[NTVDM] Start of an implementation of a software DOS emulator. Brought to you by Aleksandar Andrejevic. Good luck ;) Remove the old language files. They will be recreated when the time comes. svn path=/branches/ntvdm/; revision=59249 2013-06-17 00:00:36 +00:00			`/*`

[NTVDM] Implement all the missing INT 16h functions but 03h. Also, for simplification purposes (should be fixed later on) act exactly the same for INT 00h and 10h, and for INT 01h and 11h.

[NTVDM] DOS: Make use of get/setAX and consorts instead of EmulatorGet/SetRegister(EMULATOR_REG_AX, ...). Start to implement real (but undocumented?) behaviour according to http://www.delorie.com/djgpp/doc/rbinter/ and http://www.datadoctor.biz/fr/data_recovery_programming_book_chapter6-pageXX.html (change XX by a valid page number) and http://spike.scu.edu.au/~barry/interrupts.html svn path=/branches/ntvdm/; revision=60778 2013-10-27 22:31:53 +00:00			`#define MAX_OFFSET 0xFFFF`
