Setting up a Ipac2

Riverstorm

This is cheating a little, as your ROMs should obviously align with MAME set required, but many classics don't change from set to set.

I wouldn't call it cheating at all! ;) I have 250+ games in mame4all and mame2003 folders. If I compare them as binary they are almost 100% identical directories. On top of that if you TorrentZip your sets they'll have the exact same hash and are 100% identical except for the half dozen or so not supported in mame4all.

I had to go through a bunch of the defaults and set them ="nul" in order to prevent them from overlapping the standard IPAC/MAME mapping above.

Where would I go about's setting defaults to nul? Is that in the menu (tab key) once inside a rom?

@kombat You would be better starting your own thread with a specific question but the answer is no. Are you referring to TAB in MAME? that is how you can make changes but with regard to setting up the keyboard encode you need to read through https://retropie.org.uk/docs/RetroArch-Configuration/#hardcoded-configurations

@kombat - If you're using mame2003 there's a version named mame2003-plus in the Experimental section of the RetroPie setup menu. It has options under Quick Menu/Options once in a game to completely ignore TAB inputs. It might save you from needing to 'nul' every input. It's basically the same core with around 130 additional games and some other improvements. It's Experimental but solid. You can report any issues on the Github page.

I'm good with my keyboard encode, my question was in regards to @caver01 setting defaults to null as I am having some similar (i think) issues where the emulator defaults are conflicting with my standard IPAC/MAME mapping (example my player 2 button 6 is triggering a fast-forward?). I am wondering where I can access those settings

By editing the file as shown in the link I posted. You need to access it via SSH.

@kombat Yes, the link above that rbaker provided will lead you to a description of /opt/retropie/configs/all/retroarch.cfg which is the global config for retroarch. Inside that file, i set funtions to "nul" that I am not using. I seem to recall needing to do this for overlapping keys on mine as well. Fast foward was one of them as I recall.

As for setting ALL player inputs to "nul" globally--this is NOT what I have done in the past. I only ever did that for a couple of games using rom-specific configs. For example I placed a file into my ROMs folder next to the game rom for vidicators using the format: romname.zip.cfg such that the romname matches. In this file I set all player inputs to "nul" so that I could use the MAME GUI menu <TAB> to define the unusual <CODE_NOT> mapping for a tankstick setup. This is highly unusual, as only a few games require that. I don't rely on this globally because some retroarch emulators don't have a <TAB> feature. FBA for instance won't get very far if you NUL all of your player inputs!

@AndersHP Hello. I’m new to manually editing Config ALL and have been using TextEdit on Mac. What do you mean that it left the inputs dead? What’s the difference with TextWrangler? Thanks!

@DetroitKp
Hi, I'm no coder, but there's a difference between curly quotes and non-curly ones.
TextEdit uses the curly quotes, which in coding I guess is wrong.

See here.

My recommendation is to use TextWrangler - it's free and a much better tool than TextEdit.

I am replying to this topic in the hope that somebody sees this and can help me. Fantastic bit of info on here which has helped me enormously. The only thing I have an issue with is setting up my hot keys in the all retroarch.cfg file. I cant seem to find anywhere that enables me to edit the hotkeys. This is really important as I have a 2 player setup, each with a joystick, 6 in game buttons each (a,b,x,y,l,r) and a start button each. I cant seem to find a section in the config file that allows to set the exit game/exit emulator or pause hotkeys.

Can anybody help?
