DSx86 v0.20

[granville]

DSx86 is an Intel x86 emulator for the Nintendo DS. It aims to replicate the x86 computer architecture on DS as accurately as possible. It has received an update in the form of beta version 0.20. The author skipped directly from 0.15 to 0.20. Change log and download below. [/p]

[titleSx86 v0.20 beta Change Log]
• New IRQ handling using self-modifying code, which makes the whole emulator about 8% faster than before. More info in my previous blog post.
• Keyboard handling changed to support extended key codes. This will allow the mapping of some new keys like the right control key to an NDS button. Again more info in my previous blog post.
• Screen update mode "Direct" was removed. It was only used in the MCGA mode, and it only speeded up certain games (Wing Commander series, mostly) by a small amount. Having that mode around meant I had to write double code for all MCGA/VGA graphics memory and BIOS operations, so now I finally got fed up with doing that.
• AdLib emulation changed from effective 13-bit waveforms to 15-bit waveforms (and full 16-bit with rhythm instruments), which means that AdLib audio now has quadruple volume.
• AdLib rhythm instruments (Bass Drum, Snare, HiHat, TomTom, Cymbal) implemented.
• Covox/Disney Sound Source/Parallel port DAC audio device emulation added. Thanks sverx for the idea!
• Sound Blaster Direct DAC audio output mode supported (SB DSP command 10).
• Sound Blaster auto-init 8bit DMA audio output mode supported (SB DSP commands 1C, 48 and DA).
• Fixed the BLASTER environment variable to state the SB type as T3 (SB 2.0) instead of T4 (SB Pro 2.0), as only mono audio is supported. Some games (Hocus Pocus, for example) attempted to use stereo FM sound when the type was T4, resulting in no AdLib audio.
• Graphics problems in Gods are fixed.
• Some new EGA opcodes added.

Pure DOS commands like dir, tree, del, copy, move and stuff.

I`ve just set up everything, including 4DOS shell, and worked great, at least loads main bumpy`s splash screen.

It`s a DOS emu basically.

Tried running win3.11 with no luck u-u (i own those diskettes ahahaha, :old:, really)

It only emulates a 186 (a 286 without protected mode, but as there is no easy way to switch back to real mode until the 386 very few things used 286 protected mode). If you want to run Windows, Windows 2.03 is working perfectly as long as you use setver (or ver set ) to set the DOS version to 4.0 or below. Windows 3.0 in real mode may eventually work as well.
