Said I wouldn't enter but I did anyway. This one feels very inspired by Rusty I'd say, maybe with a hint of Snatcher.
I tried to stay as close as possible to actual YM2413 limits (only 9 total notes of polyphony, only 1 custom patch at once), minus any note overlap since mono mode is not something found in this pluginset.
