10 // Who When What
11 // --- ---------- -----------------------------------------------------------
12 // JLH 12/23/2009 Created this file
13 // JLH 01/21/2011 Added SDL initialization
14 // JLH 06/26/2011 Added fix to keep SDL from hijacking main() on win32
15 // JLH 05/24/2012 Added option switches
16 // JLH 03/05/2013 Fixed console redireciton on win32 platform :-P
17 // JPM 06/06/2016 Visual Studio support
18 // JPM 06/19/2016 Soft debugger support (--debugger)
19 // JPM 09/ /2017 Added option (--dram-max) to support 8MB ram (which doesn't exist)
20 // JPM 09/06/2017 Added the 'Rx' word to the emulator name and updated the credits line
21 // JPM 09/08/2017 Added option (--es-all, --es-ui, --es-alpine & --es-debugger) to support the erase settings
