[MRMIdAS]

So let me see if I'm understanding this.

<action>main.pb@0151=09</action>

<Action> </Action> is self explanatory, Main.pb I'm assuming means the main "board" of the game, @0151 is the memory address and =09 is the poke value?

[Pugsy]

main.pb@0151=09

main is the cpu tag, in the old cheat engine this would generally have been cpu0. Unfortunately the cpu flags can vary from game to game and there's a likelihood they will get changed ....just hoping that main will cover most things (I've handled the non-cpu0 cheats already as long as the tags don't change too much)

p is the type of memory it's writing - p is the standard RAM write, alternatives are m (ROM), e (eeprom) or r (raw write).

b is for byte and it's the size of the write - b byte, w word (2 bytes) d double word (4 bytes) and q quad word (8 bytes).

And yes you were right about the address and the poke

So that cheats pokes a byte of 09 into the address 0151 in the RAM area of the main CPU. It's contained in a script of "run" so it will run every frame.

Regarding byte/word/double/quad cheats, how will this affect cheats that use an odd amount, like 3 bytes (the old 00200000 cheats)? Would you need to split them into two linked cheats just for these to work? It sounds like a retrograde step to me.

I have only noticed this with the Tekken cheats I've been going through so far. The animations use 3 bytes for the ID, but the 4th byte shows which frame is being executed, not a double zero.

Example cheat:

Code: Select all

:tekken:00200001:265978:00114DD0:FFFFFFFF:Test PL2 Move
:tekken:00210001:265980:00114DD0:FFFFFFFF:Test PL2 Move (2/3)
:tekken:00210001:266690:00114DD0:FFFFFFFF:Test PL2 Move (3/3)

The above code is also harmless, I don't have a clue how to find the trigger which makes the move connect! The cheat simply runs the animation, whether it be a move, standing, blocking or falling, a win animation or anything else.

I suppose, making these reset the 4th byte to 00 would actually be better in a way, it would align everything instead of playing each frame randomly.

Here I go again, hijacking yet another thread with useless Tekken garbage!

Well, that was one of the big problems I had with the converter. It would have been easy if it wasn't for the fact that big endian and little endian were pretty evenly split (with LOTs of 3 byte cheats) so automating it was going to be a lot of work so what I did in the end was change all the Big Endian cheats manually and that ensured all the 3 byte cheats left where little endian.

Anyway the way to convert a 3 byte BE cheat into a 4 byte BE cheat is to change it from 3 byte to 4 byte, shift the poke value 2 places to the left and do the same with the mask so FFFFFFFF would become FFFFFF00

so as an example:

:batlbubl:00200000:F04C47:00060606:FFFFFFFF:Infinite Lives

becomes

:batlbubl:00300000:F04C47:06060600:FFFFFF00:Infinite Lives


and your example would become

Code: Select all

:tekken:00300001:265978:114DD000:FFFFFF00:Test PL2 Move
:tekken:00310001:265980:114DD000:FFFFFF00:Test PL2 Move (2/3)
:tekken:00310001:266690:114DD000:FFFFFF00:Test PL2 Move (3/3)

This works in the old cheat engine and is ok for conversion whilst untouched BE 3 byte cheats are not.

Thanks for clearing that up for me.

By the way, is it worth updating MAME and MESS to 0.127, or wait until everyone's 'happy' with the new cheat system? Hopefully not in two years time or something, but I'm not holding my breath!

Anyone up to making a standalone trainer which uses the 'good' cheat format? That would be awesome!

You could make it based on the MESS format by using the exe name and CRC at the start, for example:

Code: Select all

; [ ZiNc 1.1 - Tekken 2 Ver.A ]
:zinc:B1A7FCE2:00000100:66ECAC0:00000017:FFFFFFFF:Select Character's Moves P1
:zinc:B1A7FCE2:00000100:66EF450:00000017:FFFFFFFF:Select Character P1
:zinc:B1A7FCE2:00300000:66F43E8:00001734:FFFFFFFF:Infinite Time

The hard part would be making it appear when you hit Tab...especially when programs use everything from GDI to DirectX and OpenGL 3D modes etc.

hi, long time no see you guys, but i have SEVERAL work to do ...

first THANK YOU to puggsy for try make that convertor util...

and second, that yes, i dont like too much (well to be honest, i dont like nothing!) that new cheat system...

is very rare, and before that new system, in a single line of text you can write the cheat without none problems, or add all the cheats in a single cheat.dat file by simple edit that file and add your cheats at the end of the official cheat.dat.

i spend several years to learn all that (and after all, i dont know all about it) and this is starts all again from zero


and now, all those html lines really afraid me .
is true that i see, that in my little old pc (1700gzh and 1gb memory i think i have) if the cheat file is a little big, the mame takes more time for load every game, but i think that maybe exist another solution than split the cheat file in multiple little files and in special with these really rare system.

i really apreciate than the makers want to make the cheat engine better, this is good, but not in that way.

sorry my bad english and i hope you all can understand my explanation.
and i dont want to be too rude, but is the truth of the things i see.

after all, one of my dreams are play all those games i play when i are a boy and thanks for all those mame team, i can play almost all that games and i dont have words for say THANK YOU to the mame team for all those incredible work maked that mame is.


pd:
one solution for all, can be make the cheat system also compatible with the old cheat.dat files and system. and we all can use that like until now...

greetings .

