********************** ATTENTION **************************
This is PART#6 of my overall N64 Programming Primer Series...however it is
Part-3 of us covering the "LIGHTS" Demo. I will make this clearer in future Demos.
Apologies for the confusion.
*************************************************************
(Lights DEMO Part #3)
In this video tutorial we go over one of the LibUltra SDK demo's....that being the "LIGHTS" demo. In this part 3 of covering the lights demo, we talk about the main C source code file's Game Loop...(WHILE LOOP), microcode, and as well... the concept of the Frame buffer.
As we move forward in this series, I will continue to share N64 development tips and some of my own Homebrew code. I will also review various N64 Demo's from the SDK, and will try and explain how the N64 code works line by line, and go through the flow of code from console startup.
For further reading on N64 Programming, definitely check out the online manuals:

If you need some help installing the N64 SDK and Libraries onto your Windows PC, there is a Video on YouTube you can watch that will guide you through this process....but read this note below first:

![Learn how to write code for Nintendo 64! N64 Programming Tutorial PRIMER PART-1 [#17]](https://i.ytimg.com/vi/wLHQDkL7tGE/mqdefault.jpg "Learn how to write code for Nintendo 64! N64 Programming Tutorial PRIMER PART-1 [#17]
NOTE: This Video was re-uploaded due to a re-edit.
This will be the first video tutorial of an ongoing N64 programming PRIMER series, where I will share N64 development tips as well as my Homebrew code. I will also review various N64 Demos from the SDK, and will try and explain how the N64 code works line by line, and go through the flow of code from console startup.
Below are the TIP Links from this Video:
Tip #1
Definitely get some experience programming using the C programming language....as that is the majority of what you will be using to program on the N64. You can use Assembly as well....however C is the software of choice for most. So Brush up on your C Programming Fundamentals. If you need some help learning C, then I recommend the Video Tutorial Series by TheNewBoston YouTube channel.
Link below:
https://youtube.com/playlist?list=PL6gx4Cwl9DGAKIXv8Yr6nhGJ9Vlcjyymq
Additional Video:
Here is a FANTASTIC!! lecture that explains Pointers in C programming...so well done in fact, that I find I will go back and re-watch this every now and then. A really great lecture by Professor Richard Buckland from UNSW (University of Sydney Australia).
https://youtu.be/Rxvv9krECNw
Tip #2
Start out learning a little bit of OpenGL programming....Legacy versions if possible. The N64 hardware was designed by the company SGI who essentially created OpenGL. Here is a really good set of OpenGL Tutorials for Game Graphics:
https://youtube.com/playlist?list=PLRwVmtr-pp06qT6ckboaOhnm9FxmzHpbY
Also here are some excellent Legacy OpenGL tutorials:
https://nehe.gamedev.net/tutorial/lessons_01 05/22004/
Tip #3
Learn how Matrices are used.
Learn all ab out them for use in Graphics.
The 4x4 matrix. Here is an absolutely FANTASTIC!! series of tutorials explaining how Triangles and their points are stored in a 4x4 Matrix:
https://youtube.com/playlist?list=PLzH6n4zXuckrPkEUK5iMQrQyvj9Z6WCrm
Tip #4
Get very familiar with the N64 Graphics Pipeline and OpenGL...Matrix Transformations. Primarily how Model-View-Projection
Here is an excellent video explaining this for OpenGL:
https://youtu.be/-tonZsbHty8
N64 Flash Cartridges:
The 64Drive flash cartridge from Retroactive.... is a fantastic development tool for N64 Homebrew enthusiasts and N64 developers. Unfortunately you cant order them from the website right now as they are having issues with manufacturing....so check back in the future or try eBay: http://64drive.retroactive.be/
The best solution for an N64 Flashcart right now is the Everdrive64 X7 model wich has USB support for debugging and quick loading or your ROMs for test: https://krikzz.com/store/home/55-everdrive-64-x7.html

In this video I perform a Hardware and software demo of a Game Backup unit for the Super Nintendo called the Game Doctor SF7. (Released by Bung Enterprises) I focus primarily on demonstrating the loading of homebrew ROMs over the Parallel port from a Dev PC. This process is rarely demonstrated here on YouTube. Enjoy!

NOTE: This Video was re-uploaded due to a re-edit.
A full Hardware and Software Demo of the Nintendo NU64 FLASH GANG WRITER. This system was used by game developers in the late 90s to program N64 Development Flash cartridges, sending out N64 games under development to Game Magazine companies performing Game Reviews. Cartridges were also sent out to Developers performing Game demos at various Videogame Expos around the World!.
I demo the full functionality of this unit with the DOS software and also show the process of programming an N64 Flash cartridge. I flash a special IPL boot loader for the 64DD dev systems onto the flash cartridge. I then show it booting my 64DD development prototype unit. A very rare piece of N64 development hardware!!

![Display text on an HD44780 LCD using VHDL code - FULL Tutorial PART 3 [#10]](https://i.ytimg.com/vi/zQWwoLYBX5I/mqdefault.jpg "Display text on an HD44780 LCD using VHDL code - FULL Tutorial PART 3 [#10]
NOTE: This Video was re-uploaded due to a re-edit.
- PART 3 of 3 -
This is an Instructional video series that I have put together to explain the fundamental concepts and signal requirements for driving the HD44780 LCD display unit using the VHDL hardware description language. This VHDL code has been compiled to be used with the Altera Cyclone II FPGA on the Altera DE2 development board. However, you can modify the code slightly to port it to other development boards or FPGAs and CPLDs.
In this video I review the Clock signal requirements and also go into detail regarding the LCD core State Machines clock source signal: clk_400Hz_enable
Many of you were confused why this Variable name was being used and what was the reason that a 400 Hz signal was needed.
I review all of the VHDL code behind the clock signal generation and also explain how the LCD_E (LCD enable Port) is affected with these clock source signals and the reason for its use. I try explain everything in Layman terms and use analogies with the hope that the fundamental concepts can be understood.
Technically VHDL is a Hardware Description Language and is actually not a Program. It is merely a set of instructions on how to interface the the digital logic connections. With that said, I have tried to explain things in terms that can be easily understood. So just be away that VHDL is a Hardware Description language and is technically not a Software program at all.
In regards to this Project:
New links will be added to the devoted webpage on my Website where I will provide further images and information and also extra links to other files such as the VHDL code source files for you to download. http://www.digital-circuitry.com/Projects_LCD_DISPLAYS.htm

In this video I do a cool Show-N-Tell of two very Strange and Rare Gameboy cartridges. The first cartridge is called the Aprilia DITECH V2 Interface cartridge, which is used for programming Aprilia SP50 scooters ECU modules. (Engine Control Units)
The second cartridge is probably one of the rarest...or possibly the strangest...lol
This cartridge is called the iCardPRO and was a real-time racetrack telemetry information cartridge. It was a cartridge with a Radio transceiver that would display racetrack stats on screen.
