Nice tutorial Pugsy. Think you could make one using the debugger to increase lives instead of decrease on death (change DEC to INC/SBC to ADC)? I know the ASM is processor specific but the method should be universal for the most part. I am most likely going to start the trek of mame debugging next week on my vacation so all/any help is appreciated.
Bored? Watch some of my hacks here. Wanna hack like me? Use Branch Finder. Looking for hidden menus, characters, etc... in your games? Use The Peeper.

Pugsy

will you continue the tutorials for us to search and learn for every kind of codes?

for example

how we can find invisibility
how we can find all weapons
how we can find all ammo
how we can find infinite time?
how we can find "no crushing" with other cars?
how we can find automatic firing?

etc

For flickering Invincibility, when you are flickering open the debugger, and issue these commands in order:-

1. ci
2. gv
3. gv
4. cn -
5. gv
6. cn -,1

then repeat 5 + 6 till you have only a few addresses to check

I searched everywhere on the net a complete tutorial on "how to" use the mame cheat engine, impossible to find (even here).
There is only the basic "infinite lives"
So i am asking how you can find all these cheats wrote in the xml's.....
