DS2x86 by Patrick Aalto is a PC emulator for Nintendo DS. It’s purpose is to allow you to run old DOS games on your Nintendo DS game console. DS2x86 is a port of DSx86 port using the SuperCard DSTwo’s MIPS processor, therefor it will just run with such a card.

Changes:

– Blinking cursor in text modes (finally!).
– HIMEM.SYS emulation added, allows Chaos Engine to run.
– Fixed a serious total crash problem in 32-bit string opcodes.
– Fixed a stack alignment problem that could cause “Exception 4” BSOD errors.
– Improved BSOD reporting, now includes a stack trace.
– Improved horizontal blank reporting, this might solve hanging problems
in some games.
– Improved Mode-X graphics blitting code to handle wrap-around properly.
– Changed the screen refresh interrupt interval from 60Hz to 59Hz. This
might help with the intermittent “stuck key” problem in some games.
– Direct file read to EGA memory is now supported (f.ex. in “Heimdall”).
– Implemented a number of previously missing opcodes.
