Computa games
April 13, 2016 (Wednesday)
25 years ago in the course of the 1990-91 school year, as my third grade class visited the computer room for the first time I remember playing Computa games (FR: Jeux de calcul) by André Normandeau. Today, following an interview with the author, I have the pleasure of relating how this educative math game came into existence, and I am delighted to offer an online version.

Do you remember playing it? Try it with your kids, it's fun!

Third generation of my GC/N64 controller to USB adapter image
This new version, based on my Multiuse PCB-X board, beats previous versions in performance and features:
  • USB full speed (12 Mbit/s)
  • Very low latency (approx. 6ms worst case)
  • Configurable controller poll frequency (Maximum 500Hz)
  • Firmware update possible and easy
  • N64 mempak read/write
End of page bonus: Latency explained: What is latency, how it happens, how we can minimize it and a raphnet vs. competition comparative table.
PPUSBCOMM: USB to Parallel port file transfer image
PPUSBComm is a tool to copy files from a Linux system with USB ports to a system running DOS with a parallel port. I created this tool to send games and software I download to my Tandy 1000 EX.
Multiuse PCB-X : A small multipurpose PCB with an USB micro-controller image
This USB-specialized circuit board design is inspired from my previous Multiuse Tiny 1 and Multiuse PCB2 projects. This time, since a micro-controller with native USB support is used, it is possible to transfer data at 12 Mbit/s (Full speed) unlike the older designs which, due to the use of a software-only USB implementation (V-USB), were limited to 1.5 Mbit/s (Low speed).
CGA to VGA converter using an FPGA image
CGA to VGA converter using an FPGA
November 28, 2015 (Saturday)
I simply wanted to have fun with an old Tandy 1000 EX computer, but the image quality using the NTSC video output was unbearable. The alternative was to use a CGA monitor of course! But as I don't own one, I started looking at how I could build a CGA to VGA adapter, which I was able to build using an FPGA development kit. The project was the perfect excuse to acquire one. See the page for notes, explanations, schematics and source code (at your own risk).

MarkIII cartridge to Megadrive/Genesis adapter image
When I was designing my SMS (non-Japanese) to Megadrive/Genesis cartridge adapter, I learned that the Japanese version of this console used a different connector (44 pins instead of 50). So I decided to also design an adapter for Japanese cartridges.

September 7, 2014 (Sunday)
A 4x SNES to USB adapter built in a beautiful enclosure machined from a solid block of aluminium with a black anodized finish.
SMS cartridge to Megadrive/Genesis adapter image
I had known for a long time that Sega Master System (SMS) games can be played on a Sega Megadrive/Genesis (SMD) console using a simple 50 to 64 pin adapter, and thought a few times about making one. So when I was told my SNES to SMD controller adapter did not work when a SMS game was being played, it was all I needed as an excuse to design and build an SMS to SMD adapter.
New entry in the NES mods page: Using SNES controllers on a NES image
It has been known for a long time that using SNES controllers on a NES was possible and easy to do using simple wiring. So this is nothing new, but since I recently built such an adapter, I just thought I'd document it on this page.

  • Optimized I2C code
GC/N64 controller to USB version 2.9.1 image
Minor fixes and improvements:
  • Prevent 8bit overflow from occuring. Helps some cheap 3rd party controllers that have the "Left not working" problem. (Thanks to this fix, those "should never be bought" controllers change from "totally unusable" to "frankly not very good")
  • Fix non-working timeout when waiting for the controller. The adapter now enumerate without controllers as it used to.
3 Channel video buffer image
3 Channel video buffer
April 13, 2014 (Sunday)
Having been in need of a video buffer for two projects[1][2] in a row, I thought it would be nice to have a small circuit board with all the required components. So I designed one.
Possible uses:
  • Adding composite video outputs on old consoles.
  • Video amp for video game RGB mods.
  • Video buffer/repeater (eg: To display the same picture on multiple monitors)

VirtualBoy controller to USB adapter
March 1, 2014 (Saturday)
So you want to play with a Virtual Boy emulator on your PC, depriving yourself the pleasure of adopting an unpleasant posture and of getting a headache? At least, don't go so far as to deny yourself the privilege of holding the real controller in your hands! (Ok, I admit I never really tried a real Virtual Boy. Maybe it's not that bad...)

Anyway, in order to use a Virtual boy controller on a PC, I designed an adapter. The schematics, wiring and source code are on this page.
Repairing a Commodore 64 image
Repairing a Commodore 64
December 21, 2013 (Saturday)
I won a « commodore 64 - working » on a popular auction site. Well there must have been some mistake for the machine I received did not actually work. And I wanted a working C64 right now. Returning it and trying to win another one would surely take too long... So I got a partial refund (« Working » auction converted to « As-is - untested ») and impatiently began the repair.

