These hacks could no longer be allowed to co-opt the fake multiplayer mode, used for local testing and mod development. I have half a mind to remove the hacks outright because they could be likened to drilling bolts directly into your car engine just so you could mount a bowling ball as a hood ornament. However, I don't want to take away the splitscreen hack mod from anyone who uses it, and the work done on these hacks should be useful if proper splitscreen were implemented internally using per-player input and multiple renderer/audio passes. git-svn-id: https://svn.eduke32.com/eduke32@4249 1a8010ca-5511-0410-912e-c29ae57300e0
