Really? CPr_b: function() {
var i = Z80._r.a; // Temp copy of A
i -= Z80._r.b; // Subtract B
Z80._r.f |= 0x40; // Set subtraction flag
if(!(i & 255)) Z80._r.f |= 0x80; // Check for zero
if(i < 0) Z80._r.f |= 0x10; // Check for underflow
Z80._r.m = 1; Z80._r.t = 4; // 1 M-time taken
}
Who anybody other than a machine will be able to make sense of that? |
