Hi guys,

So I had sent a few tickets to support about the error 91 , SDR issue and I thought why don't I fix myself (risk the warranty) , after speaking to support I came to conclusion the ram is faulty and almost sent to krikzz for repair, when I realised I had some issi 6ns 54-tssop ram sitting around.... OH the dilema, I've never removed ram  as I don't own a hot air station and wondered if I could get away with it using low melting point solder ? YEP it was easy-mode. I put a line of low melting point solder enough to cover all pins left/right of the 54-tssop and proceeded to heat both sides up wet and wow it flew off after a little time.

Now the moment of truth I put new ram on again with a 35 watt 10$ iron I can't afford these ' temperature controlled soldering stations' anyway and to be honest I've never required one for SMD work... so whatever the new ISSI ram is on.



Does she boot?



Does she play?



Hopefully that damn error 91 SDR will stop plaguing me, I thought I'd sorted it a few times thinking I had fixed it by setting it to 25mhz spi as appose to 50mhz, and even trying to find dry joints.. but no the issue is random to say the least.

I'm one happy ED64 owner and I won't let this take away from what is 1) great firmware, 2) great hardware, and 3) great support. I understand that some problems occur with hardware that is out of the manufacturer/designers hands at the time because let's face it - it took weeks  to show it's true colors, different humidity/ temperature etc can surface the issue - faulty ram is hard to diagnose especially if it's tssop where it is unlikely to have been burned in by  krikzz which would take a long time to do.

Enjoying my ed64 v3.

Dear all.

I had a error 91 SDR issue and krikzz was kind to offer to fix it , i was going to send it to him to fix because i didn't want to void my warranty, however I grew some man balls and just re-flowed the ram and fpga (closest to ram) and resolved the problem. Yes it was simple as throwing some fresh solder bridging the entire ram both sides and then with a hand pump removing excess followed by liquid flux RF800 Topnik using a cheap 35 watt iron, the trick is to not stay in the same place and keep moving back and forth removing excess with side-strokes. Now Zelda and all the games work as normal - off I go :) WOOHOO!

Edit: I replaced the ram with  54-tssop 64mb ISSI ram as the problem kept coming back... Certainly bad ram but it's the only solution.

Great news  :)

I'm also curious about the meaning of this code, I've seen it before but forgot to ask about it...

Thank you! and yeah I was confused at first because when I tried the latest firmware all I got was a black screen... 1.6 to later i got that long code in white text in a black screen and assumed I'd fudged something up, was it a missing bios? I wasn't sure, and kept powering off the device (if that was a firmware flash perhaps I ran the risk of bricking it doing that?) regardless it worked out after I patiently left it ... phew! :) 

The only game I have run into trouble so far is magical pop'n JAPAN en translated. it appears that ingame hooks get in the way of the magic select + use of magic... it's no big deal though fixed by disabling them but I'd love to see a per game setting either hardcoded .xml for sake of a quick patch next round or UI options per game... not as important though.

Regardless the device works as described and I look forward to 1.8/1.9 firmwares for the FGPA chip.

I've had my  H for a week now, it's my first sd2snes, after enjoying Everdrive GBA for month or so on a 101 gba I thought I'd venture down the Snes/super famicom path and I wasn't disappointed. I ordered mine from Retrotowers (they were kind enough to ensure I got a H and it arrived in a few days!) .

I had problems installing 0.1.7e firmware for some weird reason so installed 0.1.6 and went up from there, i noticed a long-code on the screen which resembled some kind of identity code and thought i'd best leave it to do it's thing to my surprise it had upgraded the firmware and I was  rocking 0.1.7e.

I have been told by krikzz via e-mail support that NTSC consoles are more favorable choice so ordered a 1-chip japanese super famicom from ebay (s/n database and 2-3 days of scouring ). got one for about 50$ inc shipping! YAY... it's arrived in the UK and will be at my doorstep soon... in the meantime I've been playing on a PAL snes I sourced last week for PAL only games to run at 50hz... while NTSC-J console will be suffice for the NTSC USA and NTSC-J english translated. (Tested a few but I'm sure they're not running at the correct framerate on PAL).

Overall really happy with shipping time, product quality, ease of setup.

Would love to see the fx chip and sa-1 supported in the near future but appreciate the level of work that will go into that and therefor can be patient :)

Thank you for a great product Ikari and Krikzz for both the level of hard work, research, commitment to the scene and the manufacturing process, including future support of the products and your general love and interest in putting this kind of power in the hands of retro enthusiasts such as myself.

I have no regrets and every game thrown at it works a charm! and my girlfriend enjoys it too so yeah you've done well :P  we almost completed captain commando together today! ALMOST!

For those of you in the UK - I grabbed a H from retrotowers.co.uk in 1-2 days shipping time, I had to make sure first by calling them but was pleased to grab a H revision since modding small pcb's isn't something I'd want to risk with 190$ cart avoiding e/g/f for that reason .

I personally went for a NTSC-Super famicom 1-chip (02 i think based on serial number) with a PAL/NTSC-J shape sd2snes cart H from retrotowers.co.uk (Krikzz told me NTSC console was the best option over PAL via support email) probably due to the fact there are more NTSC US + JAP NTSC-J in EN translation will run at 100% proper speed on a NTSC-J console then that of a PAL console (20% difference in speed? regarding 50hz from 60hz frame drop).  Waiting for jap console to arrive but meanwhile been testing on PAL super nintendo on NTSC games and it's likely I'm not getting the full speed of them games although for few european PAL only games I'll be keeping this console around. Pros: NTSC-J Super famicom seems like the best option overall for not only cost and a rare and unique opportunity to fetch a 1-chip for less than 50-60$, NTSC-J games running at proper speed! and no requirement to mod the console either. The cons is delivery from japan can take 2-3 weeks or more. But that's worth it right? :P

How about you simply solder into the screw very carefully with screwdriver tip to create a nice place for unscrew and then after replace screw? just an idea... alternatively i bend the edges so i can push along it with screwdriver, worked for me on a laptop small screw which was stuck .
