Hi Eric, > $29E = %0001010011110 since A7 ($080) is high, it's a RIOT address. Since > A9 ($200) is high, it's a RIOT register address. RIOT register $1E is > (according to > http://www.6502.org/documents/datasheets/mos/mos_6532_riot.pdf) the same > as > TIM8T except it enables the interrupt from timer to !IRQ. Wow, thanks. So what are your theories on why this was done? Maybe to confuse us that reverse-engineer their code :-) Take care, Dennis
