ENG - So why don't add a suitable menu in mame debugger insted of using the command line ?

ITA - Allora perche'non aggiungere un comodo menu direttamente nel mame debugger invece di utilizzare la linea di comando ?

Thank you very much ronco ! Ma sei italiano ?

Do you think it can be implemented inside the mame ingame menu (TAB) ?

WOW ! I was momentanely out of the scene ! GREAT NEW ! Is there someone here able to explain how to activate/use it under the mame debug ? Thank you !!

In this new mame version (0.134) the mission cheat seems not to work correctly, in particular it seems that the cheat engine DO NOT POKE the value to memory using the max min parameters... anyway levels are 10, starting from 0 (=mission 1) to 9 (=mission 10) so the cheat must be rewritten selecting ...

I don't know why but in the 0.134 version the mission cheat seems not to work. I think you can check it even without the chd, the game should start w...

This is the correct cheat, last level is 10 and not 9. <cheat desc="Select Mission"> <parameter min="0" max="10" step="1"/> <script state="run"> <action>maincpu.pb@01096=(param-1)</action> </script> </cheat>

Select mission cheat: <cheat desc="Select Mission"> <parameter min="0" max="9" step="1"/> <script state="run"> <action>maincpu.pb@01096=(param-1)</action> </script> </cheat> Missions are 10 in total, from 0 to 9, but I am still not able to complete t...

many thanks to Pugsy for his great previous help !

To find cheats without the mame built-in engine (that is not present at the moment in the mame releases) you must: 1) Run mame in debug mode (at the command line or in a batch file write mame.exe -debug or mame32ui.exe -debug if you use the win32 version), choose the game and hit F5 to start it. 2) ...

Infinite lives:

Infinite Lives & no overheat of the main cannon. This last cheat produce a little bug ("hit sprite " persists on the screen until you hit another enemy). Tested with mame 0.133. I am currently looking for a "mission select" cheat... I think I will investigate it further in th...
