I commend you for obtaining your ROM from your own machine.

But if your Donkey Kong ROM works in current MAME it will not work with MAME4ALL that RetroPie uses. MAME4ALL is based on an older version of MAME and the ROMs are (sometimes) different. I know for sure Donkey Kong is one of the ROMs that is different.

I posted a new WIKI article on checking your ROMs, I would suggest you read through it.
