Yop, and permament registration:
Minimal patch (only two bytes) for changing two “je” instructions to “jne” instructions:
echo -ne "\x75" | dd of=NoREpls1.1_patch.exe bs=1 seek=2490 count=1 conv=notrunc
echo -ne "\x75" | dd of=NoREpls1.1_patch.exe bs=1 seek=1776 count=1 conv=notrunc
This removes the “demo version” string from about dialog and also makes available the save functionality. But register functionality and demo string in the windows title still remains, but this is IMHO good cost-benefit patch and full functionality will survive program restart.
