mameCfg

https://retropie.org.uk/forum/topic/32159/mame2003-default-cfg

mame cfg settings files

Always end with .cfg
Always stored in a mame2003\cfg\ folder under roms share.
In roms share under roms\mame-librettro scattered all over (never in config share)
Always stored in binary not text, so not human readable.

default.cfg

Mame General Settings are always stored in default.cfg
default.cfg always start with MAMEDEF at start of file.
These are per rom dir, so there is no true General Mame Settings file that I can find.
/romdir/mame2003/cfg/default.cfg
I have 26 of these on Centipede. I doubt I have one in each dir, so I doubt there are any truly general settings anywhere for mame config.
Always 9kb (+3 Times larger than title.cfg files.
UI Select and Cancel can be changed in this file only. NOT in title.cfg.
Has Trackball, Pedal, Lightgun, Paddle, P1-P9 controls. Every possible control ever invented are in here, which is why the default.cfg is so much larger than any title.cfg
To truly make global we would need to replicate this file across every single rom dir.

title.cfg

Per Game Override Settings are stored in these.
Match rom title name in /mame2003/cfg subdir of rom.
1-3kb (Smaller than default.cfg)
Always start with MAMECFG at start of file.

Was wondering if Retropad1 A and Retropad1B meant anything from Retroarch. They do NOT. In mame Menu A means Button4, B Means Button1. Has nothing to do with any remapping in retroarch or any where else

Retroarch Remaps to Mame

AutoSave

Every time we launch a game if no title.cfg and default.cfg exist they will be created. Since I have lots of subdirs this makes quite the mess. Some of my default.cfg files are 5 years old. So on a fresh system it's probably a good idea to clean these out. Once we get a default.cfg good for one a1up we need to propage it across all subdirs, then tweak accordingly.

Need a script that scans all rom dirs and

List dirs missing a default.cfg
Verifys settings against some std default.cfg they need to match.

At most I want two std. One for Spinner/Tball and one for Jstick.

These are a better way to do Button Overrides since these should not screw with UI Select and UI Cancel.
