I think it's prudent to avoid the use of hack software written by people like me
If it's any assurance, this is as old as GPSMAP66 device firmware 2.10 (2018), and no problems yet.
I'm still hesitant to support a device that I can't test first hand (GPSMAP 66i for example).
Version 10 is almost completed:
- Restored support for all older device firmware versions back to version 2.10.
- Restored and tested the firmware version spoofer functionality with version 10.20.
- Small code and appearance fixes to program and interface.
- Added support for device firmware file naming, as downloaded from GPSrChive.com:
"GPSMAP 66 B3028 10xx.gcd" so no longer need to rename downloaded firmware files.
I'll just put it here when ready.
