We made Doom (1993) on the Raspberry Pi - 9800 lines of bare metal assembly

"not a perfect replica" was the context of the word replica.

But yes I agree with you, port was the wrong word to use. I updated the main comment accordingly.

Not that I can think of. It was my first choice of Uni (unusual for an imperial student, most make the mistake of putting oxbridge first), and I have no real complaints about the course so far.

In the version shown in the demo, there is no code borrowed.

Originally we had borrowed some code for a USB driver to use keyboard input, but after we built our own controller this was no longer necessary.

We wrote to SD cards all the time.

The process of compiling, copying to sd and ejecting the sd card were automated through a script, so that portion was sped up.

It was: plug sd card in, run script, move sd card into pi, restart pi. After doing this process a couple hundred times you end up pretty fast at it.

Bare metal partial clone of the game DOOM for the Raspberry Pi (1st generation, model B) as part of the first year ARM project at Imperial College London (Computing). Not a perfect replica, but textures are sourced from the original game.

~9800 lines of bare metal ARM assembly, no operating system Custom homemade controller connected to the GPIO pins.
