OK, using the configs from Gabe’s repo and also the latest code from ToyKeeper’s I’ve compiled up the HEXs.
I had never compiled for attiny 1616 before so had to get that configured. Also hit a compile error, looks like there’s a typo in the “hwdef-Sofirn_SP10-Pro.h” file (“FUSE_ACTIVE0_bm” should be “FUSE_ACTIVE_0_bm”). Probably a change in the attiny pack. Anyway, not important.
Please note, I don’t have an SP10 Pro or TS10 so this was untested. However, I only had to uncomment 3 lines in 3 separate files to remove the auto reverse direction reset from the ramp, candle, and lightning modes.
Also, you should now have the new tactical mode: 6C from off

Another option instead of disabling the auto reverse reset is to change the default timeout from 2/3sec to something much higher, like 1 minute (if you prefer). After a minute I’d likely forget which direction I last ramped
