Hi,

I further investigated in the no keyboard, no mouse problem
on Raspberry Pi.

When compiling SDL2 (I used version 2.0.3 [1]) on Raspberry Pi,
please make sure (as explained in SDL2's README-rasperrypi.txt)
that you

1) meet the Build Dependencies for SDL2 on Raspberry Pi:

		sudo apt-get install libudev-dev libasound2-dev libdbus-1-dev

2) the pi user (or the user you intend to run SDL2 apps with) is member 
	of the input group

		sudo usermod -aG input `whoami`

	It seems like logging out and logging in is required for the group 
	membership to become active. At least it was for me.

Only then start building SLD2 (in SDL2's directory):

		./configure; make; sudo make install

Running oberon-risc-emu should have working mouse and keyboard then.

On one system I tried to use SLD2 without meeting the Build 
Dependencies ( 1) above): SDL2 compiles fine but keyboard and mouse
will not work with oberon-risc-emu. Only establishing 1), removing the 
SDL2 directory, re-unpacking SDL2 and compiling from scratch helped. 
A mere rerun of configure; make; sudo make install did not succeed.

Let us know if this works for you.

Regards,
