(SOLVED) MAME "standalone" Cheats for systems like Coleco, Arcade and more

[DTEAM]

@folly
No sorry, for Arcade and jaguar, I did nothing excepted what you see above with mame.ini and cheat.7z file location.

for -cheat in emulators.cfg , I did a test with jaguar and nothing happens. mame.ini seems to do the same thing.

For some reason, we can load cheats for arcade games (MAME) and not for systems from the old MESS

Ok I understand it correctly.

What is your emulators.cfg of Arcade then ?

@folly
those 2

mame_autoframeskip = "/opt/retropie/emulators/mame/mame -c -autoframeskip %BASENAME%"
mame = "/opt/retropie/emulators/mame/mame %BASENAME%"

Yes, just what I was thinking/explaining in my earlier post.
Your edit1 doesn't run through the softwarelist and your edit2 does.
In both (Arcade and jaguar) you use MAME naming, as you said,
but with jaguar you added the system in the commandline so the MAME naming for the softwarelist is not used/rejected.
So the question is, do cheats only work when a game is loaded the softwarelist way.

Pfff... do you follow it ?

Can you try your jaguar game (with MAME naming) from the Arcade rom directory, to see what will happen ?
Perhaps you also have to add a hash table for jaguar too in you mame directory.
Here are hash tables :

@folly
Not working. In mame.ini , It already pointed in the hash folder with xml. The xml. are already there.

@folly
Not working.

Do you have hash tables ?
I think the have to be in :
/home/pi/RetroPie/BIOS/mame/hash

[DTEAM]

@folly

Yes, and in 2 places (lr-Mess and MAME) . For mame, It's in the mame.ini and Its full by default, unlike Lr-Mess

My hashpath
/opt/retropie/emulators/mame/hash;
/home/pi/RetroPie/BIOS/mame/hash;

[Folly]

@dteam
And you have the jaguar.xml in there ?

[DTEAM]

@dteam

What %BASENAME% doing
Can we use it in

mame-jaguar= "/opt/retropie/emulators/mame/mame -c -autoframeskip -cheat jaguar -cart %ROM%"

with jaguar

[Folly]

@dteam

I am quite certain basename is the romname without the extension.
So the basename is looked up in the hash tables then it knows the :

• game
• system
• etc.

[DTEAM]

@folly
yes, jaguar.xml is there
Before I use your script, I installed Lr-Mess systems manually with .xml files.
I'm running both. I'm familiar with It.

[Folly]

@dteam

Is your jaguar game with the correct checksum in the jaguar.xml hash table ?

[DTEAM]

@folly
No, games are in the rom folder and xml (for mame) in /opt/retropie/emulators/mame/hash and for lr-mess in /home/pi/RetroPie/BIOS/mame/hash.

/home/pi/RetroPie/roms/mame is a cut and paste mistake, sorry

Is your jaguar game with the correct checksum in the hash table ?

Yes, because I'm able to run It with this line and It required the .xml file:

lr-mess = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mess/mess_libretro.so --config /opt/retropie/configs/jaguar/retroarch.cfg %ROM%"

This line doesn't work if I delete the .xml file in the hash folder

[Folly]

@dteam

I think we have a missunderstanding.
Well, this happens with how MAME works , haha ;-)

I really meant, open your jaguar.xml in a texteditor and look for your game.

Edit : looking at your post it looks indeed you have a good rom with a good checksum, because it runs with lr-mess.

[Folly]

@dteam

Can you try to make a jaguar folder in the arcade rom directory ?
And run the game from the arcade/jaguar directory ?

@folly
see also: Mess cheats

*Activate Cheats
You can activate cheats in MESS by selecting them in GUI or by using the -cheat option at command line. Unfortunately, cheats are currently not working in MESS after MAME 0.127 cheat rewrite.

More precisely, you can add cheat in xml format as system.xml but you cannot currently add per game cheats as in previous versions. They should be re-added soon.*

But here, the seems to be able : http://www.mamecheat.co.uk/forums/viewforum.php?f=2

@dteam

Seems like we are running into a dead end for now.
Perhaps we have to look at this again later on, do you agree ?

[DTEAM]

@folly
yes, I agree

[DTEAM]

@Folly
Like this, It works:

mame-jag-cheat= "/opt/retropie/emulators/mame/mame -c jaguar %BASENAME%"
mame-jag-autoframeskip-cheat= "/opt/retropie/emulators/mame/mame -c -autoframeskip jaguar %BASENAME%"

Note: for jaguar, ssometime better performance without autoframeskip and sometime with It.

You must add MESS system name before %BASENAME%.

To use cheat codes with MAME/MESS, your roms must have the MAME roms names from the HASH file.

You must add in mame.ini :

cheatpath /home/pi/RetroPie/roms/mame/cheat
cheat 1

(note : I did a test without cheat 1 in mame.ini and without -cheat in emulators.cfg and It also worked)

You must put cheat.7z file from "Pugsy's Cheats " in /home/pi/RetroPie/roms/mame/cheat

You must have the system hash file like jaguar.xml (with MAME standalone, It's already there)

@dteam

That is just what I was thinking tonight.

Cool, we were on the right track ;-)

Well, still we have to learn allot about MAME, we are not finished yet with learning !