[Pugsy]

I miss it more than anybody but it's gone well past the point of no-return, the cheat engine as it was has gone forever from new MAMEs along with the cheat.dat. The changes to the memory/region/cpu system mean that it's a massive task to re-add the old cheat engine/cheat.dat support.

If you still want to use the old cheat engine you have to stick with older MAMEs and forgo any new games or fixes/improvements. As it stands the new cheat engine is currently only for the cheat user rather than the cheat finder anyway - maybe some time in the future when specific cheat finding functionality is added you might feel different as it should be capable of saving new cheats in the correct xml format.

[Miguelo]

puggsy, thanks for the explanation. so if i understand fine, the core of memory adresses for the cheat codes, have been changed and now the old cheat codes dont work, even if you change it to the new cheat xml format?

oh my god... . so the convertor you make also do the needed + or - digits needed for the old code now works in the new cheat system. is that?


also, i see a very rare fails that the new cheat system caused, if i load some games, the mame crashes when i simply try to load these game, so i must erase that xml cheat file from the cheat.zip for make that the game can finally load!.
is very rare, this never happens to my with the old cheat system, is like exist conflict beetwhen the cheat and the game rom, and so the game dont loads ??.
i dont remenber what are these games right know, but this happens to my with a minimun of 2 games, maybe one can be golden axe 1...

by the way:
i have a suggestion, if you like the idea, you can upload in somewhere place of the site, the last mames emulators that supports the old cheat file system...
for example: yesterday i try to found some of them and i find nothing of nothing . you know, some time later is really hard (for not say impossible) find one of these old mame versions ).


and for end, i want to repeat that i hope i dont bother none with my commentarys . and what like you say, i also hope in the future can exist some options for be more confortable and be capable of save new cheats in this new cheat engine.

and like now i have the opportunity, i want to say THANK YOU to you puggsy, for all the work you do in the past to until now, because you make happy several people with the cheat file compilations
(and of course the same for the rest of cheat finders)

So, how do you find new cheats for the later versions of MAME that uses the new XML Cheat format, do you have to find them in the old supported Cheat.dat MAME versions and then convert them to the new format?

How do we get our hands on the cheat converter program?

Also the new built in debugger program will prove quite useful in finding more powerful cheats and other problems that people may be experiencing when using MAME. The good thing about this debugger is that you can run it in the background in it's own window while watching it in real-time simultaneously while Playing a game, incredibly amazing.

Nope, as mentioned in my other reply - use the cheat finding debugger commands.

How do we get our hands on the cheat converter program?

No plans on releasing this at the moment as it's too fluid for general use. I made it to convert a single cheat.dat file with a rigid formatting structure and special case conversions mean it gets updated pretty much every MAME release still. If you have any cheat.dat format cheats NOT already in the cheat collection that work fine and with good descriptions then I'm happy to add them.

That's useful for a single memory address watch, but I generally use F12 rather than F5.

[Seeker2002]

Ok,

first of all I'll like to thank everybody for their help, with special thanks to you Pugsy.

I was playing around with the new debug cheat engine last night and was able to figure it out with Pugsy's advise. The only problem I'm having is getting the Break Points to break at all. I know I have the correct address because I can poke the address in the memory window and it make the changes to the game, but It will not break for nothing.

I've been messing around with Donkey Kong Junior US version [dkongjr] and just trying to duplicate what's been done already so I can get the feel of the cheat engine. I searched and was able to find the memory address for infinite lives. I was able to poke the address and was able to give myself extra lives.

The address I found for infinite lives was @ 0x06228.
I tried the following commands to get it to break with no luck.

bp 0x06228

bp 0x06228, 08 == 2 <-- break when 6228 is equal to 2

bp 0x06228, 1C==03, {1C = 0A;g} <-- error it does't like the bracket but the help example shows it should? help! can't get this to work.

is anyone else having break point problems? please help

[Pugsy]

Breakpoints are used when you want to stop code running at a certain point.

What you are describing sounds more like watchpoints

So

wp 6228,1,w

Will break after the instruction that modifies 6228.

wp 6228,1,w,wpdata==02

Will break after the instruction that modifies 6228 with 02

You don't need the 0x part - the debugger assumes they are hex anyway

You don't need to do this to create RAM cheats though..

Thanks for the quick response.
Yeah, I started messing around with the watch points and got them to work thanks. The 0x works with the commands also, I'm just so use to including it, just a habit. I use to write trainers with the Evox-Team for the Xbox. I'm use to the terminology when referring to watch point that, that's just what it is a memory address used only for viewing and watching for any changes when a particular occurence or event takes place and could not be modified, whereas break points could be set to stop the program when triggered and could be set to break on a memory address or instruction.

[Pugsy]

Interesting, I had a play at making xbox trainers a few years back. But, it was a rather funless/pointless exercise as you boys had already done pretty much everything already.....damn you all!

Only game I found with no trainers was Smashing Drive but I got no where with that Couldn't even find a RAM location for time, decided then I'd wait for MESS to add XBOX emulation so I'd have access to some better tools....the wait goes on

Well, we would have been very happy to have you on our team. yeah, Dootdo was the most skilled trainer writer along with Acidflash before he started working on his own trainer project Xored. They both helped me alot with trainer writing and finding values an stuff. For that I'm forever graceful. I haven't looked at MESS yet but will when I get time, but anyway thanks for your help, much appreciated.
