A few days ago version 0.4 released, and would not comment if I get many positive changes in this emulator. If you want to know what new features brings...
Fixed EGA palette handling that got broken in the 0.04 version. Sorry!
Added hardware mouse cursor support in graphics modes.
Added options to adjust screen overscan values.
Added (experimental) support for running rpix86 under X Window system.
Added command line option -a2 to start rpix86 with no audio.
Added JPO and JPE opcode special handling for Chess Genius 3 DOS version by Richard Lang.
Fixed bugs in several JPO and JPE game-specific opcode handlers.
