Patched version 14 boot ROM – Provided by labomb:
The one thing that was missing was a single ROM that would not only support loading the standard software “cycles” from NABU Network’s Internet Adapter software or server of your choice, but also new applications such as CP/M, homebrew applications, and that additionally offered the ability to boot the CP/M operating system locally from floppy disks or disk images (for example on a Gotek or similar device).

NABU Keyboard ROM With Updated Paddle Support:
Paddle support already exists in the stock NABU keyboard ROM, however this fixes a bug that causes issues when using the second paddle on each controller port. It’s possible to get the second paddle into a state where moving the controller port’s first paddle causes the second paddle to move as well basically tracking the position of the first paddle. Thanks to NABU MAME developer brijohn for this updated ROM.
