TIM/TUBE make: *** No rule to make target 'timer.c', needed by 'electron-rom-emulator.elf'. Stop.

Hello, I am getting this error when attempting to compile the TIM/TUBE branch.
make: *** No rule to make target 'timer.c', needed by 'electron-rom-emulator.elf'. Stop.

I have previously built the master branch succesfully, using the same set up you have,
STM_COMMON=../STM32F4-Discovery_FW_V1.1.0 and
CC=arm-none-eabi-gcc

and I did a make clean before trying make.

Can you help in any way?

I found the files timer.c and timer.h in https://github.com/kernelcrash/dragon-rom-and-floppy-emulator. It compiles fine, and making the neccessary extra connections it works. First minor issue is that it won't auto run on a shift-break from disc 1, just errors 'no disc'. Disc 0 works fine.
