Subject: Remove superfluous bytes in program disassembly
X-Git-Tag: v2.0.0~58
X-Git-Url: http://gitweb.hugovil.com/?a=commitdiff_plain;ds=sidebyside;h=359b0be02becb952016f0f79f6e608c7737378e7;p=emu8051.git

Remove superfluous bytes in program disassembly

Sometimes, B1 and B2 were showing old values from previous disassembly.
Now explicitly remove them for each disassembly line.
