A nice group that released one or two works a year while doing all the programs, scenarios, graphics, music, etc. by themselves. It was characterized by complicated scenarios and beautiful pictures. However, only their programming technology was not that good, and most of the works are composed only of BASIC (only BGM uses the extended BASIC of OPLL Driver ). Most of them were dedicated to turboR, probably because of the speed and the need for a RAM disk . Furthermore, since the graphics were uncompressed, the number of disks tended to be a lot.
