This is a bit like if a hardware store (you know, the type that sells hammers and screwdrivers) called itself Pro Tools. Confusion could arise, but meh.

Moved to the handhelds forum.

I know nothing about that game, but as linked above, I have experimented with this technique. Nintendo were right in not allowing it, as doing this on a GBC and above looks like a proper flickering mess. The LCD is fast enough to respond to change each frame, meaning that instead of seeing the average of the two shades you're aswitching between, you now see a 30 Hz flicker.

However, Nintendo may have had more immediate concerns, namely with the Super Gameboy. First off switching colors on each frame on a CRT TV gives you annoying flicker, just like on a fast LCD.
Moreover, the SGB works by copying data generated by a Gameboy CPU in the cartridge, into SNES video RAM. However, as far as I'm aware, the SNES and GB CPUs are not running in sync. Instead, I believe the data is double or triple buffered, so one buffer is displayed while another one is being filled up.

However, the almost 60 Hz generated by the GB CPU might not always line up with the almost 60 Hz. So every once in a while, a frame might be skipped or duplicated. Instead of getting an even flicker, you get flashes of darker or lighter color when the same pixel is drawn with the same color for two frames in a row.

Even worse, is what (I believe) happens on a PAL SGB, where the SNES side of things generates video at 50 Hz and the GB side of things still at ~60 Hz. Now duplication of blinking frames will happen all the time you will get a truly flickering mess.
If anyone is able to try my gradient ROM in the post linked above on a PAL SGB, please do so and report exactly how much of a flickering mess it becomes.



This is what one variety of the newer EMS cart looks like. It has an Intel chip in the top left corner. What I'm looking for instead has 4 smaller chips marked with the text Atmel and/or the Atmel logo. A cart bought
in 2008 is most likely the newer variant with an Intel chip, so yeah...

Find someone who can flash the cartridge and get an LSDj ROM patched with LittleFM, which lets you transfer the sav data over a link cable. Makes a world of difference.
However if this happens to be the older type EMS cartridge which has 4 Atmel chips (unlikely) I'm interested in it for my own use.

Yeah, that's what reminded me of this function. Though, this function could be abused by more "real" spammers which would also not leave much a trace on the server, compared private messages. It's not only that it might be annoying to users to get spam addressed as being by "chipmusic.org mailer", but if such a spam attack happens and a lot of people mark these e-mails as spam, this could also affect other forum e-mail like signup nd thread notifications e-mails.
So I figured it was a good idea to turn it off by default.

In the interest of preventing spam, the function that allows users to send e-mail to other users is now disabled for all users. Users who wish to be able to receive e-mail from other forum members can still enable this function by going to profile in the top menu, then settings, select "Hide your e-mail address but allow e-mail via the forum." and update profile to save the setting.

This function is different from private messages, which are not affected by this change and work just like before.

Current (noted as I) is equal to Voltage divided by resistance.

I = V/R; V = I*R

That's how voltage works!

Well, yes and no. That's true for a purely resistive load, but in many situations and circuits, a too high voltage can be harmful (for batteries), or even a too low voltage (for switching power supplies.)

Where do you get the 125 V figure from?

Edit: The cable is just a cable. The voltage printed on it is the maximum voltage it's rated for, apart from that it will just carry the voltage from wall socket. There's nothing magic in it that will make it output 125 V if connected to a 120 V socket.

Wait a minute. I wonder why the adapter is marked with 125 V. USA is 120 V and Japan is 100 V. Maybe it's rated for 125 V to account for tolerances. (120 V actually means 114 V and below 126 V.) But under normal conditions, your wall socket will give you a lower voltage than that transformer is rated for. This is just a regular transformer (not a switching power supply) so the output will vary with the input. If the tranformer was designed for 125 V and you give it 120 V, the output voltage will actually be 4% lower than the normal output voltage. This won't damage anything but maybe the battery won't be fully charged. My guess is that 125 V is just overprovisioning, though.

I'm also unsure what "So I've got a few that are straight 125V, but one of them says 125~V." means. ~ in this case wouldn't mean "approximately" but AC. Even if the ~ is missing on the other packs, it's all the same, just different markings.

I'm just speculating since I don't own a Wii and can check this out. But from what I gather, there should be a folder like /vbagx/save on the SD card. If this file is exactly 128 kiB big (131072 bytes) it's likely a sav file with a different file extension. If so, just copy it to the computer and rename the extension to sav, so you might have a pair of files like lsdj.gb and lsdj.sav.

If the file is not 131072 bytes big, it might be a save state file. This might be what the autosave file you're talking about is. Ie, a snapshot of the running Gameboy so you end up right where you left off last time. Does that sound familiar with how VBA GX works? If this is the case, you may want to load the atosave file as described in the previous post, in VBA on the PC, as a save state, or SGM file.

If all that fails, give me whatever save file you have and I'll see if I can extract your data.

Just an idea, maybe you can load the ROM in VBA (preferably VBA-m) on the computer and choose file/load to load a save state. Hopefully, the format is the same. If that works, the VBA in your computer should spit out a sav file.

Yea but the wav channel only has four bits of resolution, so you cant really escape that?

The wave channel and master volumes work in different ways. The wave channel volume lower the volume by shifting each sample and discarding the lower bits. So in effect, wave channel only has 3 and 2 bits of resolution for the lower volume settings. The master volume does not have THIS problem but obviously affects all sound channels routed to that stereo channel.

Topic moved, and title edited to be overly clear.

Look for any settings related to automatic gain control or audio enhancement in the control panel and disable them. These settings are often on by default which makes sense if you plug in a microphone and use it for something like Skype, but not so much for recording music.
You now have to be more careful about watching the input levels and decrease the recording volume to the point that the audio doesn't clip.
