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:

– FPU support! Only in 32-bit protected mode, and not all opcodes are yet completely supported, though.
– Fixed an unaligned memory access crash in EMS function 0x57 (Aladdin)
– Built with SDK version 0.13, which hopefully helps with the audio problems in the previous version. I had not noticed I still used older SDK version.
– Compiled with flag -no-long-jumps, which makes the C code smaller & faster.
