and make cheat codes in mess. Pugsy has some nice tutorials at his site on using the debugger (mame and mess are the same). It's a different beast, and has a bit of learning involved, but it's very powerful.

The cheat option still exists, but only enables the use of cheats that exist already. So, even if the cheat menu is enabled, it only shows up if it has found cheats for that game.

Thanks alot for all of your answer.
I now use Messui, Its interface is GUI and it even supports to mount or unmount any rom files for executing it really very easy to control.
Mess' debugger integrate with cheat engine I refered to below mame cheat tutorial and type "help cheats" in debugger command line for more expertise and It seems to have Powerful functions as rimsky82 pointed out.

I found a address for flashing invincibilty,and log this code to txt files(cheatlist found.txt) but How can I create a new cheat file in order to enable cheat option?(I would like to create cheat code of games which doesn't exist in anywhere )
I just mounted chd files from device view tab,And this chd file is not the exactly the same name with disk name from pcecd.xml file in hash folder.
how should I name/create cheat files in this case in order to cheat option take effect?
and Is it possible to change value of address I just have found or to replace it with NOP or other opcode command in mess' debugger?

cheat file always use default R** name

codes have to be in XML format like other XML cheat files.

what game you hacking, this help us, help you better.

The name I have tried to hack is tg16/pcecd game of "Faussete amour" and it was stored in pcecd directory(path:\roms\pcecd) named as "faussete amour (scd)(jpn).chd"
I created a new faussete amour (scd)(jpn).xml file with windows xp build-in notepad as there is no Mess cheat code for "faussete amour" in public.
I paste below context into faussete amour (scd)(jpn).xml then save it to the root directory of Mess.
But there is no cheat option in config menu.

<mamecheat version="1">

<cheat desc="Possibility 1 : 102CA9 (00)">
<script state="run">
<action>:maincpu.ppb@102CA9=16</action>
</script>
</cheat>


</mamecheat>

and Is there really no way to change address of value?
If it is impossible,Should I edit .xml of cheat file,then enable cheat option in order to change desire value of address?

I did a few of these for N64. I dunno how those guys at Galoob did it for so many older games all those years ago. My method was to trace it from health using a breakpoint on the health address being written while taking damage. Tracing it back and killing the jumps/branches until I got back far enough that the player was completely unaffected by attacks.

Galoob had a lot of time on their hands.

You need to check mark cheats on Mess GUI under the game's options miscs.

faussete amour (scd)(jpn).xml in cheat folder on the root level of mess

or inside cheat.zip fie on the root level of mess, extract and edit the pce.xml and add this


<cheat desc="-= faussete amour (scd)(jpn) =-"/>

<cheat desc="Possibility 1 : 102CA9 (00)">
<script state="run">
<action>main.rb@102CA9=16</action>
</script>
</cheat>

I have downloaded cheat.zip labeled as "MESS TG16 V1.01 Cheat File FOR MESS 0.129" from below url then followed your instruction,(make "faussete amour (scd)(jpn).xml" with notepad add your contents,embed it to cheat.zip) but It also fail to enable cheat options.

I also tried to tg16 games of "Jackie Chan's Action Kung Fu" as well as "faussete amour" but whenever I run it give me error message that say
tg16.xml(7): error parsing cheat expression "main.rb@1F0820:03" (invalid memory name)

Now,I am using mednafen gui and I found out the reason Why I have failed to set bp on mednafen.
In order to use address of cheat results for Breakpoint ,I have to put *(asterisk) in front because address result of MF cheat-engine' form is physical address.
eventhough MF doesn't support a command for tracing cpu to files but it has basic options for debuggering and It would be sufficient for novice cheater like me.
