Emulator Cheats

The games that do not work are marked accordingly. A full (ish) list of new games can be found in the whatsnew.txt file included with MAME.

Very true. Another example: In Lightbringer, it is possible to select which entry in a large object table is used for the main player. However, only the four main characters have code connecting the joystick inputs with movement, etc. The rest of the objects behave as their AI tells them to do - you...

Very nice. Congrats on the release.

One small comment though: right now the file includes an underscore command to disable the labels in advaned cheat search mode - was this intended?

As requested, I've expanded the force range cheat type to add support for >8 bit writes.

Q: The "mapped memory" type I'm using doesn't have a CPU parameter listed in the UI? Fixed. Change line 3594 from if(locationType == kLocation_Standard) to if((locationType == kLocation_Standard) || (locationType == kLocation_HandlerMemory)) What do I need to do to make this work? Fixed. ...

Sample code? Please elaborate.

Both cheats would be treated as a no-op.

The "ignore mask" flag was being set incorrectly. Fixed . Also, change displaytext in usrintrf.c to this to fix the missing-highlight bug: void displaytext(struct mame_bitmap *bitmap, const struct DisplayText *dt) { /* loop until we run out of descriptors */ for ( ; dt->text; dt++) { ui_te...

I don't think the MAME debugger can read memory areas that aren't directly mapped either. Or at least, explain how Bugster got the cheats for selecting the line of opponents in Dramatic mode in sfa3... Possibly by adding a few lines of code to src/vidhrdw/cps1.c to dump REGION_USER1 after the xor'in...

Sounds interesting, but I'm not entirely sure how useful exporting/importing XML would be.

But seriously, what's the big differense between that emulator I used and the MAME, when talking about KI and KI2? Accuracy. The other emulator takes shortcuts to achieve faster emulation. It is also a standalone emulator, so the code can be optimized for a specific game, unlike MAME, which is opti...

What are the requirements for KI and KI2? More than twice the processor speed you have. What slows down the game ?! Blitter-based graphics hardware, a fast main CPU, and the Midway sound system. (Earlier I used another emulator 2 play KI games - with no problems whatsoever). That emulator is substa...

Blank page...?

Hmm. Seems slightly useful, but it would require more dynamic memory than I want in the loader. That and right now most of my MAME-coding time is spent making the PPC talk to the SHARC & the SHARC talk to the 3D.

Thanks for sending me the code - and now to make Apache and PHP start talking to each other...

Sounds like a good idea - if there is some sort of access restriction on who can add cheats. Preferably, there should be a general-case submission form (for random people finding cheats) that would require approval from one of us before addition to the master file, with the ability to log in and byp...

Ian, can you give insight to this matter? The watchpoint system doesn't use the same input handlers as the rest of the cheat engine. The only real barrier to fixing this is the need to display all the parameters needed for full custom watchpoints, essentially reimplementing the "edit cheat&quo...
