Hello,FBA dev,first I say I'm not Cave fans,so about Ketsui I have nothing to say,I have a question that some months ago Haze has improved toaplan stuff a lot,and almost all toaplan game (include Batsugun) worked perfecet expect sound,and Haze says sound(toaplan2 driver) will be easy to be emulated,but because of somebody annoying him about the sound,then he says :"We’ve decided to stop working on Batsugun and other Toaplan games ,Sound probably won’t be added for another year or two now."I think it's too pity,If the sound can be full emulate,you can find the sound listens very well
