Well, my mother language is portuguese. Needless to discuss that, as we're going offtopic. I really hope this isn't a sign of disrespect though. :(

Attempting to stay on topic...I wanted to note that when I threw my NES into overclock and restarted the program, it detected as PAL, and the playback jumped from about 14750Hz (Approximating) to about 19000Hz...lol.

Oh man Rickroll.nes...I'm gona have fun with this...

Just a heads up I posted a video here in the case (like I had) where they (target victim) refuse to run the nes file in a emulator due to incompetence/laziness.

How do you convert sound files into 7-bit PCMs?

Here to at least get an idea of how the NES works. I mean I know alot of the basic things, but this place'll help me grasp more how NES functions.

Make it an 8-bit mono WAV file, and clip off the header (I don't know how big it is, exactly). For each value in the file, load it, shift it right once, and store it into $4011. Then change the time interval between $4011 writes to match the frequency of the WAV file. So if it's 44 KHz, you'll want to write to $4011 44,100 times a second. That's 735 times a frame, which is about once every 40 cycles. I'd recommend not having 44 KHz, because that is horribly space-consuming. But you'll pretty much have to sacrifice one for the other: either space or quality.

I used sox to make some 4011 playback roms. i converted some wavs to raw 8bit because i remember i had some trouble getting it to output just 7bit. no problem though, just right shifted it before the write.

there are ways to turn an 8bit wav into a 7 bit wav in a wav editor :twisted:

I got Adobe Audition.
It can save into many formats but none of them can save as a "7 bit PCM".
Even on "save as raw PCM" it only saves at 8 bits.
