Description	*Updated 20/09/08* - James Smith and Dr BEEP have further improved Andrew's program, leading to this version finally posted by Dr BEEP. It assembles to a mere 12 bytes - that's an average of 4 bytes each for Andrew, DR BEEP and James Smith. Following on from the above entry, we now have the Power Users version of 16K Spectrum Emulator written in 100% pure assembly language. It's probably about a million times faster than the previous version, so that's a nice speed improvement. You can either download this entry as usual or copy'n'paste from here:- ; Advanced 16K Spectrum Emulator ; Copyright 2008 Andrew Owen, Dr BEEP & James Smith org $nnFD dump $nnFD start equ loop+2 loop jp p,$11cb defb 0,0 ; Initially LD DE,0 then just 2x NOP di ld a,c ld (de),a dec de and d jr loop At 21 12 bytes when assembled, you may be interested to know that this is so far the shortest entry submitted to CSSCGC 2008.
Comments	This little known deep underground coding triumvirate (a.ka. Tres Hombres) have done it again, sneaking this 12-byter out onto an unsuspecting compo spectatorship. In fact, if you can excuse the difficulty I was faced with on writing an entire paragraph on a twelve byte piece of code, I don't really have anything additional to say about this one apart from it does exactly what the BASIC version does, is about a million times faster at filling high-memory and has been expertly byte crunched by our optimising friends. The machine code trick used is one for the books though - use the source, Luke. It is a little known fact, but the ultimate 2008 crap game experience can be had by using this program to step through all of the 16K games in the compo and find out which ones work under it yet had missing UDGs in 48K mode (not that I ever did this).
