EverDrive N8 / Re: Konami VRC7 Mapper Support Package
« on: July 01, 2017, 05:33 AM »
After scouring the interwebs, I found some authentic, unprocessed recordings of Lagrange Point audio from an AV Famicom provided by rainwarrior at NESDEV:

http://rainwarrior.ca/projects/nes/lagrange_point_ref.zip

As some of you may know, you can do a sound test of the game by holding A+B on controller 2 while resetting the game.

Even with the latest version, as I said before, the bass channel is significantly lower in volume than it should be in this mapper. The perfect scenario would be to raise the bass channel and lower the PCM drums, although I'm sure it's not that easy, since Necronomfive did mention getting clipping with the mix as it currently is.

Here's the NESDEV thread from where those recordings I posted originate:

I'm not using just the youtube video as a reference, that's merely the only one I could link to you. And this specific cue (and entire soundtrack) doesn't have anywhere near the same amount of post processing as the other videos on that account (almost none). I have no recording of the original cart to share with you but the difference in the overall level (not crispiness, cleanliness, or some other intangible subtlety) of the channel being used for bass tones is so egregious that it has to be a legit mixing issue. I work as a sound engineer in post-production for feature films myself, so I'd like to think my professional background would give my findings just a little bit of legitimacy. If you have a Lagrange Point cart available to you, try the comparison yourself.

After some further testing of this mapper, I think I may have figured out why the drums are sticking out so much. Whatever channel in the VRC7 that's used for bass in a lot of the music cues in Lagrange Point is exceptionally low. Like REALLY low. It's tougher to notice with a small speaker on a PVM, but once I hooked my console up to my big system I spotted it right away. The music cue where it stands out the most for me is this one:

https://youtu.be/drwX7MbB_IE?t=13m35s

(skip to 13:35 if it doesn't do it automatically)

The bass on here is very easy to hear. It's nice and full and you can almost feel it. It's almost nonexistent with this mapper.

If it's any help, I do believe there are two synth channels being used to create the bass tone in this and a few other cues; one for the high end of it and another for the low end.

I believe that if this is remedied, the drums won't be sticking out as much as a result.

I'm not keen on it either, which is why I have the Akumajou Densetsu cart in my AV Fami as a control in my tests. Like i pointed out, the VRC6 mapper is basically identical between the EDN8, Nestopia, and the cart for me.

I just ran the new mapper on my NESRGB-modded AV Famicom.. The 2A03 channels still sound a bit on the hot side, but it's close enough for my liking. I also have an Akumajou Densetsu cart that sounds perfect and damn close to the aforementioned 75% VRC6 mapper, so I know the expansion audio is running properly on my console, but I do not have a Lagrange Point cart to run for comparison. Still, it's close enough to how Nestopia sounds that I'm happy with it. Thanks again!

BTW: I couldn't care less about the clipping potential, I'll risk that in order to get a better mix.

PS: I just did some tests... Did some A/B comparisons on my AV Famicom and Nestopia through the latest Retroarch:

• VRC6 75_70 mapper on the EDN8 and the Akumajou Densetsu cart, and Nestopia damn near identical.
• Latest Sunsoft 5B mapper with Gimmick! on the EDN8 compared with Nestopia, more or less identical.
• Latest VRC7 mapper compared between EDN8 and Nestopia, 2A03 channels sound significantly hotter on the AV Famicom with the EDN8 than in Nestopia. Can really tell with the PCM kick & snare drums, they pop out a hell of a lot more on the AV Famicom than in Nestopia.

I'm being incredibly nitpicky here, but those are my findings.

WHAAAAT

Trying this on my AV Fami right away.

UPDATE: the FM Synth channels sound quite accurate, except for their volume level in relation to the built-in Famicom sound channels. The FM Synth channels sound way too quiet. Other than that though, it's well on its way to being an amazing addition to the Everdrive N8. Awesome work!

My RGB-modded AV Famicom with the SmokeMonster set used to have this issue, especially when playing certain games; Gargoyle's Quest 2 comes to mind, but after a recent update it seems to have gone away.

EverDrive N8 / Re: Best console for NTSC N8
« on: March 30, 2017, 08:30 AM »
My humble opinion: AV Famicom with the famicom version EDN8. You get the expansion audio stuff without having to mod it.

You may want to get it modded with NESRGB and get a Framemeister or OSSC if you're planning on using it with a modern TV though.

Orrrrr you could skip all that and get an Analogue NT Mini. Then you wouldn't even need the Everdrive.

Yup, FDSStick is the way to go, no telling when/if the N8 will ever have working FDS audio IMO.

Honestly, how many more sales of the Analogue NT will happen just because it's the only hardware you can play the English-translated Lagrange Point on when in conjunction with an EDN8 and the patched ROM? If you ask me, I find the withholding of the VRC7 audio code to be quite petty. But it's Kevtris and Analogue's prerogative to do it, so.. welp.

So, since the code to simulate the Lagrange Point audio hardware on a FPGA already exists on the HiDefNES thanks to Kevtris, wouldn't it be possible to just use his code for the EDN8?

I get this like crazy on my NESRGB modded AV Famicom with the EDN8, but only on certain games. The game that stands out the most is Gargoyle's Quest 2. This is both on my PVM and my Framemeister.

« on: June 26, 2016, 11:43 AM »
Best way to cross check this is by running the same rom through retroarch with the Nestopia UE core. The weirdness I noticed in SMB3 on my AV Famicom with Everdrive N8 was also there when emulating the ROM, so it was part of the game. Lots of NES games have weird glitchy looking things in them.

Yup, I have a NESRGB modded AV Famicom with the Famicom Everdrive N8 and I play mostly North American NTSC titles on it.

EverDrive N8 / Re: Individual N8 Mapper Updates (unofficial)...

By demand i added more volumes to my mapper. Here is a graphical summary of all currently available versions:



Download it here. https://sites.google.com/site/slamyselectronicslab/24VRC6ModXtra.zip?attredirects=0&d=1
Any idea which one I should be using with my AV Famicom for the best sound mix?

EDIT: finally found the right answer and that's the 75_70 one. What a huge improvement from the stock mapper. Thanks, Slamy!

The PCM still sounds really dull unfortunately, but the VRC6 synth channels sound much closer to the way they're supposed to. I can actually play Akumajo Densetsu without getting furious at the terrible sound mix now.
