Title: SD2SNES June 2016 re-stock PCB revision?
Post by: Brachabre on June 14, 2016, 09:26 PM
This question is probably more directed toward Krikzz or Ikari. Are the re-stocked PCBs in Krikzz' store rev. F or G? Thanks!

http://www.zeldix.net/t1195-correct-msu-1-volume-levels

I was reading the Zeldix forum and apparently Rev G allows the board to utilize 5v instead of 3.5v which supposedly helps with the MSU-1 feature's volume level problem ie apparently there's uneven audio at times when using this feature and too quiet audio which apparently getting to utilize 5v of electricity may somehow fix.

Have no clue what any Rev H may be about though, but if I had to wager a guess maybe its yet another improvement for the MSU-1 feature?  :P

Unless you're way into MSU-1, the revisions aren't that important.

MSU-1 is literally the only reason I am considering the SD2SNES. What should we be aware of with regards to MSU-1 and the revisions?

From ikari

The difference from Rev.F is that the DAC runs at 5V to improve on the MSU1 volume issue. See also http://forums.nesdev.com/viewtopic.php?p=155367#p155367
Rev.G is otherwise identical in capabilities and compatibility as no core hardware has been altered.

And here is someone doing the G mod to their F board

I've done the mod on my rev. F. Here are some pictures.

All the G board does is boost the volume on the MSU-1 audio. Nothing major imho.

Rev.H then adds an op-amp to finally bring the volume up to bsnes level. It also switches the DAC back to 3.3V because there have been some noise issues with 5V.

Thanks for the Rev.H info ikari_01 :)
Is there any update on modding earlier revisions into a Rev.H?
It would be great if a small add-on op-amp upgrade PCB could be developed.

Still working on the instructions... my PC broke last week so I spent the weekend putting it back together. I'm in the process of editing the photos for the instructions. Fortunately you can use existing pads on the sd2snes PCB to solder part of the opamp to so at least it won't be dangling from a bunch of wires.

Thanks ikari, sorry to hear about your PC :-\

I'm glad to hear the op-amp wont need to dangle from wires!
Will you be posting the info here, or on your blog?

While I continue to suck at authoring (and recover from Christmas):

The opamp is a TS922 in SOIC 8 package.
Also you need two 10 ohm resistors (SMD 0805).

Pics are done, if you're curious see https://sd2snes.de/files/RevH/
00_orig-RevG_mod.jpg is only needed for original Rev.G units to bring back the DAC to 3.3V.

Okay, I'm done with it... made it on a Rev. F that I upgraded last year to Rev. G and now downgraded it to Rev. F again to upgrade it to Rev. H :o The soldering on that chip in pic 11 is a pain in the ass!

Here are two pictures of the upgrade to Rev. H:

(http://fs5.directupload.net/images/170102/temp/vabbl2xi.jpg) (http://www.directupload.net/file/d/4588/vabbl2xi_jpg.htm)  (http://fs5.directupload.net/images/170102/temp/g479d3sl.jpg) (http://www.directupload.net/file/d/4588/g479d3sl_jpg.htm)

I think the way ikari showed is simple and works as it should, but I have like 1000 pieces of the Soic8 boards so I just used one of them.

Thanks again ikari!

Wow! What this mean, a pre-assembled PCB to do the upgrade from Rev. F to H? Sorry the newbie question, but how this works? This eliminate the need of all the soldering to just one or two? I definitively need to learn the basics of analog eletronics =/
Title: Re: SD2SNES June 2016 re-stock PCB revision?
Post by: borti4938 on January 23, 2017, 10:29 AM
The board is designed in such a way that you have to remove the SMD components (see this picture (https://sd2snes.de/files/RevH/02_remove-smd_short-gnd.jpg)) and place the PCB directly on the the freed pads. Last step will be then to solder the Rev.H ID wire (see here (https://sd2snes.de/files/RevH/11_hwid.jpg)).

The PCB was shipped last week - can't wait to test it :D

Could C1 be retrieve from one of the caps to remove (like C347/C348 for example), or there are no capacitor with the right value and do I have to order a 0.1uF capacitor ?

Resistors and capacitor are ok, but the op-amp must be in a SOIC-8 package. Yours is a TSSOP-8.
I think this one should be fine:

If your sd2snes was/is Rev. G, please consider that:

Important: There is one additional step for original Rev.G sd2snes which he didn't account for. You need to remove FB341, turn it 90°, and solder one end back on to the LEFT pad. Then you connect 3.3V to its "floating" end. On your sd2snes, the patch wire for 3.3V is already present, so you can use that one. Or you can use another solder point. This is how I did it: https://sd2snes.de/files/RevH/00_orig-RevG_mod.jpg

Until a couple days ago, I knew there had been revisions to the SD2SNES, but since it wasn't preventing me from enjoying games or updating the OS, I hadn't paid much attention. My SD2SNES is Rev. E1, I bought it in 2013. Besides the audio issues with MSU-1, am I missing anything? I'm giving some thought to upgrading and thanks much for the above post and this thread for the needed info ... but again, besides the MSU-1 issue, am I missing anything? Does the problem with older revisions affect all audio output, or only the MSU-1 output? Is there any in-game performance or compatibility that the upgrades from Rev. F and then to Rev. H would affect (not including MSU-1)???   

I ask because I think the MSU-1 feature is great, but I don't really use it much. I don't know if I want to perform these operations on my SD2SNES just for audio improvements I'll rarely notice.

