Emulator Cheats

Some quick RAM cheats for this game that was recently fixed: polynetw.xml <mamecheat version="1"> <cheat desc="Infinite Credits"> <script state="run"> <action>maincpu.ppb@FF9FEA=63</action> </script> </cheat> <cheat desc="Infinite Time"> <script state="on...

Thanks for the spot, I've fixed them for the next release.

Just noticed cheats for this have been posted already (doh!)...but these do differ, the firemen "invincibility" here is simpler and there's a cheat to stop fire spreading and cheats for the 3 ways of finishing the level. megrescu.xml:- <mamecheat version="1"> <cheat desc="In...

Thanks, that's sorted it.

Quick one, try this: <cheat desc="Sound Test Timer Stop"> <comment>Press the P2 button to increase the sound number</comment> <script state="on"> <action>temp0 =maincpu.mb@27ECD</action> </script> <script state="run"> <action>maincpu.mb@27ECD=B6</action> </script> <scri...

85C7480/8 or simply 10B8E90 is the lives address - 85C7480 is the address you posted above.

59F38 is the program code address for invincibility (not what you asked for - and unrelated to infinite lives).

@crazyc I am running through some tests for the next cheat file update, there seems to be a problem with 'height' in the json/lua hitbox viewer cheats. error cheat script error: "Hitbox viewer" [string "Hitbox vieweron"]:223: attempt to call a number value (method 'height') So fa...

Midway games memory can be odd for sure

Try dividing the address found by 8...

Try :-

And as a side note, just knocked up a quick ROM Invincibility for what it's worth...

These will make the game a breeze to complete:- timetrv.xml:- <mamecheat version="1"> <cheat desc="Infinite Lives"> <script state="run"> <action>maincpu.ppb@00794=09</action> </script> </cheat> <cheat desc="Auto Complete"> <comment>You don't have to do anythin...

I'm sorry if you are using cheat.dat then the version of MAME you are using was released over 13 years ago (at least). The reason you are missing lots of files is because you are missing lots of files. Lots of games have been dumped/redumped over the last 13 years and romsets have changed names. The...

KelvSYC made a load of movelist cheats years ago, I converted them into XML format back in 2010. I've said before as they stand they are not going to get readded to the cheat file. You can of course just add cheatmlc to the cheat path In mame.ini change cheatpath cheat; to cheatpath cheat;cheatmlc a...

I've been busy/occupied with real life stuff unfortunately. I was planning on a release before christmas but I lost interest due to a one sided discussion which made me question why I bother - so I didn't. I'm still considering what the best way forward is. Spambots got through as I'd left the gmail...

DIP switches are bit related so you'd need to poke it with a mask, so something like this:-

maincpu.pb@100001=40|(maincpu.pb@100001 BAND ~40)

However, if it doesn't work with universe bios it's probably wont work with a MAME cheat either.

No, the cheat collection is included as part of Duckstation. If you have Duckstation then you already have the cheats.

I've added the capability of firing over land and fixed a bug so you to die when you run out of fuel to the above. There's no need to add Infinite Energy to it as it exists seperately.

Here's a better ROM Invincibility, you can still pick up fuel with this cheat. Whoever hacked the ROM did a dirty hack for that cheat as it just changes the zero page address stores to another address. <cheat desc="Invincibility"> <comment>Don't run out of fuel/energy - so enable the infin...

Ok, had a look at Invincibility. Sprite/sprite collision code is around a3b6 and sprite background is around a3fc. <cheat desc="Invincibility"> <comment>Don't run out of fuel/energy - so enable the infinite cheat for the best effect</comment> <script state="on"> <action>temp0 =ca...

Knocked up some quick cheats, use these in the cheat.simple file with the plugin cheat engine. I will convert them into XML cheats for the next release. ddpsdoj,:maincpu,C1E112F,b,9,Infinite Credits ddpsdoj,:maincpu,C5F9973,b,8,P1 Infinite Lives ddpsdoj,:maincpu,C5F9976,b,6,P1 Infinite Bombs ddpsdoj...

A quick glance at the cheats and notice that you are Binary ANDing a word value with byte value, this wont work as you may have intended..
eg 140 is wrong for pb value, it should be between 01 to FF
maincpu.pb@00AF BAND 140

Sorry about hijacking the thread, the notes about the Invincibility tickled my interest.... <cheat desc="Invincibility"> <comment>Dont run out of energy with this enabled or you will get stuck</comment> <script state="on"> <action>temp0 =cartleft:cart:rom.mb@5EC0</action> <action...
