Minty

MultiCart for Mattel Intellivision

Introduction

Multi-cart based on Raspberry Pi Pico hardware and PiRTOII firmware (https://github.com/aotta/PiRTOII)

Features

• Pico C/C++ code refactoring
• Intybasic code refactoring
• no more config files for "official" ITV titles
• new navigation keys for UI ROM
• new color schema for UI ROM
• support for long filenames (up to 255 chars)
• move from 64 to 512 max number of files for directory
• SD support (with sukkopera board: https://github.com/SukkoPera/PiRTOII)
• Intellicart ROM support (.rom)

Getting started

To simply program Pi Pico:

• connect it to your PC/laptop using an USB-C cable while pressing Pico on-board button (boot MODE)
• drag and drop inside root directory Minty.default_board.uf2 (for PirtoII default board) or Minty.sd_board.uf2 (for PirtoII board with microSD slot)

Setup ROMs:

• copy your ITV ROM to flash (or microSD) root directory
• if ROM name is included in cfg/0game-maps.csv you do not need to add config (.cfg) file
• enjoy your PiRTOII cart with Minty firmware !

User can switch flash/SD storage device using controller key.

Build (TL;DR)

Requirements

• Pico-SDK (https://github.com/raspberrypi/pico-sdk)
• CMake (>3.13)

Commands

mkdir build
cd build
cmake -DPIRTOII_VARIANT=DEFAULT_BOARD ..   # for default PirtoII board
   or
cmake -DPIRTOII_VARIANT=SD_BOARD ..       # for PirtoII board with microSD slot
make

After compilation Minty.bin and Minty.uf2 are generated.

To use Minty.bin to flash PiRTOII cart picotool is required. Run following command after setting Pi Pico in BOOT mode:

picotool load -f Minty.bin; picotool reboot
