Micro64 ist ein zyklusgenauer C64-Emulator von Benjamin »BeRo« Rosseaux (der auch u.a. den Emulator brotkaestchen und Hyper64 geschrieben hat und Teil des farbrausch Teams ist). Es gibt Binaries für Win32, Linux-x86, Linux-x64 und neu auch für 64-bit Mac OS X. Wichtig: mit der F9-Taste kommt man in das Menü

Version: 1.00.2012.06.26 Build 694 SVN revision: 2311
Date: 26. June 2012 Time: 15:36 UTC
--------------------------------------------------------------------------------
- Optimized VIC NMOS glitch GLSL shader pass in the new PAL full emulation,
removed branches and replaced it with branch-less max/step/sign function
chains, and reduced texture lookups from 9 to 5 down per output pixel for
some weaker but still good midrange or highend graphics cards, because when
Y/luminance is going from high to low, the transition is relativly fast
(about 0.5 VIC pixels), and when Y/luminance is going from low to high, the
transition is relativly slow (about 2 VIC pixels), and because the PAL
emulator works in 768 texture pixel width resolution instead 384, so all
widths are 2x width, 0.5*2=1 texel and 2*2=4 texels, so more than 5 texel
(4 + 1 for the initial Y state for the VIC NMOS glitch emulation algorithm)
texture lookups are not necessary here.
- Replaced the blackman-exact window with an dolph-chebyshev window of the
three (YUV) 17-tap windowed SINC FIR lowpass filters in the PAL signal
bandwidth filter GLSL shader pass for to fix some small optical issues.
- Reduced multiplication operations to the half in the PAL signal bandwidth
filter GLSL shader pass, since the SINC lowpass filter kernel coefficient
values in the PAL emulator in micro64 are symmetrical, so one vec3 filter
coefficients multiplication per two texture lookups (one per each half
direction) now instead two vec3 filter coefficients multiplications per
each texture lookup.
- Removed a waste additional plain-from-FBO-texture-A-to-FBO-texture-B-copy
shader pass. It was only for debugging usages but I´ve forgot to remove it
in the release builds.
