re: Atmega asm (not a fix!!)

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

TBH m8 this is the newbie forum and although theres a few people here who know about boxes and are just here helping people to get post count up to access and post on the big boy forums.

So i doubt you'll get much of an answer in here unless CG stops by or one of the more talented cable guys.

Cheers
