ZX Spectrum emulator
pabouk:
The speeds of Manic Miner with grayscale lib are:
frameskip speed %
0 32
5 57
fast 67
So with the most usable frameskip 5 there was 15 percentage points increase.
Unfortunately I do not think that the speed gain is worth the sacrifice of the number of shades. For example the second screen in Manic Miner is unplayable becase the platforms have the same colour as the background with 4 bpp :(
If you want to include the 4 bpp driver I am strongly for leaving the grayscale lib there too and adding an option "full grayscale" / "4 bpp".
theli:
switching different rendering driver from options is not what i wanted to do...
so i'll leave grayscale rendering for now.
pabouk:
Great ;D !!!
I have 99% speed with frameskip 3 and grayscale lib on H120 now :D
It seems that the better IRAM usage improved the speed greatly.
Speed in fast mode is between 160 and 190%
Thank you for your work, Theli.
Is the sound supposed to work correctly now? It seems to be non-continuous and sometimes I hear a loud pop.
theli:
sound support still unfinished ...
it only should not crash rockbox for now. ;)
by the way, as speed calculation is not very precise 98-100 % usually means 100% :)
chibacity:
Great work theli!
I'm running the emulator on a H300 and getting 100% on 2/3 frameskip, and sometimes 100% with no frameskip. Great stuff.
Just a couple of questions...
Has anyone noticed that the virtual keyboard works a bit sporadically? Or is it just me... Some key "stokes" seem to be getting gobbled up.
A game that I tried to play (Uridium) requires a key that I can't seem to map SYM/SHIFT?
Has anyone got Uridium to play with joystick mode. I can select single player joystick mode (3), but I cannot get the game to start.
Cheers.
