Gp2xpectrum 1.5b2


Metalbrain

Still Fresh
Hi all!

Even though screen emulation ain't 100% perfect yet, I promised a fix for F200 users this weekend, and right now it's already better than the last version, so here it is:

http://www.speccy.org/metalbrain/GP2Xpectrum1.5b2.zip

What's new:
- Small timing fixes.
- Screen rendering code has been totally rewritten from scratch, and now border is completely
emulated (Sentinel letters can be seen), and visual effects of many demos are finally perfect
(Overscan, Shock and similar). Some demos (such as MDA) are still failing though.
- On F200 model, battery level ain't polled, avoiding the resulting massive slowdown on
that model.

Beware: I don't have a F200 model, so the fix for F200 haven't been tested, but I think it should work.
 
overscan doesn't work
and SHOCK looks better in 1.4 ..at least for me
2.1 firmware / F100

tried pera putnik's BBG border bar generator
works great in 1.4 and great in 1.5b2
here are a few images just to see what i am talking about
anyway nice to see this project focuses on 100% accuracy
thankyou Metalbrain

This new release is the fastest one and with the sound at 44khz :)

Almost perfect Spectrum emulation at 175 mhz contention ON or less :)

Thanks Metalbrain ;)
