DSx86 definition ：
DSx86 is a PC emulator for Nintendo DS,by which you enable to run old DOS games on your Nintendo DS game console,and it's the DOS emulator for the Supercard DStwo.
Here is the original detailed information quote :
1)Preliminary support for high resolution EGA/VGA modes 640x200, 640x350 and 640x480 added. NOTE! Scaling does not work properly in these modes yet.
2)Implemented preliminary support for Mode-X mode 360x240 (for the Settlers game).
3) Implemented a lot of missing opcode variations, now a majority of the most common opcodes have been implemented, but many rare opcodes are still missing.
4) Increased the EMS memory size to 4MB, which allows Elder Scrolls: Arena to start up.
5)You can now switch between the configuration sections in the INI file on-the-fly, by clicking on the current configuration name.
6)Fixed a stack alignment problem in overlay loading, which caused an "Exception 5" error in some programs.
7) Fixed a bug in SETZ opcode, which caused Warcraft to hang when giving a command to dig gold. NOTE! It is recommended that you play Warcraft with "no sound", as the SoundBlaster emulation in DS2x86 seems to cause intermittent freezes and crashes.
8)Fixed a bug in division-by-zero interrupt handling, which caused Formula One: Grand Prix to fail.
