Title: SD2SNES (last revision of the board)
Post by: den1976 on June 09, 2014, 05:13 PM
SD2SNES

tell me the differences between audit fees (rev e1, rev e2, etc.) ?

which at the moment is the latest revision of the board and which board is better to buy and why?

rev 1(MK1) was the prototype, not made into production. Rev 2 (MK 2) is the one current one that's being produced.

KRIKzz already answered him here
http://krikzz.com/forum/index.php?topic=1776.msg17746#msg17746
and that the version of E1b, C?

SD2SNES what version is currently the final?

and what version SD2SNES boards have for sale at the moment on stuffpoint.ru?
Unlike the Everdrive series is different in each new (re)version including OS software.

Sd2snes E1 and E2 series are virtually same except for components (chips) were used as KRIKzz stated.

You need to contact stuffpoint.ru, ask them which version they're selling.

 SD2 Snes

please throw off the entire folder with firmware version 0.1.6 (with dumps special chips) you want to throw on a memory card ( the entire folder with all the directories that are needed to complete the work  SD2 Snes (everything except the games)

OK. Anyway probably the only differences is still just alternative parts when older parts are phased out or gets harder to get. No new functions or anything.

rev. F ^^

Interesting. Ikari stated on his blog that the hardware is final quite a while ago (at least since krikzz started manufacturing them, I think). Any idea what the differences are from revision E boards? Or is it just updated because parts used on revision E aren't being made anymore? I think he also said that would be the only reason board revisions would be made now...

Well that answers that.

OK Ikari did say "Hardware upgrades might happen if any “physical” problems become known or some end-of-life parts have to be replaced.".

If you always want the latest version you would have to keep buying new SD2SNES carts all the time! And if you don't make one yourself, there's really no way to know how long the one you buy have been laying on the shelf. Ikari said "the capabilites of the hardware will remain the same." so he will probably not make new features that only works on the latest revision.
Title: Re: SD2SNES (last revision of the board)
Post by: ZeroWing on June 19, 2014, 04:27 PM
"Hardware incarnations? None. The hardware is final as it is. Minor changes are done to account for parts going out of production. These are not affecting the capabilites of the sd2snes though. What the hardware can’t (theoretically) do now it can never do." This is a quote from Ikari. The fact that it came directly from his fingertips makes me feel that it does not matter what revision card you have, so really there is no "best" revision.

Post by: ikari_01 on June 23, 2014, 11:17 AM
What ZeroWing says.

Rev.E1: the version made by KRIKzz up to now.
Rev.E2: actually older than Rev.E1 - I made E2 because the voltage regulator I used became unavailable to me, so I replaced it with parts. KRIKzz can still source the original regulator so this change was irrelevant to him.
Rev.F: A very recent revision. I just sent the CAD data to KRIKzz. This revision accounts for issues that some people with "1CHIP" consoles have been facing. There was an RF-like interference pattern to be seen on screen in some occasions. It is based on Rev.E1.

Feature-wise all revisions are still identical.

Hey Ikari,
I have SD2SNES on its way and a 1CHIP snes. Can you give me more info about this issue so that I'll know what to look for? Thanks.

You are looking for some kind of irregular "wind" pattern in the picture, a bit like bad TV reception (back when it was analog ;))
Like this but FAR less pronounced. It is barely visible, if at all. http://www.avforums.com/attachments/051130_091446-jpg.21520/

Being a 1CHIP user this interests me , is there a way to mod a SD2SNES from KRIKzz's 2nd batch (bought at 07/05/2012) and fix this interference?
Not that I have noticed anything but if it's easy why not?  ;D

I'm also interested in that kind of a mod.

If such a mod is not possible:
When will it be sold on retrogate.com?

Post by: ikari_01 on June 26, 2014, 05:21 PM
It's easy to mod but you lose your warranty I guess ;) Just 2 small parts need to be added.

The following pictures already show the new revision but it should become clear what exactly the modifications are.

(http://sd2snes.de/files/RevF/sd2snesf_top_detail.png)

The capacitor ("C391") goes to +5V and GND near the +5V pin on the slot, on the IC side of the board. Just scrape off some of the solder mask and solder it on.



(http://sd2snes.de/files/RevF/sd2snesf_bottom_flipped_detail.png)

The inductor ("L391") goes to the opposite side of the board, into the supply line. You need to cut the +5V trace coming from the same slot pin as before, again scrape off some solder mask on either side, and solder the inductor on.
Title: Re: SD2SNES (last revision of the board)
Post by: keropi on June 27, 2014, 12:04 AM
thanks ikari_01 for the info! it's easy to do  8)
I do have a question though about the inductor installation, you mention that "You need to cut the +5V trace coming from the same slot pin as before" , do you mean I need to cut a trace or just scrap off the solder mask so I can solder?


edit: also will the following components be OK? I can't source them locally so it's eBay for me...  :-X

Title: Re: SD2SNES (last revision of the board)
Post by: ikari_01 on June 27, 2014, 12:21 AM
Ah yeah that sentence was a bit bogus...  ::)
In the green picture you see L391 which is the inductor you need to place. On your sd2snes you just have a copper trace instead of the inductor. That trace is "interrupted" by the solder pads for the inductor in Rev.F and you need to do the same. Cut the trace there, scrap away on either side of the cut, and put the inductor.
The parts you listed are ok. The capacitor is 1210 instead of 1206 (a bit bigger package) but it doesn't matter much.

I've no doubt that I will lose any warranty as my sd2snes is one of 'yours' 8)

I can't say for sure. TSR tested on several differend 1CHIPs if I remember correctly and saw it on every one of them. I didn't see it until I connected it to a professional CRT. So it might even be a combination of console and display.

Out of curiousity, when are the Rev-F changes going to be pushed to Github? I can only see the two REV-E boards right now.

Additionally, U501, the PSRAM is... really difficult to source. Beyond obsolete. Do you think it'd be reasonable to swap it for 2X IS66WVE4M16ECLL-70BLI ? They're coming into production *now* so they'll be available for a while... and there's even a TSOP version planned.

By the way... great work! I am going to build up a handful.

I just performed the cap, inductor, and wire mod on my E1b, bringing it up to an effective Rev G.  Works beautifully for me.  BE CAREFUL cutting the trace; I accidentally sliced one of the thin traces above when my blade slipped, and I had to repair it.  Cut DOWN AND AWAY FROM THEM.
