Tower of Sokaban by Killer Bean 2 and BG is a small demo of what will hopefully, one day, become a somewhat playable game. The gameplay is, as you could guess from the name, about moving blocks around.

You’re Derpy Hooves, mail mare. Spike’s ill, so Twilight Sparkle has asked you to fly her letters to Princess Celestia. But Gilda is harassing you! Fly around and press button two to drop an anvil on her. It’ll make her much more angry, which is probably not all that good of a plan, to be honest. Avoid getting hit by Gilda – she’ll steal one of Twilight Sparkle’s letters. If you lose all three, you have to return to Ponyville.

This is a very basic game with no real ending – it just gets harder and harder until you lose all you lives or it loops around and goes back to the starting difficulty.

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:

+ Proper save requester, including support for basic file management operations.
+ Alternate between two different directories by tapping the save/load file icon again.
+ Quickly switch models in load requester with various L/R+X combinations.
+ Risky operations now use confirmation requesters.
+ It is now possible to step the emulation frame by frame.
+ Added pouet.net and Tipshop pokes library to servers.cfg.
* Implemented HTTP redirects, required by some pouet.net sites.
+ Directly poke decimal, hexadecimal, or binary values in the data dump view.
* Switched to PNG for background and icon graphics. The BMP support remains, but note that some names have changed – check skins/readme.txt for details.
* Augmented the 128k keyboard graphics with symbol characters. Thanks, Paddy.
* The selected keyboard is now saved to the config file.
* Distinguish the load and save slot screens with colored slot frames.
* Disable the keyboard matrix effect during multiplayer session. It is often difficult enough to configure the controls even without it.
* Switching to maximum speed while loading tapes in fast mode now disables the display updates entirely. Handy for slight speed boost if you feel desperate.
* Other subtle changes (nicer boot message, increased cheat poke limit).
* Fixed loading of Pentagon SZX files (ROM paging, step direction).
* Minor bugfixes (libfat mkdir and aliasing, ZIP long name skipping).
