Older version I had downloaded from before needed this to be copied into a text file but the new downloads has a dosbox launcher to set in an option menu but yeah stupid me for not seeing it.

Had someone message me the fix no need to help anymore.

Thanks for sharing the solution so everyone will benefit from it.

Don't be so selfish...