My understanding is that it's only for MSU-1 stuff.  That's why I haven't done the mod on mine; no sense risking borking a $200 device for a feature I rarely use.

Exactly. I mean, I think I could handle it. I've done S-vid and RGB mods on my Super Fami Jr., RGB mod on my N64, installed a XenoGC in my Gamecube, etc. But if this doesn't have any effect on regular game audio, then I'm not concerned.

I have a Rev H but I recently got a Rev E1b for my nephew's Christmas present. After adding the capacitor and ferrite bead to update to Rev F, I went ahead and prepped three of Borti's boards, installing one. It didn't work. Audio was almost inaudible, even with boosted MSU audio enabled.

It was very tough to remove without hot air but I managed and installed a second board. No change. I'm confident that both boards were assembled correctly and, yes, the chip was oriented correctly. The same ROM from the same SD card works fine on my original Rev H. Actually, it seems a bit TOO loud but that may be the specific ROM. It says "MSU old" in the file structure; is that boosted? Either way, if the mod was successful it should sound the same on both, but it doesn't. I checked all connections with a continuity meter. Everything is connected, nothing is shorted.

Does this mean I have a clone on my hands?

I noticed JP401 was shorted on Borti's instructions but he didn't mention it and that seems to be a 0-ohm jumper on mine anyway.

I shorted JP341 per the Rev E1b advice in this thread (same place as FB342) though it seemed to be a 0 ohm jumper resistor in the first place. My original Rev H has a zero ohm resistor there even though it's labeled as a ferrite bead/inductor (FB342).

Did you test MSU audio on the E1b before doing the Rev.H mod? It should be sort of quiet, but well audible.
After doing the mod, it should be exactly as loud as a "stock" Rev.H.
Another thing to check is whether FB341 is conductive (it should be). It is responsible for the power supply of the DAC and op-amp. You should get around 3.3V on the left end terminal of FB341.
Does it get hot?

If it doesn't you may short it out with a solder blob or piece of wire for testing. It won't do any damage but you might get some more audible interference from the digital domain.

If FB341 does get hot there is probably some short circuit in the DAC/opamp area.

Thanks. I'm checking the same things on both to note discrepancies. So far, both show continuity across FB341. Both measure nearly 3v between the left side and ground (a little lower). Neither feel hot.

Unfortunately, I did not test MSU-1 audio first. I didn't have the SD card handy from my other SD2SNES and I knew that the MSU-1 audio was less than ideal on E1b so I didn't bother to load any onto the SD card during my original testing. I ordered the stuff for the mod thinking I had plenty of time before Christmas to fully test and mod, but then my brother (nephew's father) paid a surprise visit from several states away. This pressured me to finish while he was still visiting so that I could avoid the need to ship the gift to my nephew. As a result, I was removing components while an MSU-1 pack was still downloading/extracting on my computer. Everything else worked so I assumed MSU-1 was working as well as any other E1b. Really regret that assumption now since it's pretty darn relevant!

MSU-1 sounds extremely quiet, but audible after completing the mod. I've never heard the lower volume of earlier revisions but I imagine that they would have to be louder than this. I have to crank the volume to even tell that there is music playing and by that point the sound effects are ear-piercing. I'm pretty sure now that "Old" MSU files are already boosted so it would be nearly (if not completely) inaudible at a proper volume for the sound effects if the MSU-1 files weren't already boosted. Because RetroRGB said he had no MSU-1 audio with his clone, I wonder if we are both looking at clones? The vias do look like they are made slightly different. My Rev H was purchased from Krikzz here but the E1b was used from someone on NintendoAge. The previous owner paid for a Stone Age Gamer label to put on his modified SFC shell so I assumed he bought it PCB-only from SAG.

Should I restore it to Rev F to do more testing? What are the values of the components I removed? Doubt I can dig them out of my solder blobs. :)

Good news! More than 24 hours later, it works for no good reason. :)

I'm pretty sure it was just 99.9% pure electronics cleaning grade alcohol hiding under one of the chips or something. Though the pics show that I obviously didn't clean back up after installing the second board (was still troubleshooting), I recall loading my swab with isopropyl the first time and having a bit more get on the board directly from my dispenser. The puddle was right where I wanted it anyway though obviously a bit more than I intended to use. I figured it was just going to dilute the flux even more and quickly dried it off. Of course, there was no alcohol remaining on/under the mod board after desoldering and adding another so it had to be hiding out somewhere else too.

To get it working I simply heated the board with a heat gun on a low setting from both sides, waited for it to cool, and it works flawlessly now. Now I'm scared to clean up my flux!

If anyone wants to to update to Rev H, I fully assembled the other two of Borti's mod boards and I'm offering them on eBay for about what it cost me. I can also include the inductor and capacitor for updating Rev E to F. Heck, I can even install it for you if you want to send the board or meet locally (Atlanta OTP South region).

Hi everyone.

I see that most everyone in the thread knows what they're talking about. I have no clue of any of it since I'm not technically skilled in electronics.

I bought the borti board today,  as I'm planning to take it to a local technician to install it,  I'm upgrading from revF to H,  but I need 2 things in order to do this:

1. does anyone have a noob guide,  where its detailed step by step how to install the board?

2. Do I need to buy anything else at console5.com in order to install the board correctly?

Thank you in advance.

LOL, so you buy a 200$ cart and not use it's main feature of msu1 audio? buy a super everdrive and its the same result..
