'SPECTRUM IS ALIVE!' page updated!
New version DSP 0.3WIPß4
• General:
+ NEW: Icons changed...
+ BUG: Fixes here and there to get more stable DSP.
• Spectrum:
+ BUG: Fixed stupid bug in 128K screen, now 'La Abadia del Crimen' works and many games that uses additional screen works too (Loading screen in 'Avenger' and 'Death Wish 3').
+ BUG: Kempston joystick bug fixed, now in 'Silent Shadow' works Kempston joystick.

+ BUG: Bug fixed in sound chip, now music in 'Deatwish 3' don't stop.
+ BUG: Rewrite from scratch tape system:
- If you load a tape (TAP or TZX) and press 'LOAD ""' it sets 'play' and maximum speed by default.
- Fixed the way 'Loop's' where show.
- Now if there are more tha 255 elements, you can chage tape possition (Dinamic and BleepLoad loaders)
- Rewrited (again) TZX conversion system and TZX next bloq, many loaders now load and don't fail ramdom
- Now if you change from TAP to TZX and it's loading, tape possition changes OK.
Look at downloads section.
Now some amazing case, I have tested many TZX tapes and I found two of them that don't load: 'Basil the Great Mouse Detective' and 'Mask'.
My first reaction was use RealSpec and 'surprise!', they don't load too... I use EmuZWin the same results... very extrange.
Looking at tape loader (was the same for both games) I make some modifications in the TZX (I changed header long, if it is even don't load and if it is odd they do) and finaly they load.
In my emulator both load, but in RealSpec, they don't. And in EmuZwin 'BGMD' loads and 'Mask' don't.
Later I test in VBSpec and 'big surprise!' both of them load! (the basic of load system I leardned from here).
This two tapes are in my Spectrum dedicated section in this web (Look in Gremlin Section)

Wow!
Five months have passed since my last update!! The DSP proyect isn't dead, but many things happened in those five months. 
Most interesting thing is that I have a new vesion of DSP ready, with very big changes inside. Changes affect video
and funtionality. Now everything on the same window, no pop-up graphics window.
Now I can syncronize audio with emulator also, because the new implementation.
Now loading tapes it's more easy than before, and if you don't use tape, you don't see it!
Only two small questions ramains, first I must optimize my code (a bit inestable now  ) because the big changes in graphics functions, and
second, by now I don't have a computer (my brother Benja is doing his best ).
Maybe in a week I solve those problems and a new version of DSP can see the light.
Thank you!
PD: I'm looking for one icon to my program and some people who want to contribute in DSP (you don't need programming skill, you only want to have fun programming!)
