feature request: ZX Spectrum support

[GoogleCodeExporter]

This is a great emulator but it doesn't actually support any of the official 
machines. This means any software that require specific timings (for example 
Bozxle) doesn't run correctly. This means us poor Symbian users can't run these 
titles on our phones.

What steps will reproduce the problem?
1. Load Bozxle in 48K mode. 
http://www.worldofspectrum.org/infoseekid.cgi?id=0027065

What is the expected output? What do you see instead?
8x1 attributes in the play area. 8x8 attributes in the play area.

What version of the product are you using? On what operating system?
Current version on Symbian (Nokia 700)

Additional information:
Perfect emulation of UK machines is not required, only accurate contention 
emulation in video RAM and correct number of t-states before start of screen 
draw.

Hi!)

I thought about this, but memory contention must be added into the emulator 
core (z80, ram, etc).
The core has been developed over 10 years by many developers and preciselly 
tuned to russian clone Pentagon (that became standard for demo scene and 
multicolors).
I dont want to break it with my changes ;)

This project created to port this excellent emulator to many platforms.
Also afaik there is many contention differences between orinigal speccy models 
(read this page for more details 
http://scratchpad.wikia.com/wiki/Contended_memory).
