(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.

This is NOT what I was expecting! The predictable thing would have been to use bit 3/7 of FF24 to create a square wave and the timer to generate frequencies. Instead, you are using using channel 2 to generate a DC offset and abusing its volume control to generate two interleaved PCM channels, as far as I could gather from a quick look at the code at least. Not necessarily what I would call a 5th channel, but really innovative!

As far as emulation is concerned, Gambatte does a good job of emulating it, if sound resampler is set to high quality (polyphase FIR) or higher, which it should be by default I believe.

Posted on March 32nd. Definitely real.

It's usually just called a (linear) polarizer or polarizing film. Are you interested in the chemical composition or do you just want to buy some? I wouldn't hold my breath for finding it locally, but it's readily available on line. First Google result for example: http://www.polarization.com/polarshop/
If you are on a zero budget or wish to have some fun, try doing a teardown of an old/broken monitor. You will find a sheet of polarizing film as one of the layers in the LCD panel.

How do you suppose that would work on 32k?

The DMG is using a switched mode power supply which works from pretty much anything from 4V-9V as long as it can provide enough current. 5V will work fine. 5V is not unusual for a set of slightly discharged batteries anyway.

Oh, actually... ALTANE always flips the reset line at startup to make sure the cartridge is in a known state before doing any operations. This means that it should always consistently access page 2 and never 1. I always assumed that was a problem with my cart. (Which I once got sent as being faulty.) I could make it not touch the reset line so that it can access page 1 as well. In the meanwhile, you should be able to access what ALTANE wrote to the cart but by turning the power on-off-on quickly when the cart is in the *Gameboy* to move the cart to the page that the flasher wrote to.

Should I delete the new account?

This problem should be fixed now.

Anthony, you should be able to do that edit yourself if you go to page 1 and click edit on the top post. However, you obviously need to be logged in as NonElectronics since that's the account the post was made as.

Don't disconnect the ALTANE. That will make the software lose its connection to the hardware. You could still do it while it's not running. But I'm still not really fond of the "USB cable with a switch" idea. The only two known ways to externally change the page as of now are to manipulate the cartridge power supply (removing/inserting the cart and so on) and through the cart's own USB port (as EMS's own application does.) Someone did once post a trick where you would short a certain point on the cart PCB to ground to permanently activate one page. Maybe this can be done with a switch where it either connects to ground or +5V. Just a thought.

I sent a pm to you DOS4GW.

Moved from general discussion to releases.

It feels sad to have to revive this thread, but the current state of affairs is that the affected domains point to a Google search for "kitsch-bent" instead of to kitsch-bent.com. Just a marginal difference to the previous situation, I think. And still no really straight answer from Matt.

In other news, kitschbent.com (no dash) has just entered pendingDelete status and will soon be released.

The closest you can come to this is to use the pause function. Whenever you pause and unpause, a new audio file is created. If you're recording multiple tracks (which I'm guessing is your use case?) you can pause-unpause before and after each track and later delete the unused silent files. You can configure a shortcut for pause by checking configure extra buttons, then pressing configure game controller.

Otherwise, my own guess is that it's unlikely that beware will implement the function exactly as you requested it.
