Beginning as a management consulting firm in the 1970s, the company converted to contract software development in 1980 and produced several Intellivision titles for CBS/Coleco and Parker Brothers in the USA. They also produced games for the Atari VCS, 5200, Apple II, Atari 8-bit, C-64, IBM PC, TI-99/4A, and VIC-20.
Roklan was a big deal in the arcade->console porting business. A disassembly of multiple Coleco and Parker Bros games seems to indicate that the same Roklan tool chain and coding patterns were used.
