Multi-cart for intellevision

Hi Folks,

Please find below some information to make your own multi-games cartridge for your Intellevision console :


You can find all the details on the original author site :
Aotta's github

In order to build your PCB you will need the following gerber files :
gerber

In that version (alpha) you need to patch the PCB are visible on the picture, to ground one of the pin of the cartridge.

Here is the BOM :
- Two standards leds :
D1 : LED (power on)
D2 : LED (status)
- Resistances :
R1 : 220 ohms
R2 : 220 ohms
R3 : 1k ohms
R4 : 1k ohms
- Capacitance (104)
C1 : 100nF
C2 : 100nF
C3 : 100nF
- Push buttons 4Pin 6x6x5mm
SW1 & SW2 : switch
- Integrated Circuits :
U1,U2,U3 : 74LVC245 (Dip 20)
Teensy 4.1 (Look at thepihut.com to find affordable version)
- Led screen :
Oled Module 0.91" (For Arduino)
- Support :
For the Teensy & Led screen

Once everything is soldered on the PCB, you will need to program the Teensy 4.1 using IDE softare for arduino.
You may have to install missing libraries and device components for the Teensy 4.1

You can then use my own version of the software, adapted for the Secam (french) console :

The remaining complex step is to writea .cfg file corresponding for each game you install on the SD card.
All games that required the ECS are not supported.

Enjoy,
