Creating a DCPU-16 emulator in C++11

In this tool-assisted education video I create a DCPU-16 emulator with C++11. You see me type every line. I also create an assembler for the DCPU-16 with macro support. The program is sort-of portable; it compiles on any architecture that support libSDL, Twitter:   / realbisqwit   Patreon:   / bisqwit   (alternatives at https://iki.fi/bisqwit/donate.html) Twitch:   / realbisqwit   Homepage: https://iki.fi/bisqwit/ I believe a DCPU-16 emulator is a good beginners' challenge for emulation, due to its simplicity. It doesn't take much time to implement the 1.1 version of the emulator, and the 1.7 version is not that much more complex. This video also showcases all the documentation from which it draws. (Except the C++ standard of course.) The emulator is written in several phases. Phase 1 (0:00 - 7:22) 290 lines -- DCPU-16 version 1.1 emulator with graphics support. Phase 2 (8:33 - 18:02) 681 lines -- Added text mode support and an assembler. Phase 3 (18:27 - 25:53) 848 lines -- DCPU-16 version 1.7 upgrade! Also added extra assembler features such as macros. Phase 4 (26:10 - 32:43) 944 lines. -- Properly implemented the DCPU-16 version 1.7 hardware interface. The outcome from each phase is demonstrated separately. Demo 1 (7:22 - 8:33): Pacman clone. Demo 2 (18:02 - 18:27): Rendering demo. Demo 3 (25:53 - 26:10): Revisiting Pacman shortly, showing that despite quite different machine code, it still runs as long as the assembler language is backward compatible and the I/O hardware is the same. Demo 4 (32:43 - 35:21): DCPU16-CBMBASIC and AtlasOS. You can download all the source code at: https://bisqwit.iki.fi/jutut/kuvat/pr... Documentation and resources: http://dcpu.com/ https://github.com/gatesphere/demi-16... The video includes English-language narration by me. I hope it is not too distracting! I am sorry that sometimes my voice clips (http://en.wikipedia.org/wiki/Clipping... ); it sounded fine with my cheap headphones when I was recording it, despite looking ugly in the waveform editor... But luckily those parts where it does clip are few. It also includes background music. Background music: Zelda Wind Waker ocean theme, composited from two MIDI covers by different authors played at the same time through OPL3 emulation. I had previously chosen the OMF music for it in June 2012, but I ended up using that song for the 1000 subscriber special instead (   • Q&A - NESemu1 CPU explained (1000 subscrib...  ) as this project got delayed. This video project took me many years to complete (with long periods of hiatus). The final pass, recording narration, took 10 days. Enjoy!

I'm making these statistics mostly for my own interest. P.S. While making this video I realized that the small pixel fonts such as the VGA 8x8 font are best for maintaining legibility of the text even at small sizes.
