ZXDS is an emulator of Sinclair ZX Spectrum for Nintendo DS, written by Patrik Rak. It is steadily reaching a mature stage of development, and it already has some noteworthy features, like accurate emulation of Spectrum 48k, 128k and Pentagon models (including sound), or support for TAP/TZX/PZX tape files, TRD/SCL disk files and RZX playback files.

Changes:

ZXDS 1.3.0 (1.7.2014)

+ ULA+ emulation for all Sinclair and Amstrad models.
+ Support for all types of 3.5″ double sided +3DOS disks.
+ Raw screenshots now support the ULA+ extension for both saving and loading.
+ Current ULA+ palette can be changed simply by loading the appropriate ULA+ palette tape files.
+ Other ULA+ related changes (BMP screenshots, thumbnails, SZX support).
+ The selected ULA mode as well as the display mode are now part of the config file.
+ You can now keep your desired custom configuration persistent separately in custom.cfg.
* Sector viewer now displays bottom side track addressing info in inverse colors.
* Reverted special treatment of full size TR-DOS disks, so padded images work again.
* Minor +3DOS fixes (gap3 reading, EDSK track padding, SZX disk side selection, motor bit disabling)
* Loading a POK file now automatically shows the poke screen. Pressing Y switches back, as usual.
* Reading attributes from unmapped ports on Pentagon now mimics the real hardware mod behavior.
* Other subtle emulation accuracy improvements (+2A/+3/Pentagon screen timing, 128K/+2 INT duration).
* Many internal changes (optimized screen sampling, optimized contention, async palette switching).
* Other subtle changes (UNDO media keeping, CPU stepping prior snapshot save, volume mode order).
* Minor bugfixes (media slot release, paths set to root dir, filter in root dir, allowed filter chars).

EgoTrip updated his game Jewel Warehouse. Its a puzzle/platform game where the idea is to collect all the jewels on each screen then head to the exit. There are various obstacles such as spikes, fires, acid drops, and puzzles to be solved such as pushing crates to make a path, and conveyor belts.

Changes:

Fixes:
* Changed timers on acid, they drop at a challenging speed again.
* Changed speed of water
* Fixed Level 24 ladder bug

lolSnes is a project Mega-Mario started two years ago. He wanted to make a SNES emulator for the DS, that could render most sane games without glitches. So far, Super Mario World is playable, to some extent.

What is currently supported:

* CPU — 99% (all opcodes emulated; may miss a few unimportant bits about timing)
* PPU — ~40% (mode 1 BGs, OBJs, mosaic, master brightness, giant kludge for BG3 prio)
* SPC700 — 80% (most useful opcodes implemented, CPU/SPC I/O, timers)
* DSP — 0% (yep, no sound)
* SRAM with auto-saving

grape is an Open Source Apple II emulator for Nintendo DS, powered by devkitPRO, libnds and lots of LemonBoy sweat.

grape – Apple II emulator for Nintendo DS

Consider it as a WIP, it lacks some stuff like configurable keymaps and extensive testing. The video generation takes ~50% of the CPU time and would definitely benefit from optimization, beside the fact that it doesn’t emulate color bleeding. When playing games that make extensive use of disk IO disable vblank to make it load faster (eg. Karateka and Pacman).
