#1 Problem in m6502.c with ADC

[Jim Reneau]

In Decimal mode SED addition not carying from low order nibble correctly to high order nibble
The following code
SED
LDA #0x09
ADC #0x01
is currently setting A ro 0 not 0x10 as it should.

in m6502.c in the ADC function change
tmp = (Op1 & 0xF0) + (Op2 & 0xF0) + (tmp & 0xF0);
to
tmp = (Op1 & 0xF0) + (Op2 & 0xF0) + (accumulator & 0xF0);

Please review and see if you agree.
Thanks
Jim
