RD like CnCNet at the time use 2 exe. ra95.exe is for the single player and stock skirmish and ra95-spawn.exe for the CnCNet skirmish and online play. Depending on how you are playing skirmish you may be able to grab the ra95-spawn.exe from a current CnCNet version.
You can also try using an more up to date ddraw.dll/ddraw.ini. The RedDawnConfig.exe should still work with it I think. If not you can also copy over the RedAlertConfig.exe and rename it too.
Far as I know the ra95.exe I use was edited by Iran and has code that wasn't ever ported to the CnCNet .exes so It can't be change/updated as it would break things in the single player missions.
Maybe an update of the ddraw.dll/ddraw.ini. would fix menu problem. As for saving skirmish games bugs. This may have been a bug from back than as the stock game didn't let you save skirmish games and it may have been fixed in the last 9-ish years.
