It's only for a week though.

Do an arpeggio by putting the instrument in "pitch" mode and then use the S command to produce a chord.

I was sure this was going to be spam when I saw the headline.

I might be misunderstanding, so forgive me, but you can assign an envelope to any of the instruments in LSDJ.

That's an amplitude envelope, not a filter envelope.

JaffaCakeMexica, gay jokes stopped being funny when that thread went to the graveyard, mmkay?

Yep, highlighted as mentioned. However, if you *didn't* do that yourself (even accidentally) there may be a risk that the file is corrupted.

Just to avoid any confusion. Koji-Kendo has not been banned. That's just their choice of avatar. (An image showing the word "banned".) Also, here's the link to the album showing the mod:

When you rotate the polarizing film 90 degrees you get increased contrast on a backlit screen. Nobody says this aint so, just that it's already a known fact. I will also admit that your tutorial was nicely done. But, I take a scientific approach to things and I'm not, to put it frankly, in the business of stroking people's egos one way or the other. So when you're claiming that you have seen a biverted backlight and yours was better, you may actually be right! Maybe you're using a better LED panel or a better polarizing film material than what you have seen before. But if it's true, it's true for physical reasons and not because you said so. My advice is to try to approach the issue rationally instead of emotionally. You don't need your account deleted because someone disagrees with you on the internet.

That sounds great and all, but I've seen an inverted backlight and a biverted backlight. This beats them both in contrast, clarity and brightness. But if you guys are that aggravated by a simple title, than let me go ahead and fix that for ya.

Are you saying that if you would put in the inverter chip, the contrast, clarity and brightness would go down from what you have now? If so, would it go up or down from there if you activated the inverted palette mode in LSDj on top of that?

When you invert the screen by rotating the polarizing film, you don't just invert the black and white image, but also the spectrum of the light admittance. In the normal position, the screen has a green tint, and in the inverted position, the screen has a blue tint, or more toward pink as the case is on a DMG. This affects the way it looks using different light sources or lighting methods. This is especially true for a green backlight, as the contrast between the brightest and the darkest shade increases with the inverted polarization.

This isn't really anything new or unexpected per se. LCDs in the early days typically used the green position because it works better in ambient light. I have seen one or two monochrome LCDs in the wild (ie, not on Gameboys) using the inverted position and a white backlight.

Really though, I think what Apeshit was reacting to, and now me, is giving it a fancy name. You could give it a name that is simply descriptive, for example "Backlit screen with inverted polarization".

Cool, if you wanted to un-invert it you could just rotate the polariser 90 degrees

The point of rotating it in the first place is to increase the contrast when using a backlight. But that has the side effect of also inverting the screen. The point of "biverting", ie inverting the signal that goes into the display, is to restore the inversion from rotating the film.

That's a Fortune/Bitman clone with a different labeling. Interesting however how they also tried to make a variant which tried to look genuine.

Would you say A-ha - Take On Me has this musical quality?

I could do it for you.

The previous wave of spam was just regular advertising for fake university diplomas. This wave of spam was unrelated to either that or China in general.

(some documents claim duty cycle is never reset, but as far as I can tell it is).

This is still true. What's referred to is that the phase isn't reset to 0. What is reset when restarting the channel is the phase accumulator, so the phase is only reset back to the previous (iirc) 1/16 of a complete cycle.

FF17 (PU2 volume) is not used (just mentioning for clarity, not sure that was what you were implying).

Yeah, sorry I did mean FF25.

Edit: Btw glad to hear Gambatte is doing the trick. I only tested with an old version, which didn't work so well. Another one that does work is mednafen - surprisingly, as it's not even a dedicated Gameboy emulator.

The real problem here actually isn't as much GB emulation accuracy, as audio oversampling.
