DSx86 is a DOS emulator for Nintendo DS .
Changes :
* CGA mode is forced to be blitted even if you have selected Direct mode. I believe the blitted mode is fast enough for all CGA games, and removing the direct mode made the code smaller and simpler, and there is no danger of the game stopping because of an unsupported CGA graphics opcode any more.
* TEXT mode is now also using a blitted screen copy method with a dirty buffer, so it is reasonably fast, and it too supports now all possible opcodes to access the display RAM.
* About a dozen new EGA opcodes added.
* About a dozen new DOS interrupts are supported, including some DOS internal functions that are needed by software like Norton Sysinfo, and old FCB file functions that are needed by very old games like Ultima 3.
* Fixed bugs in "!" key, DOS memory resize function, division opcode, and 0xE000 segment memory access when not mapped to an EMS page.
