SNES RGB Bypass + Dejitter: Two Mods, One Board!

[Arthrimus]

So today the first batch of production pcbs arrived from the board house and they look great. Unfortunately they messed up the order and produced them on 1.6mm substrate instead of the intended 0.8mm substrate. As a result of this mistake the boards from this batch will be more difficult to solder, specifically the multi AV pins because they are not long enough to clear the thickness of a 1.6mm board. I have decided not to place them in stock at this time because of this. I put in an order to have the boards produced in the correct thickness and I am hoping to have the new boards in on Friday or Saturday. If you really want one now, these thick boards do work just fine if you can deal with soldering the recessed AV pins. PM me if you want one now, otherwise just wait until I put the corrected boards in stock on the website.



Speaking of my website, it's been offline for most of the day due to issues with my web host. They are working on it but at the moment I don't know when it will be fixed. If the site isn't back online soon just PM me here on the forum if you want to purchase a board.

In other news I had a chance to install one of these boards on a CPU-1CHIP-01 with great results. I have a video of the installation on my youtube channel.

Awesome work! I missed ordering the few you had in stock. Looking forward to you getting some more in and ordering ASAP. Looks like the perfect one-stop mod for my 1-chip-03! Thanks for doing this!

Thanks!

Hate to bump my own thread like this but I just wanted to let everyone know that the new batch of PCBs arrived today so this mod is officially in stock at my store for anyone who wants a pre-assembled board or installation service.

Gotta say, this is a good price for the kind of work this project required.
I like it

Ordered as soon as I saw this in the morning!

do you need to use the coax, and what coax are you using there? I see that you use it in the install video as well. TIA!

[Arthrimus]

You don't have to use coax, but I recommend it simply to cut down on potential interference or stability issues. I've never personally experienced any problems using unshielded wire for clock, but it doesn't hurt to be safe.

The coax that I use is actually just shielded audio cable that I harvest from old composite AV cables.

Right on, well I have plenty of that! Thanks! I'm hoping to get it installed on my 1-CHIP03 this weekend.

Good stuff here.
thx for creating it.

Hello. Thanks for making this. I decided to try and build my own but I cant get it to program. Is there anything different about how this is programmed vs the regular de-jitter board?
Using OpenOCD I am getting...

Hoping I haven't made a mistake somewhere. I can follow instructions but actually understanding any of this is beyond me.

No, it programs exactly the same as the stock dejitter board. Are you using a raspberry pi to program it? If so you will not get very reliable results. You'll need to have your programming wires as short as possible then it still won't work 9 times out of 10. The easiest way to get it programming reliability is to buy an FT232H breakout board from adafruit and install libusbk drivers. It will program successfully every time.

Thanks for the reply. I am using a raspberry pi and the wires are very long ~10"
I will try with shorter wires, if that doesnt work I'll try the device you suggested.
I do have one of those clone altera blasters (ebay, filter lowest + P&P)... is that any use if the pi wont work?

Is this the FT232H breakout board you are referring to? https://www.adafruit.com/product/2264

Do you still use OpenOCD to program the code? Could you show your setup and perhaps an instruction how you did it?

[Chris230291]

I made no progress with the Pi or the blaster. Just lots of openocd errors.
Decided to buy one of those adafruit FT232H boards.
Could you share the config required to get it working please?
I installed openocd from the default raspbian repositories (apt install openocd)

Thanks,

what was the issue with the altera blaster? those are meant to be supported 100% by openOCD

I may have missed it in the thread, but pretty sure not.

Does your board incorporate the attenuation / brightness fix?
I didn't see any mention in the thread or anywhere else I could find mentioning that this was included on the board.

I know you did say the RGB portion is electrically identical to Borti's RGB mod, but the past few versions of that look to have lost those resisters (while keeping the pads) and a warning to use only those OR the external resisters at the RGB vias. Looking at the layout of your board, it looks like there are more resisters in play compared to the shipping Borti board, but the resister values don't match the typical recommended ratings for brightness correction.

