These are quite mindless, but they are rather useful on simple examples
in which we don't care about performance and we just want to show
something on the screen.
For now this didn't matter much, but on real hardware I was able to
reproduce the same glitches as with emulators which randomized memory on
both the CPU memory and on the PPU. Hence, just allow some examples to
manually reset these regions and avoid silly graphical glitches.
