Alright, so you drag/drop S1 Kick.wav (onto ConvPCM.exe I'm assuming, though you didn't say), after, you had replaced S1 Kick.wav, what do you mean by "and renamed with my sample"? Do you mean, you renamed your sample to "S1 Kick.wav" to replace the old one? Or do you mean you renamed "S1 Kick.wav" to something else? I'm sorry, but I really do need you to be very specific in what you did. Step by step, without leaving out details. The only things I can think of right now are: You either, didn't drag/drop the sample onto ConvPCM, or you didn't assemble afterwards (I'm assuming you did both of these, and in this order, but your video missed one of them, and I'm having trouble understanding your description). The actual DualPCM sound driver itself is not included into the main game, and you haven't replaced the SMPS sound driver code as described in the thread I released it in. And it's still running the old Z80 driver with the old samples. Did you follow this page exactly 100% to the letter?
