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!

![How did they Program N64 Development Flash cartridges? - N64 Flash Gang Writer Full Demo! [#14]](https://i.ytimg.com/vi/yKRxFmzJ6ek/mqdefault.jpg "How did they Program N64 Development Flash cartridges? - N64 Flash Gang Writer Full Demo! [#14]
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!!

This is a hardware demo of the Intelligent Systems IS-AGB-CAPTURE device. The unit was used for streaming the Gameboy screen onto a Television, and also providing a computer interface for capturing screen shots of the game during runtime.

![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

![Strange Nintendo Game Boy cartridges! - The iCardPRO & Aprilia DITECH [#38]](https://i.ytimg.com/vi/ztXafLelfdQ/mqdefault.jpg "Strange Nintendo Game Boy cartridges! - The iCardPRO & Aprilia DITECH [#38]
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.
Those interested in watching the FULL hardware demo for the IS-AGB-CAPTURE unit...you can watch it here: https://youtu.be/zBYTZIGmHPE