If everything I say is correct, what happens if someone were to double up on the resisters like that(using the ones included with your board and adding the others)?

R16,R26,R36
and
R17,R27,R37

Are the pads I'm confused about.

If anything, I guess I'm asking to help me learn a little?

So I always wanted a SNES JR because its a 1chip. I bought a pre-modded JR off ebay and the seller exclusively uses your dejitter board. He says its the best but I am the first person to encounter many problems. I plug it into any CRT and the colors for S-Video are 100% wrong. I plug it into my GV-USB2, arguably the best capture card ever for SNES and the colors are wrong. I plug it into my Sony Bravia LCD with S-Video and it looks magnificent. Do you have any idea why its so problematic to get this working on an actual CRT and not an LCD?

[RastaJedi]

So I've been trying to program this board for over 12 hours. That is not an exaggeration. I have tried OpenOCD/UrJTAG/Quartus with USB Blaster clone and the new xFlasher. I have verified continuity between the TMS/TCK/TDI pins and their respective pins on the CPLD. I have verified TDO goes to the two resistors, one has the other side to GND, the other is going straight to the CPLD leg. OpenOCD gives me this issue (with all 3 drivers provided by Zadig):

Code: Select all

tdo check error at line 21
    READ = 0xffffffff
    WANT = 0x150203f
    MASK = 0xffffffff
fail to run command at line 711
tdo check error at line 21
    READ = 0xffffffff
    WANT = 0x150203f
    MASK = 0xffffffff
Time used: 0m6s327ms
svf file programmed failed

I have verified countless times all the JTAG pins are wired correctly to the Blaster's pins. I have used the Blaster earlier today to program Borti's N64Adv mode successfully. ATMISP won't even recognize the chip. I have provided +5v and GND to the respective pads for the multi-out, providing external power, and the JTAG header's 5v pad is correctly wired to Vcc(TRGT) of the Blaster. I am at a loss. I have been trying this for SO long it's not even funny. I have even tried compiling OpenOCD with Samson7point1's change where he commented out the latency checking part.

Please, can someone help? I know what you guys are going to say: "get a FT232H breakout", and I actually am already planning on that, but this SHOULD work, and I want to know how to make it work, because a) I gotta ship this board out to customer ASAP but more importantly b) I want to know I can successfully program things with a Blaster clone!

[RastaJedi]

I'm getting terrible jailbars with my Retro Access coax csync SNES cable after performing this mod. I redid it to move the lines further away. HD Retrovision SNES cable looks absolutely fine. My csync cable looked absolutely fine before this mod. RetroTINK-5X's LPF is set to "light", and the THS7374's LPF is off.

What do I do? Same thing happened to my friend. He wired up LLCS, and an Insurrection Industries luma cable looks fine but a RGC csync cable looks bad for him too. He also has an weird vertical line even with the luma cable.. I've no idea what that is, but the jailbars, we both experience bad. Our installs are similar.

Any tips?

[8bitForLife]

probably sounds stupid but how do i use the bom ods file

[RastaJedi]

Lol, it's a OpenOffice.Org file. Import it with Google Drive. But I want you to be aware, before you spend money on this project, it seems to induce terrible jailbars (unless you want to have very strong LPF and lose sharpness), likely due to the fact the clock signal is a very long run and its pad is directly next to the RGBS pads. I experimented with different types of wire, including coax, and several of us have not been able to fix the issue. I'm not sure if it can be fixed. If anyone has some tips, please let me know ASAP. I was going to try adding a resistor to the clock line but I was so disappointed in this whole endeavor that I just put the SNES away indefinitely--I don't even want to look at it right now.

As far as I know, no, it does not incorporate brightness fix. You may be confusing where Borti's documentation mention not doubling up on the decoupling caps, and you don't want to do that. If you double up on a brightness fix, you'll end up with a darker, out-of-spec image.

This is a BOM I made based on the original for this project, you're welcome to look at it and also this goes for the previous reply too, @8bitForLife https://docs.google.com/spreadsheets/d/ ... p=drivesdk
