Mega EverDrive / Re: Pier Solar and CD enhanced audio question

« on: December 29, 2019, 11:59 PM »

Well, before my official pack arrived in the past I tinkered with the real cart and had a quite massive fight to get it working. WHICH image did you use? That one? http://www.piersolar.com/tmp/DiscAlternate.zip (official one AND official link!) http://www.piersolar.com/skin/aboutgame/esd_madeathome_lightscribe.jpg (official Lightscribe Artwork)
Try different burning apps. I am a big fan of IMGBurn but ppl in the now-dead official forums claimed Nero being a good idea here. I will try my official disk later today and tell ya.

EDIT: OK, tested newest firmware and Reprint A ROM no-intro verified. All works fine. Thus you made a burning error or used a wrong ISO.

Hi Dreimer, i used the image i found on this site:  https://edgeemu.net/details-17799.htm, i'm burning a new disc with the image from the link you posted

EDIT: Didn't work. Tried all the No Intro ROM files of the game, burned a disc with the image from watermelon site, tried two different burners and nothing. The only thing i can't try right now is a different brand of CD R, however my sega CD reads everything i burn with the CD R brand i'm using (Imation). And my sega CD is working fine too.

Well in that case maybe @mario64 has a idea? I use the official disk and it works.

your burned cd works or the original one? with the mega everdrive? on my jap megadrive mega cd model1 didn't work too. the game itself works, but if i put the cd in it light on the green led on the mega cd but not the access led wich is strange a lot and remain like this.

is possible to add the chip amp on the old model just like on the sd2snes? wich pin is the audio in?

Mega SD supports it just fine, even the enhanced CD soundtrack.

This.
So why krikkz not add support for it? Are mega edx7 users more idiots than megasd ones? Please krikkz respond

EverDrive 64 / force 60hz mode on pal game how? ntsc did nothing.

« on: April 19, 2019, 10:01 PM »

force 60hz mode on pal game how? ntsc mode did nothing.

there is a way to do it from everdrive os or from patching a game? i want banjo kazoie pal to run in 60hz please (translated game)

paladin not worked

james i'm not the only one that say the everdrive chip sound is too much low on famicom.
Famicom have low chip sound when using original carts? NO. So is not the famicom the culprit here. I have a fantastic sound when using my famicom, instead very very low when using the everdrive exp chips. Everyone knows that you are a fanboy of everdrives and sd2snes so you never talk bad about these, but i'm not like you. Also i haven't a av famicom like you so i can use that to fix all my problems. You can't understand so. 

Everdrive chip sound is low and that is a FACT on the famicom.


PS. also what you quoted of all my post? only where i talk bad of the everdrive....no words.

Let's add it again: lowering the apu sound is USELESS. You got only a low famicom volume, forcing you tu increase volume on tv and hear a lot of interference/noise sound in the tv because input sound is too much low.

Okay, so apparently the expansion audio mod for the NES, and the Famicom mod necessary would be two different things.  I've done the former, not the latter.

It sounds like for the NES, you would want to reduce the resistor value, which would increase the volume of the expansion channel.

For the Famicom, if R7 controls the stock audio channels (but not the expansion), then the solution is instead to lower the stock channels audio level to that of the expansion cart.  Then you can just increase the volume on your TV.

Someone correct me if I've got this wrong here.  I'm also not sure which direction does the lowering on a Famicom system (increased or decreased resistance).

a decrease in the resistor value = a large amplitude and current = that is, a louder sound.
 but alas: reducing the volume of Apu (five-channel sound of the processor) - and forcibly increasing the volume on TV - can increase the unpleasant background at a frequency of 50Hz (buzzing), from which there is no cure ...

THIS.

apu sound is on the ideal value, everdrive chip sound NOT.

@oilvil
You are confusing the feedback resistor in the output amplifier every famicom has we are talking about, with the NES expansion audio mod, two completely different things.

@Sarge
Yes, 47k is what a HVC-GPM-02 has, 100k on the HVC-CPU-01 to -08.
Arnold101 is wrong about the noise floor, since the output amplifier is the last in the audio chain thus will lower the noise along with the audio.
Putting a pot instead the 100k will indeed have the desired effect.

i want to install the pot. is 100k i need? can you show wich resistor is on the famicom pcb?

Famicom stock channels get mixed through resistors, then go to an inverter gate with a feedback resistor (R7) that acts like an amp. It then goes to pin 45. If the game has stock audio there's a bridge that goes to pin 46, if not it's mixed to extra channels in the cart then goes to pin 46, and from there it goes to the RF unit.

100k is the original value, later revisions changed the value.

Lowering R7 lowers the stock channels volume.
Note that you can't apply that as-is to AVFamicom (for extra channels mixing) because the inverter in it has lower voltage maximum.

SO...the resistor is NOT for chip audio but for stock channels? So nothing here can boost the chip sound.

My guess is that dropping the resistance value (mine is 47K, for instance) would amplify the expansion audio signal, which is why having a potentiometer would both allow you to increase the volume of the expansion audio, as well as balance it as needed depending on the source (real cart or EDN8).  If I'm not mistaken, a real Famicom uses somewhere in the range of a 100K resistor.  Dropping that value should give a louder signal, at the expense of having real expansion audio carts sounding too loud (which is why a pot is a better choice if you're dealing with multiple sources).

See this topic:  https://krikzz.com/forum/index.php?topic=692.0

can you show a photo of where is located the resistance that control chip audio? thanks

you have installed a pot or not?

yeah but the chip sound would be low anyway, you help only with balancing, nothing more.
