[Mame] Software: NES Question, Is it possible to have per game cfg settings rather than per system settings?

[tkssitch]

As, title says.  I know Mame isn't the best for console emulation, but I have specific purpose for using mame.  I when I [Tab] into in-game menu, the changes are saved on a system basis [nes].  I'm looking to save them (if possible) on a per game as you can the regular arcade.  Thanks, all feedback appreciated.

You'd need to add -statename to the command-line parameters.  The full command would be:

"D:\Mame\mame.exe" nes -statename nes/addfam -ui_active addfam

Then in LaunchBox for your NES Associated Platform:

nes -statename nes/%romfilename% -ui_active

I add ui_active so the keyboard works normally.  Alternately, you can set in mame.ini (or nes.ini).

Oh snap!  I was thinking save states.

For per game configurations, you'd use  -cfg_directory "

D:\MAME\mame.exe" nes -cfg_directory "D:\MAME\cfg\nes\addfam" addfam

Or

nes -cfg_directory cfg\nes\%romfilename%

Actually, have another question that goes to the save state, this would be for use on regular mame arcade games.  How would i use it from a command-line to boot into a mame starting at a save state? Thanks!

Universal Command-line Options — MAME Documentation 0.273 documentation

-state <slot>

Immediately after starting the specified system, will cause the save state in the specified <slot> to be loaded.

Example:
mame -state 1
