Autozip in MAME

--------------------------------
1. Install 7-zip and copy the "7-Zip" folder from Program Files to your MAME directory
https://www.7-zip.org/download.html
--------------------------------

--------------------------------
2. Copy below and save as 'zip.bat' in your MAME directory
--------------------------------
SET CURRENTDATE=%DATE:~10,4%%DATE:~7,2%%DATE:~4,2%
SET CURRENTTIME=%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
SET ZIP="%cd%\inp\%1-%CURRENTDATE%-%CURRENTTIME%.zip"
"%cd%\7-Zip\7z.exe" a -tzip %ZIP% "%cd%\inp\%1.inp" > nul

--------------------------------
3. Add the following to the bottom for your 'record.bat' file
--------------------------------
zip.bat %1


---------------------------------
Example record.bat file
Note. I change the %2 in the line that calls MAME to %1 (after -record)
This means I don't need two arguments from command line (i.e. record dkong, instead of record dkong dkong)
---------------------------------
@echo off

if exist nvram\%1.nv move nvram\%1.nv nvram\%1.bak
