Emulator Cheats

Posted: **Sun Nov 24, 2019 3:21 am**

Here is a cheat I was working on, it is a Training Mode - Player Actions for SF2CE based on the POF Training Mode for ssf2.

The Player Action Padlock, makes the player move with predetermined actions, such as jumping or covering, so that you can practice and train.

Thanks to the excellent documentation that I found in this forum, and to the guide of our friend POF that he left written in his blog, I was able to complete this contribution, since searching on the Internet I did not find any training mode for SF2CE. This Cheat XML has been tested without problems in Mame 0.215. Although the script still has some errors in the "fierce throw", since the player is not yet able to grab, so if someone found a solution I would be very grateful. A big SF2CE fan says goodbye.

Best regards

Hi Fernando, thanks you!, the cheat you put is very interesting. The truth is that I am still a newbie in the unpacking of a rom, but when I have time I will try to look for victory poses, what I can think of is to look at the end of each game, just when they are activated.

Best regards

I need your help: could you figure out how to activate victory poses during the fight without interrupting it? Thanks a lot if you can find out and if you have any new code post here please! I will leave a code below as a thank you! God bless you! Fernando M. Hack

Thank you for the excellent cheat, if you had downloaded some cheats that have similar functionalities from http://cheat.retrogames.com/mame_downloads.htm, in the sf2ce.xml file that is included. What difference is there from your cheat, with respect to the cheats included in sf2ce.xml?

Best Regards

Hi chunli_fm_hack, thanks for reminding me that I had this doubt pending, currently what I have managed to find in the MAME debugger by debugging the FF8650 address, in the first 2 bytes (FF8650-FF8651)

The scheme would be as follows:

Code: Select all

A is left nibble value from FF8650 address memory
B is right nibble value from FF8650 address memory
C -> left nibble from FF8651
D -> right nibble from FF8651

D value:
Right = 1
Left = 2
Down = 4
Up = 8

C value:
Small punch = 1
Middle punch = 2
Strong punch = 4

B value:
Small kick = 1
Middle kick = 2
Strong kick = 4

Example:

1) It is a movement to the left and strong punch
A B C D
0 0 4 2

2) It's a movement to the right and middle kick
A B C D
0 2 0 1

Let's see if we can solve the problem because the automatic grip does not work.

Just in case the memory address for player 2 is: FF8950

Best Regards

Thanks chunli_fm_hack, it is just my next challenge to make macros for sf2 players, to see if we are doing it together. I have corrected my previous post, where I responded, a minor error corrected.

Excellent chunli_fm_hack, in theory it should work, but I could not, it has the same bug that has the first code I put, which I still don't know what it is. That is, the player only moves, but does not simulate pressing the button. Have you testing the code? in which version of MAME, I am testing it in MAME 0.215.

Best regards.
