Subject: Remove unused "dual monitor" code; clock CPU faster
X-Git-Tag: rgb2rv17~15^2~2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=7df0f672c23cd63e026cab7765075d6fd652a34a;p=c128-kasse

Remove unused "dual monitor" code; clock CPU faster

We never used the C64/VIC-II monitor at events because we didn't have the space.
A nice side effect is we only need to call fast() once to double the CPU
frequency, which should speed up numeric computations.
