🎮 FM Sound Is Now the Default Experience
From this update onward, FM Sound Mode is the new default for Battle AirForce.
The signature YM2612 tone — with its rich overtones and expressive LFO — adds new depth to every mission.
If you’d like to revisit the previous version, the original VGS Sound Mode remains available via the Options menu.
