You can always try a command like this to show files changed in last 5 mins.
find /home -type f -mmin -5
Thanks. The find command was most helpful and I'll be sure to use it with any similar issues moving forward. It turns out that the location is not hardcoded and that a 'mame2003' folder is generated within whatever folder you have your roms. I keep the Mame 0.78 rom set in a folder inside the 'arcade' folder, so bingo bango, there it was.
Thanks again.
