Chipnsfx is a music software suite with focus on a lightweight code and data written by CNGSoft. The player routine is under 950 bytes long and can be as small as 550 bytes. Like all newer software the softwore focus more than one system, so you can produce music for the Amstrad CPC, Sinclair Spectrum 128 and the MSX1. Other platforms can be supported by minor changes on the player routine (e.g. the Sega Master System). The tracker was already used in several CNGSoft productions like Bubble Bobble for CPC, Hire Hare, Frogalot, etc.
