Laser 2001 and Salora Manager games were released without keyboard overlays.
*** NOTE ***
This cartridge was first spotted in 2018. It is believed that the ROM could be different from the common CreatiVision release. When playing the CreatiVision release on the Laser 2001 and Salora Manager computers, the joystick buttons operate the bats swapped (left/right). The Laser 2001 and Salora Manager versions (which we have not tested) are believed to have a different ROM program that makes the buttons work correctly.
Any information on this release is highly appreciated!
