Definitely!RGB32E wrote:This is where you use a liquid flux pen...
I considered it, but it would have involved having to add a mux to select between the onboard oscillator and the master clock coming from the SNES. I figured adding it would have complicated the PCB layout quite a bit, and I wasn't going to use the feature personally, so I decided to leave it out.RGB32E wrote:Have you considered adding a SRC bypass option?
Lol, as RGB32E said, use flux. A lot of flux. You also have to be a bit strategic in the order in which you stuff the parts. For example, solder X1 before R5 and R6 otherwise you won't have much room to solder the bottom 2 pads on the oscillator. Also solder U4 before C1 and C2, and solder FB3 and FB4 before FB1 and FB2. Pay attention to part orientation, and above all else take your time. It's a tedious build.CkRtech wrote:<Gets information from L-Train and orders parts>

Ha. Yeah, it is. I knew that going in, but I was just having a bit of fun with my image. I have drag soldered stuff like this before, and I generally work the most complex stuff first (pin packages) & then go from the inside out across the PCB. That said, the solder work and continuity check definitely requires the usual amount of patience when doing electronics - it'll just take a little bit longer this time.L-Train wrote:It's a tedious build.
Very cool! Looks like an attached TOSLINK transmitter? It doesn't look like the connector has a hole for mounting though? What's the P/N of the transmitter?retrorgb wrote:PM me if anyone's interested in buying the leftover (fully working) prototypes.
Right, the optical audio port is directly attached. I've been mounting them simply by cutting a square hole in the back of a SNES Mini, or removing the RF module in a SNES1 and using it's hole. Then I just glue it in. I use basic hot glue on my personal one, just because I know I'll probably have to take it out for one reason or another, but that's kind of a fragile (and ugly) solution. I did a few others and used epoxy. That worked perfect and you only need a tiny bit of epoxy, so it's barely even noticeable from the inside (either solution looks fine from the outside).RGB32E wrote:Very cool!

Considering this mod has been around for YEARS, your exuberance is entertaining at best, given the fact that the SPDIF mod was already awesome...austin532 wrote:Stop it FBX, you are making retro gaming become too awesome![]()
Yeah, no kidding. Built and installed the CS8406 circuit 6+ years ago in my 1CHIP-01 and haven't looked back! Coincidentally, the extra SNES I had picked up for $20 to perform the mod on was how I discovered the 1CHIP-01, and it's nice RGB output.CkRtech wrote:Ha. Wow. <raises cane and shakes it> Back in my day, we had to wire the mod completely from scratch!![]()
Good stuff. Check out the bass response on Space Megaforce/Super Aleste. Especially good if you have a subwoofer.
Well, that's completely contrary to my results and others, not to mention a head scratchingly vague account. If anything, nuances of a given mix are much more clearly defined and not obscured!FBX wrote:I looked into the MegaAmp with side-by-side tests and I ultimately decided it wasn't for me.
Here is the connection to the uncompressed sound record. The break out link to my sound card that can record s/pdif is missing so here is the manner by which I recorded this.L-Train wrote:The N64 is something I had in the back of my mind when I was designing the circuit, but since I don't have an N64 I couldn't test it out. The SNES S/PDIF board is configured to only accept 16-bit right-justified audio, and thankfully the N64 RCP outputs that same format (according to the datasheet of the N64's audio DAC, the BU9480F) so it might actually work! The only thing I'm unsure of is where to connect the /RST line as I haven't found a pin diagram for the RCP. Perhaps just tying /RST to 5V would suffice, though.RGB32E wrote:User "L-Train" released his up-sampling SNES SPDIF circuit on OSH Park a couple of weeks ago.

Looks slick. I'll share my results when I get this assembled and installed! I wonder if this circuit can be tailored for the N64 since this circuit contains a sample rate convertor for up-sampling.
Anything specific to set this up? I got this one from amazon and it doesn't even seem to detect the 32khz coming out of my snes.FBX wrote: https://www.amazon.com/VAlinks%C2%AE-Ch ... +6+channel
It's the perfect cheap solution for getting TOSLINK audio into your PC. I needed it because I fried the TOSLINK on my internal sound card trying to capture PS3 audio as it switched to PS1 mode.
Be warned though, some recording programs will capture the audio at a sped up 44.1 Khz, but the simple fix is to change the file's playback rate to 32Khz and it corrects the speed.
