Carnivore2 is a multi-function MSX cartridge developed by the Russian Bear Service Crew (RBSC) in 2017.

The project was released as open-source and several manufacturers were authorized to produce the cartridge commercially.

The 8bits4ever and Carmeloco officially produce and sell this cartridge. Also, the cartridge is produced by the new RBSC member SuperMax in Russia.


  • On the Arabic and Korean MSX machines a different boot block and main utility must be used
  • The first batch of cartridges produced by RBSC had tinned slot pads, the cartridges produced by 8bits4ever and Maxiol have gold-plated slot pads (fingers) but other makers not.

Price: About €100-€115 including shipping costs worldwide.

Note that the Carnivore2 is manufactured by several people. Prices vary between €70 and €115, the quality of manufacture also varies. Tin-plated contacts are frequent.
