(DOS for NDS) DSx86 LW2 - 模擬器

2009.11.23

Currently DSx86 emulates the following:

- 80186 processor (which is actually a 80286 processor without
the protected mode stuff)
- MCGA graphics adapter (a stripped-down VGA with a maximum
resolution of 320×200)
- SoundBlaster (including AdLib-compatible FM sounds) sound card
- 83-key US keyboard

DSx86_LW2 is a technical demonstration of my PC emulator for
Nintendo DS. Since the actual emulator is still very limited in
the opcodes, DOS calls and hardware it can support, I can not
release a version that would allow you to test any DOS program
on it (as with a 99.9% probability they wouldn’t work).

The only two programs my emulator currently runs are Wing
Commander 2 by Origin, and my own old DOS game LineWars II. Of
course Wing Commander 2 is copyrighted material so I can not
include it, and since releasing a demo that does nothing useful
unless you have purchased a certain game nearly 20 years ago is
not very smart, I’ll release the demo version bundled with my LW2.

The size of the nds file is about 627 kilobytes, of which 224
kilobytes is taken by LineWars II (11 KB for the LW2.COM loader
and 214KB by the LW2R.DAT data file), and the rest by the
emulator core itself.

The demo begins at the start of the LW2.COM code inside an
inbuilt x86 debugger. You can run it either by pressing the B
button on your Nintendo DS, or by using the touchpad and
clicking on the G on the low left corner followed by the v
symbol (meaning “Enter”). When the demo starts, use the
shoulder L and R buttons to scroll the screen, so that you
can see the whole 320×200 graphics screen or the 80×25 text
screen. One interesting info you might want to check out is
the framerate counter on the right bottom of the LineWars II
game screen (after you have launched into a game).

Feel free to play around in the debugger if you wish, and you
can also break into the debugger at any time when the game is
running by clicking on the Close (X) button on the virtual
keyboard in the touchpad. Please note, though, the inbuilt
debugger is meant just for my development aid, and therefore
is read-only and not very feature-rich.

If the demo breaks into the debugger by itself, it means it
ran into an opcode that is not yet supported. There is no way
to continue after this has happened, so just reboot and start over.
