Firmware for the Casper TW9 built on Quanta board DA0QL4MB8D0, revision D, stored in a 1.18 MB 7z archive. A separate revision E dump of the same QL4 platform exists, so read the code printed on your PCB carefully before choosing. Quanta numbering places the project code after DA0 and the revision in the trailing characters. Flash via an SPI programmer, keep a backup of the existing chip to preserve unique data, and check the file size against the flash capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfiles. Enginerys does not host this file.
