I finally got this DIY Flipper Zero clone working but it needs more work! I had to buy the processor and LCD as they are not common ones.
Here is my schematic so far. I simplifed the wiring but the keyboard and SD card are having issues so it might not be correct!
Here is a picture of the wiring. The IR and RF modules are not yet connectd.
Its up and running (barely). I can not get the SD card working properly.
First life, its ALIVE finally thanks to ARTFOR for the instruction videos.

After fighting with the keyboard forever, sometimes I had to press a button 5 or more times to get a response, I switched to an older FCFZ design that does not have a 75HC165. But this version had the same problem! Then I updated the flipper version from 1.4.1 to 1.4.3 and the issue went away!
Here is the new, simpler schematic with a working CC1101:
