It's a parallel cable, not a serial cable. If you have somehow connected it through a cable to something marked as a serial port on the computer, you've probably blown the transferer.
Did this particular cable use to work before? Did you switch to a new computer lately? Muck around with the BIOS settings? If so, those are more likely suspects to begin with.
If you get a new cable, make sure it's a 1-1 (one to one) cable, not a Laplink cable.

Writing to the ROM of a white Nintendo Power cartridge with a bleepbloop/smartboy flasher won't work. If anyone needs help with that, I guess I could help. Oh, and definitely get LittleFM. It's not like I'm partial or anything, but it's a pretty good thing to add to LSDj.

As I pointed out on BH, it seems like their house may be on the verge of being foreclosed, so maybe he's just doing whatever he can to make some money. I can have some sympathy for that I guess, but that thing that he's selling, that is what it is.

Ok, this was fun while it lasted. If you didn't figure it out, this is an obvious troll account, which belongs to another member of the forum.

Believe it or not, I have experimented with these things. A couple of pointers:

You can select multiple samples using select+B and then moving the pointer to extend the election, similar to other clipboard operations in LSDj. Once you've done that, you can press up and down to offset the selection. This also doubles as a copy function, and you can paste with sel+A. When you have a selection, you can also flip the selection horizontally/vertically by holding A and pressing left/right or up/down. By using these tricks and absuing symmetries in the waveforms, you can speed up the manual labor a lot.

You can also make other waveforms, like a sawtooth by moving up 1,2,3,4,1,2,3,4 etc amplitude steps. You can also try doing other intervals, but those have to be more than one octave up. You have the harmonic series dictating these notes:

Overtone.
v   Coresponding note.
1   Base note
2   1st octave
3   1st octave, 7 semitones (major 5th, G in a C scale)
4   2nd octave
5   2nd octave, 4 semitones (major 3rd, E in a C scale)
6   2nd octave, 7 semitones (major 5th, G in a C scale)
7   2nd octave, 10 semitones (minor 7th, A#/Bb in a C scale)
8   2nd octave

This take a little trickery to get right. In part because these are perfect intervals and slightly detuned from our modern equal temperament tuning, in part because, unlike the octave intervals, the other intervals don't line up to single steps, so you don't move the cursor the same number of steps to the right for each part of the superimposed waveforms. This makes each interval sound a bit different due to aliasing.

In practice, perhaps only index 3 (octave + fifth) is really useful, unless you want to get waves that sound "bad".

To figure out how many steps you should move the cursor to the right between each half wave, you calculate 16/x and that's the number of steps between each alternation. For example, for the 1 octave 5th, that's 16/3 = 5.333... so on average 5 1/3 steps between each step.

Now how to do this easily? Let's use some Javascript. Press ctrl+shift-j (if you're in Chrome) to open up the JS console. Paste the following. (Fixed!)

mod = 32/3; acc = 0; i=32; while(i--){console.log((i%mod)>=mod/2)}

You should see something like this:

This means, move the waveform up for 5 samples, leave the next 5 samples untouched, move the next 6 samples up, leave the next 5 sample untouched and so on. Vary the 3 in 32/3 for a different overtone according to the table above. Again, note that the higher overtones will sound ugly, and are also two octaves up.

Lastly, something you obviously must have done, but didn't address in the video, is to use the vshift value in the synth screen to move the waveform when generating it.

I would make a video about all this if I didn't hate my voice so much.

Yeah, just to clarify, I have no problem with him selling whatever hastily glued together turds he can make for whatever ridiculous prices he may come up with. The issue with this one is that he seem to be insinuating in vague terms, that this is something that it isn't, maybe hoping to hype up the price. And also a couple of things that are almost certainly lies.

"I don't know much about this, but it is fun as anything." Most likely, he built it, so he probably knows something about it.
"You can also install numerous games at once like pictured." Most likely preinstalled games
"For controls you plug in a generic SNES controller." You're plugging in his modified.SNES controller.

Oh, and he added this:
"-Due to the nature of this item I guarantee it to work but it is also being sold as is"
I wonder if he forgot "can not" in that sentence or what.

If he was more honest and straightforward about what he was selling, I would have no problem with the ad.

After a bit of investigate work by yours truly, I can only say don't buy.
