I'm currently trying to get the OD hac by dimented to assemble, and am eccountering the exact same problems as junkcltr (see post 325 and 327 of tbi guys its time to update) with the program being offset and extended adresses being coded as direct adress. Ive run the file through the mini ide under windows and under dos as suggested by dimented but am getting the same results. Dimented has suggested adding a constant byte to correct the problem. I'm not sure what is meant by a constant byte, or how it is to be used, should it be placed in the .asm file or formatted into the mini ide. definatly would apprreciat the help. thanks

Is it just a few of the addresses being different? I remember fixing a few errors in the original code that used the incorrect addressing modes where used in several places.

Actually their are quite a few differences, I found four corrections you made at C322, C338, C754, and C77D where you switched from extended to direct addressing. This was offsetting the bin by a total of 4 lines (or maby bytes) which is what i was seeing when comparing bins in tuner pro. Your refference to the constant byte was throwing me off, thought i was making a mistake when converting it to a bin. Turns out my mistake was not re calcing the check sum which changed due to your corrections. I have fixed the checksum and now have the reassembled bin working . Thanks for your help dimented
