For custom ports, added the ability to specify a compatible port - in this case, when starting the custom port, the command line parameters of the compatible port will be used
Added support for source port DSDA-Doom
Added command line parameter '-help' (as well as '-?' or '?') - shows a list of all supported parameters and allows you to select any of them
Command line parameters can be abbreviated to one letter (first), and you can also use the '/' character instead of '-'
