Emulator Cheats

Thanks Pugsy, that was the problem.

I was using an old cheat.dat file, which didn't work at all using the new cheat engine. But now with the cheat112 file, all seems to be ok.

0.113 doesn't work for me. I haven't tried 0.113u1 yet though.


Is there any documentation on the new changes?

Thanks,

Kranser.

I cannot search for cheats in MAME 0.112 & 0.113, as the menu option is missing from the cheat menu.

Has this functionality changed, or is it just broken?

Thanks for any help.

Don't worry! I found the cheats in the unofficial cheat.dat!!!

Powerbal/powerbls (Power Ball)

Can anyone find a cheat that will cause the ball to always be in play (i.e. never die), or alternatively one that causes the current level to be cleared.

Thanks,

Actually, weapons and special point items flash rapidly between 3 different colours when they appear on the screen, causing them to appear "blinking". So, gng probably doesn't have the capability to have more than 1 such object flashing at a time. However, it should still be possible to in...

Hi, Anyone know Ghosts'n Goblins well enough to know whether this cheat is possible (or even be able to implement it!). To enable enemies to carry weapon/treasure bags even when a weapon/treasure item dropped from a bag is on screen and hasn't been picked up. This may not be possible if the game use...

I think it's a good idea, as long as it will be relatively easy to add cheats to a lot of games for 'Randomise Gameplay', assuming that the factor which determines play (time, score, etc...) can be determined. Sometimes, NVRAM plays a part in gameplay - I don't know if it's possible to randomise NVR...

Of course, if your cheat.dat file is too large, you probably have too many games in it. Most people do not use every game in MAME, therefore by stripping out all the games you don't own/play, the cheat.dat file could be a lot more manageable. Maybe we could have a program which renames cheat.dat, an...

Another use for an 'IF' cheat feature would be when implementing level-specific cheats. I.e. Fixed Memory locations which mean A in level 1 (e.g.) and B in level 2. This could be good for controlling the end of level bosses in say GNG, as each end of level boss seems to use a fixed memory location w...

Well, Cheat 'IFs' would be useful for adding a fixed amount of time to a level (in say, gng or lemmings), without crashing the game (or causing display errors) if the amount went over the maximum that the game can comfortably cope with. It would be good if a menory address could be tested with a con...

Thanks Steph. Yep, I did mean 00!

I don't think the 'Level x Next' and 'Level x Now' are needed anyway, as these only work for Stage A!

Well, this cheat gives unlimited time, and takes away the "time" aspect of completing each level as quickly as possible. The cheat I'm trying to make will give you additional bonus time after each level is completed. The Arcade game gives 3 minues initial time + 2 minutes bonus time (given...

Yes, I done some more testing, and found that it is probably due to the time being greater than the allowed maximum time. Does anyone know where the extra time amount is stored? I guess, we just need to set this to a lower value, as well as executing the above cheat code. The current extra time is 2...

I found the following cheat for Lemmings: lemmings:0:10A3B3:00:000:1UP Always earn Extra time However, after earning extra time from the second level, the game crashes. Could this be due to the time being greater than the expected value? And, if that is the cause, does anyone know how we could limit...

Hi Steph, I now have the codes for pbobbl2n & pbobbl2x - they weren't that difficult to find (maybe the same programmers programmed the Neo-Geo version!). Here are the codes for pbobbl2n: pbobbl2n:0:000000:00:999:[ Codes - Puzzle game ] ; Path is coded on 1 byte (00-1Ah) : ; 00h ("A") ...

I've just realised that I got confused. I thought that your comment lines was the "new cheat engine" method for including 999 descriptions! You didn't mention whether you've got anything for the pbobbl2x & pbobbl2n games - these use different memory addresses, and will need the cheats ...

Thanks for your cheats Steph! I'll have fun testing those! They sound more complete than the ones that I found. And you've managed to determine which of the "round" addresses do not need to be set -thanks. Do you have these cheats for pbobbl2n & pbobbl2x? If not let me know, and I'll t...
