This is just a small program for setting the MAC address of an RR-Net. Someone requested a prog like this, and I sort of already did it, so I thought I might aswell share it.
The program first displays the MAC address currently stored in your RR-Net. Then it writes a new MAC address to your RR-Net and finally it reads back the newly written MAC address and displays it.
The MAC address written to the RR-Net is 00:80:10:00:01:40
This address is located in the binary at the very end. So to set your own MAC, just modify the last 6 bytes of setmac.prg to your liking.
It has support for RR-Net on MMC64 or Retro Replay. If you have RR-Net on both it will detect the one on the MMC64.
It can be launched from MMC64 BIOS.
I have not yet tested if it can be launced from TNT's Browser. In fact, I have not yet tested it on real hardware

..but the code is 99% like ShowMAC and it seems to work in Vice, so I guess it's ok
