Need help with hex files

I currently have no way to compile a hex file and I am asking for help from anyone who can make a hex file. I need 2 forms of Toykeepers Crescendo firmware, one build I need for the triple channel Texas Avenger non ldo board. The second hex file I need is for the A17 L81 driver with the trace cut. So when the 2nd channel kicks in the first channel shuts off.

Mcu is ATTY25, goodnight is one special mode I’d like to have in the fw, and batt check. Other than that I’m not to picky about the rest. Thank you In advance
