the ZX Spectrum emulator
Why build an emulator ?
The obvious reason is to emulate...
Our reason of why we built this emulator is pretty much twofold...
Firstly: the nostalgia we all remember the classic ZX Spectrum (if not your going to love it, now that's a guarantee !) warts-n-all the Spectrum was for many very entertaining and for many the first home computer - being homebred here in the UK it was hugely successful, Clive Sinclair was a British hero, rightly so.
The games where amazing (in the 80's - remember) and although the graphics were less colourful than its closest competitors namely the C64 (which allowed more than 2 colours to be displayed in a 8x8 pixel square) it didn't stop it from being very popular...
Secondly: and completely off subject we wanted to learn the latest Microsoft .net frame work and accompanying languages and in order to see what it could do we needed a project...
Viola... here we are
ZX Spectrum emulator for .net (you get it yet, hmm sad huh...)
What can it do
Emulate all the original Sinclair Spectrum models16k, 48k, 128k, +2, and +3 (including floppy disk drive), Screen (wouldn't be much good without it) inc. correct timing and borders -( Vectron, Arkanoid, The Sentinel ), Sound, Memory delays, load tape files and snap shot files inc. tzx tap z80 sna wav - original analogue tape via external cassette deck and sound card, or even mp3 player, plus Joystick interfaces Kempston, Sinclair. Its pretty much a complete ZX Spectrum.
For more up to date info check the History column on this page or just download the emulator and see for yourself.
We've played lots of games, loaded programs, written machine code and basic ... removed bugs, all is well, but there are so many programs (countless over10,000s known tapes) all with possibilities for error so without spending months on testing we wont find them all..
that's where you feed back any bugs you may have found.
What can't it do
Run Commodore 64 games!?, But then who in their right mind wants too ..? (ouch)
OK so we don't have the room on the net to answer this one...
We are still adding functionality and other spectrum related software projects... work, work, work...

Loading a Game or Program
The simple Way
Although you can still follow the path below there's a much quicker way to load games, drag and drop your games on to the TV screen and the emulator will do the rest!!!
The traditional method
To get started first press button at F on the TV screen and the tape deck window will appear.
On here press the button at U and the browse window will open to allow you to select your tape or snapshot file you want to open.
If you select a .tzx or .tap file go to the TV Screen and type: Load "" ( to do this on your keyboard first press the keys j then holding down CTRL press p twice, now press Enter) and the inserted tape will now begin to play.
GAMES!
We've now included a couple of games in different formats to help those non technical get started.

Want more info ? Information
we need your help!
ZX Spectrum Cassette Database
In order to maximise the database we need to find as many cassettes as possible, from unknown ones to ones known but we are unable to locate.
If you can help us with any old cassettes you may have in the loft you no longer want or know someone that has then please contact us and give them to a good home, If we can't get there in person we can get them collected by courier - please don't throw them!
Don't worry if you have no old cassettes please register your copy of the emulator by doing so helps us obtain further hardware and software for the project, and plus gives you full functionality of the emulator.
