hi adding my thoughts to wot tonmedia11 has done, would the code go something like this.
DOKEYROLL7:
LDI YH, high(M) ;Set Y pointer to start of decrypted EMM in
RAM
LDI YL, low(M)
LDD R16,Y+A ;load with value at 87 which is $B7
LDD R17,Y+R16 ;load with value at B7 which is $FF
LDI R18,0x10 ;load with 10h
EOR R18,R17 ;eor $10 with $FF
STS Y+R16,R18 ;store value of the eor at $B7
this is only for first part of emm,not to sure about if the instructions are correct.just showing wot im trying
to do.has anyone got the source code cause i have lost mine,and also has anyone got any info wot the registers are.
thx
