Description

SFG BASIC is a BASIC extension that is only available on the Yamaha FM Music Macro cartridges:

• International product codes: YRM-104 and YRM-504 (also a limited version of the YRM-501 cartridge)
• Japanese product codes: YRM-11 and YRM-51

They need to be used on a computer with at least 32kB RAM, equipped with a Yamaha FM Sound Synthesizer Unit, generally the SFG-01 or SFG-05 module, more rarely the SFK-01 module.

Instructions

SFG BASIC adds 36 or 37 new instructions, according the used version.

Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info. Besides, only the first four characters of each SFG BASIC instruction are interpreted by the computer.

(*) = only with YRM-104 - (**) = only with YRM-504
