I am completely fine with this FTM. I don't see how this is any less "show off your work" than a lot of other cover efforts we've had.
It's "show off" all right, but it's not "his work".
Imagine if I took an FTM of yours and just transferred the 2A03 channels to the N163 or something. That wouldn't really qualify as the result of a creative process on my part.
It's not the most interesting post ever, but he did "something" to the track. It may not be a lot, for the most part just repetitive V0x effects, but it's still something.
I didn't like this at all. It looks like you just copy-pasted the square channels, then replaced the duty cycles with something sounding C64-ish. The sound was perfectly fine originally before C64-ifying it.
I think moving a tune onto another chip is a neat experiment. It just so happens that this one used the same tracker to do so (and kept the 2A03 noise)
