Take your time, no rush.

Easy/Hard is dependent on the user. If you are familar with the mame source code, it would be relatively easy although maybe a bit time consuming for you to add it into the source code.
If you are expecting it to happen in official Mame, I highly doubt it will happen. From my quick look, this seems to be one of the only drivers in all of the source code that they are doing something like this and seems like they are doing it for this one game on purpose. This also seems to be our only way of getting them to change it in official Mame. Luckily, captainpotato has stepped up to the plate.
