Mr.Smith
Thanks a lot! But your patch has one side effect. Under DosBox emulator graphics rendering have interlacing after your patch applied. So, IMHO, it is better not to fix rendering at all.
Moreover, I think not everyone can apply this patch easily. I prefer to play this type of games under DOSBOX emulator. Based on your patch I made simple one, which removes just copy protection and leave all other parts of game:

ROBOT ODYSSEY copy protection fix.
