"Bare Metal" - does this mean the RPi can run blob-free?
A possible improvement I suggest is to gfx_draw_line in gfx.s - using a fixed-point algorithm could be simpler and faster: http://hbfs.wordpress.com/2009/07/28/faster-than-bresenhams-...
Even though the game does not need an operating system, it still requires bootcode.bin and start.elf.
The fixed point version of Bresenham's algorithm looks really nice on x86, but it uses integer division, so implementing it on an ARMv6 (no div instruction) would be quite painful.
Consider participating in the demoscene, this is the sort of skills that would be great for that.
Place floppy on drive, press Ctrl+Amiga+Amiga and up you go.
Congratulations.
There is a bare metal chess game [0] for the Pi that was presumably another teams entry for the same assignment (they are both from Imperial).
When I was 16, I enjoyed using higher level languages but the real fun was doing Assembly.
Kids these days real need to get some of this exploratory desire back.
Good show, I've often felt low level was a dying art, perhaps I'm wrong and stuff like this will push people to learn what a register is and what "flags" are.. :-)
The main issue is of course portability, but I had lots of fun with Assembly during that timeframe.
Do you know how RISC OS fares in the Raspberry PI?

You can also download RiscPC or Archimedes emulators, e.g.
And here I am sitting here, with little x86 asm and z80 asm knowledge, reversing windows binaries and messing with Pokémon arbitrary code execution exploits. (optimizing my payloads for the 8F/"ws m" exploit is fun though!)
Been meaning to learn ARM asm for some time, but haven't got around to it.

I've got as far as installing the SDL headers (you're looking for SDL.h from SDL 1.2) and running cmake . but not much further.
I have added a more informative README and fixed a couple of issues that prevented the game from running. In case you need any more help, could we move this discussion to GitHub issues?
Mainly I was waiting to reboot into Linux to try to build this.
You may want to add some instructions for building the game/emulator.
For the emulator, I'd never used cmake before (sort of) so I didn't know to run cmake .
Then the error about SDL (needed libsdl-dev package or similar)
For the game, I'm currently downloading a Linaro ARM toolchain on a slow connection but I don't anticipate any further issues.
Nice work - love it (might play it at some point to see if I'm any good).
My day job, on the other hand is nearly all web dev and admin work.
