I agree. They're not real PCE chiptunes until they're running on the real system. But that said, it's nothing like the SID example you gave. I'm not 'sampling' PCE sounds and instruments. Except for the linear VS log volume steps, everything is to PCE spec. The period system, the simple 32byte 5bit waveforms, the 7khz 5bit single frequency long waveforms. Hell, I even use 60hz speed/ticks too. It's nothing like those IT2NSF setups. It's basically famitracker with the HES export function.
Eh, It's pretty much like the SID example. What if the mod tune is 3 channels and to "SID" spec.
people do that shit on other computers too and generate "SID" spec'd music. What if I use a VST that is emulating the SID? I could do that on an Amiga, a PC, a Mac, hell, even an MSX.
It's still using some other program/platform to achieve the sound, so until it runs on the intended platform, it's just playing around and mimicking things, even if you claim it's to exact specs.
This problem is complicated further by the fact that about 6 people would actually understand what "to PCE spec" means, and the rest would just go OH HEY THAT SOUNDS LIKE THE PCE, because it sounds close enough, and may not actually be (like when some people hear SCC music and think it's a PCE song and vice versa).
I could sit here right now, fiddle out some shit in fruityloops with 32 byte waves, post a youtube of it playing, and say its a PCE chiptune. I'm fairly certain people would think I'm being serious, even though it's nonsense... the average listener cares about the sound, not the stuff going on behind the scenes (on the hardware).. so it's our job to give them real stuff.
Hence: Real thing or gtfo.
It's kind of like mockups of games. It's better to give actual screenies of the game running, than it is to photoshop it. You can say "oh its to PCE specs", but it's still just some stuff you pasted together in photoshop. It's teasing people.
At least, this is how I view it all. I don't like teasing people. If it isn't blaring out of my turbob, I'm not sharing it yet.