Visit the page to read about the repair details and an unexpected issue with my LCD TV (+ its complicated solution).
Zaisu image
Zaisu
December 8, 2013 (Sunday)
I own a kotatsu (炬燵), that is a low Japanese table covered by a blanket. An electric heater placed underneath warms the kotatsu. By sitting with the blanket draped over our legs, we manage to keep warm in winter despite the lower house temperature. But sitting on the floor and on your legs tends to become uncomfortable after a while. Also, fully extending the legs under the table to catch more heat is difficult without something to rest your back. The japanese Zaisu (座椅子) chair is a perfect solution. This is like an ordinary chair but without legs. But as these are rather rare here in Canada, except in specialized (and expensive) importation stores, I decided to build my own.
GC/N64 to USB project: Gamecube keyboard support added to firmware v2.9 image
The Gamecube keyboard is now supported and can be used normally under Windows and Linux. Note that I only tested ASCII model ASC-1901P0. This keyboard has a dual-connector cable. The gray connector is for the keyboard function and the purple one for the Joystick function. To use both functionalities simultaneously, two adapters are required. As this is a Japanese style keyboard, there are a few unusual keys and many won't produce the labelled characters unless the PC is configured to use a Japanese Keyboard.
New Dreamcast to USB firmware adds Keyboard support image
New in version 1.2:
  • Dreamcast keyboard support (Tested: HKT-7600 and HKT-4000)

Dreamcast controller to USB adapter project: Progress, transmission is a success image
I began writing the firmware. First step, implement a transmission routine in assembler to achieve a timing identical (or very close) to what is shown on http://mc.pp.se/dc/, but also to what I see on my Dreamcast bus with the scope. Status: Transmission is a success. But looking at the result on a scope is obviously not very useful, so the next step is implementing reception. More fun to come!
SNES controller to Genesis/Megadrive adapter: Update image
Implemented Atari/Commodore support:
  • Two selectable button mappings
  • Enabled by grounding PB1. Note: A slightly different DB9 wiring is required.
Beginning Dreamcast controller to USB adapter project image
I have received many requests and while I had been looking forward to the challenge of building this adapter, due to other not less interesting projects, it took a very long time before I finally began working on it. This time, following a suggestion and contrary to my habit of only posting projects in their completed form with the source and schematics, I decided to create a build log page I would update as things progress.

Two NES/SNES controllers to USB adapter image
This is a two player variation of my 4nes4snes project. The firmware is modified to expose only two controllers to the PC, preventing two extra controllers from needlessly appearing if an two player adapter is built.
Extenmote: NES, SNES, N64 or Gamecube controller on Wii or Wii U through a Wii remote. image
The gamecube ports have been removed from the new Wii consoles and the Wii U does not have any. This new project works around the problem by using the Wiimote extension port like the classic controller does. This provides a way to play virtual console titles with the original controllers again on the Wii U and regular Wii consoles (with or without gamecube ports).
2013-01-30: Version 1.5 now available!

The Famicom controller II does not have select or start buttons, but it has a built-in microphone! This new firmware makes it possible to use the microphone as a button.
Small project: Plastic bag sealer made from spare parts image
I was looking to ship small electronic components in anti-static bags, reusing the bags I had on hand, but they were all too big. The obvious solution was to cut them to a reasonable size and seal the edges with a bag sealer. However, I did not want to buy one so I built this simple version using components I had in stock.
N64/Gamecube to USB : Rumble Pack / Vibration finally supported! image
The new firmware version 2.0 adds support for the long awaited N64 Rumble Pack and Gamecube vibration feature! Special thanks to Sean Green for providing an updated device descriptor and an example main.c from his own project for me to use and finally implement this feature. Without this, I don't think I would have ever taken the time to add this feature.

About me

Hello, I'm Raphaël Assénat. I live near Montreal, a city located in Quebec province, Canada. I have two big passions in life: Computers and Electronics. Those two disciplines allows me to quench my desire to create things, my curiosity, and my desire to learn. I'm always working on many projects at the same time and I do not have enough time to do all the projects I'd like. But fortunately, once I begin working on a project, I rarely stop before it's finished.

Programming is my main hobby, and I like to do it using C and assembler. Preferably, on Linux or Unix platforms. I'm not interested at all by windows programming. What I like the most is when I have the chance to work on projects involving both programming and electronics. For instance, writing software which controls external circuitry designed by me, or even better, programming microcontrollers.

Other than computing and programming, I like to play piano and enjoy relaxing by playing RPG video games. (And thus many projects on this site are related to video games...)
