I am running VPA (VPA-V383) on a Mac (Intel) with osx and Dosbox. Everyting works as expected, except of "General protection fault error (Error address is 0017:04F4)" during exiting the application (Alt+x or Alt+Ctrl+x) right after Making trn step. The TRN file is created, but I don't know is it correct or not. Please take a look at this issue.
