DS81 - Sinclair ZX81 Emulator for the Nintendo DS

[wraggster]

Noddybox has released a new Sinclair ZX81 for the Nintendo DS, heres the release information from the site:

If you'd have told me 25 years ago that I'd be playing 3D Monster Maze on the bus on a device powered by batteries, I'd have said you were mad...

DS81 is a basic emulation of the Sinclair ZX81. It currently doesn't support loading of external files, but includes a few games to try out. Note that I did not write these games, or own the copyright to them. They are included in good faith (as far as I know the authors do not mind this work being distributed), and if any of them want their work removing I'll gladly oblige:

ZX81 ROM © 1981 Nine Tiles Networks Ltd
City Patrol © 1982 Don Priestley
Sabotage © 1982 Don Priestley
3D Monster Maze © 1983 Malcom E. Evans

When you run DS81, following a splash screen, you'll be presented with a ZX81 display on the top screen and a soft keyboard on which you can type. If you click on the bottom part of the touch screen you'll be presented with a menu where you can choose a tape, reset the ZX81 and set the sticky state of the shift key on or off.

Once you have selected a tape, simply type LOAD "" on the ZX81 to load it! All the included games map the joypad and buttons to sensible settings for each specific game.

This is great stuff!
The ZX81 was my first "computer". I had the 16kb memory expansion pack and thermal printer that printed on 4" wide paper. It taught me Basic programming and got me started in the computer industry.
This brings back a lot of fond memories.
Thanks very much to the author!!

I can't wait for external file support so I can play the Lunar Lander game which I wasted MANY hours on.

If you're using a 2GB SD card for this homebrew on your DS, it contains more memory than all the ZX81s ever sold combined.
RAMPacks not included of course...

Evening all

A new version of DS81 has been released which allows the loading of external tape files.

Well, at least it should!

I've been able to test it in Dualis but my device isn't supported by whatever FAT routines are in libnds yet.

Have fun.

Well, that'll teach me to try and squeeze a release out with minimal testing...

There's a new version, 1.1a, that has fixed the keyboard I destroyed in the last release, available from the usual place.
