Thanks for the amazing job on porting doom rp2040 to Thumby!

I had a blackscreen issue too, thanks for the fix above regarding lowering SPI clock, now it works.
Although there is still a problem with syncronization (not that stable like other greyscale thumby games) .
Also greytest.py doesn't work for me (I think because of the same SPI issue)

1. I have wondered is there a way to match thumbyGrayscale.py text params to the one in i_video.c?
My params which work fine for me: gsV3,timing,110,oled,1.
2. Is it a good idea to find more precise SPI clock setting? Now I am using 6000000

In attachment some compiled binaries for people with the same problem
