My MAME 0.279 is currently in a state where if I start Mr. Do!, it will do the auto complete bug from the start and I presume forever (I let it run until stage 270). I would be happy to send any files if it would be interesting to the devs. I presume this is an issue where you have selected in the ...

I'm trying to develop a LUA script to take action based on a memory address in a game. Specifically, Area 51, and I'm looking at the ammunition count. I've determined this lives in the maincpu program space at address 0x9000876F. If I run the debugger, start a game, then run the debug command print...

i see there are many consoles in mame but they say cartridge. how to do you set up mame to play those games are where can i get the cartridges to download? do i put the cartridges in the roms folder? I'll try to break it down as best as possible. Assuming your MAME setup is installed in C:\MAME fol...

Well in Mame Version 0.275 when some cheats like invincibility no longer work. Now using the same rom and cheat database in Mame version 0.264 all the cheats work as normal. I wonder if there is a fix, so the cheats work in 0.275? Entirely possible there was a region name change and the cheats refe...

Another error I noticed in the games Mortal Kombat 2, 3, Ultimate 3, WWF Wrestlemania, and NBA Jam is that the sound is very low compared to other games. This is simply an issue with the setup. You need to go into the machine's service mode and adjust the volume, just like the original arcade game ...

What is the quality of the fullset mame mame 0.260 dumps? Are there still many bugs and errors? MAME tends to always trying to maintain the best, currently available romset which is reflected in the releases done. In other words, despite older romsets being updated or changed, the latest version is...

So I've found a bootleg ROM for the arcade SF2: The World Warrior that replaces sf2jh.zip. It's a boss hack of the original Japanese version and seems to be somewhat widespread with a bunch of YouTube videos showing gameplay from it. When I replace sf2jh.zip with it and run it from the commandline ...

Hello MAME Folks, I've been using your stuff since the late 1990's. Thank you :-) More recently, I have been looking into interprocess communication between MAME's Lua scripting and the OS (Happens to be Python under Windows 10). I haven't found much in the way of working examples. Can you recommen...

I am just looking for documentation on writing drivers. PDF or video maybe. Things like: Do you print to the console to help debug. Is there a working step debugging setup I could try. Maybe a walk through? I found something around here about creating space invaders, but it appears it isn't finishe...
