Ok, here's a down and dirty way to zero out the number of times a game has been played. I can not stress the following enough:
BACKUP YOUR MALA FOLDER BEFORE CONTINUING. I would feel very badly if you corrupted your gamelist(s) by following my method.
I HAVE TRIED THIS ON Mala 162g ONLY! Also, I have only tried this with custom game lists for MAME. I have not tried the Mame Main Game List The procedure will be slightly different for other emulator lists. Especially those with roms that do not have a ZIP extension. Do not try this on non-Mame gamelists!
Step 1. Download the hex editor XVI32, here:

Step 3. Using the hex editor, open the game list that you want to zero the number of times played.
Step 4. Click Search at the top, then click replace.
Step 5. Change all options and settings to exactly what I have in the screenshot below. If it is not
exact, you will corrupt your gamelist.
Step 6. Click Replace All
Step 7. Save it. That's it. Good Luck!
If it doesn't work for you, zip up your (original- not a corrupted) game list and email it to me. PM me for my email address.
