DSx86 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.

Changes:

New EGA 640x350x16 and VGA 640x480x16 graphics modes.
The NDS shoulder buttons scroll the zoomed screen left/right (as before) when not already at the edge, and up/down after that.
Fixed Master of Orion SB digital audio problems.
Changed EGA text output to use INT43 vector (fixes text problems in Space Quest I, etc).
Fixed EGA Read Mode 1 handling (DOUBOLO).
Improved EGA palette handling (ZOOL).
Fixed WC2 savegame handling, which was broken by the DUNE2 savegame handling fix. They call the same DOS function, but expect it to behave differently. Argh!
Added support for INT03 (see previous blog post) and INTO (overflow interrupt).
Implemented Mode-X VGA offset handling (Alien Breed, Traffic Department 2192).
Implemented diskette motor counter handling to INT8 (should fix Civilization hang problem).
Added about a dozen new EGA graphics opcodes.
Added about a dozen new Mode-X graphics opcodes.
Added support for several new DOS and Mouse interrupts.
Added support for several new I/O ports.
Added most of the previously missing characters to the 6×8 text mode font.
Attempt to avoid writing duplicate entries to the debug log.
Ignore SB Direct DAC output for now, pending proper implementation.

Learn Japanese is a trivia game designed to help people memorize Japanese words.

Release notes:

Konnichiwa! This is my most comprehensive version yet, pretty much all the core features I wanted are fully functional. There’s now a total of 6 stages, but in order to access the 6th stage you must complete stages 1 – 5. As usual I added more audio and images. I also included a nifty video intro featuring Kirsten Dunst in the PSP XMB menu, check it out.
