Little update.
At the moment I've solved the automatic run of the script on boot by adding: After creating a new user-startup.sh file on /media/fat/linux.

Now I need to test if using the script I'll have the same issue but at least it seems to run properli on boot now

I might have found at least one of the issues the S99spin script in /etc/init.d doesn't star when mister is booting, if I manually start the spin script at least is reported to run when I check with ps -ef | grep "Spin" command. I did'nt test enough the misteer with the script running but it's been like 30 minutes that I'm running some PC...

Thank you for your answer, I've tried following your suggestion but after a while the error occurred again, I'll try to lower the interval. The only odd thin is that I have a very short UUID on both the HDDs I've tried (I connected only once a time with same files when I tried to play): /root# blkid /dev/loop0: UUID="1ee65149-762a-43be-9c95-93...

Hello, I'm using this 2TB hdd for quite a while to store the games for mister : (https://www.westerndigital.com/products/portable-drives/wd-elements-portable-usb-3-0-hdd#WDBU6Y0020BBK-WESN). This HDD made some strange metallic sounds from the beginning but only when used with mister (tried 2 hdds of the same model) but didn't give me any particular...

just tried with 2 6 buttons arcade stick and it works perfectly!!

Thank you very much for the instructions! I was able to program both ports and now seems to work flawlessy!!! I say "seems" because at the moment I can try only with a 4 button arcade stick, I'll go to take the 6 buttons later and report here!

I was looking at the GitHub what do I need to use to program the board with the new firmware? Something like Arduino IDE?

Thank you very much for the efforts!! I won't be at home untill tomorrow but it's the first thing I'll try! I'll report here as soon as I can!

Schematics attached. I don't know if it's better to start a new topc or not, I was able to design the board with a friend and yesterday I assemblet it, unfortunately is not working. I've tested with a SNES pad test rom and those are the results: - If I insert the adapter (tried with 2 of them) Start + B buttos are pressed and stay pressed even if ...

Hello, I've been able to assemble SNAC (USB version) and all the controller adapter, everything is working but there are a couple of things that are unclear and I wasn't able to find an answer on the web. 1) The JST X1 connector (not the jumper) on the SNAC PBC what is meant for? 2) On the Atari 2600 adapter how do I use the female jack? 3) On the ...

Finally I was able to assemble a very little part of what I've ordered but I can confirm that the alternatives parts are working fine viewtopic.php?t=3433

thank you!

Finally I got enough components to assemble a USB snac and a couple of adapters (I'm still waiting PCBs for HDMI snac, PCE SNAC, cables, ports and some LLAMA adapters ) but I was able to test the mega drive PCB with a 6 buttons controller and I can confirm that the mod is working!

Here's the github of SNAC: https://github.com/blue212/SNAC.

Thank you for the claricications, now I have a better undersanding of what I need .
It's really difficult to source components these days even for a couple of small projects (some SNAC and LLAMA stuff)

Thank you very much for your indications, maybe I've found another suitable substitute for Q1, I think that 595-TPS7A0533PDBZR could be a good candidate too, what do you think? Just to find some alternatives.

For the MOFSET what are the important parameters to look at? I was looking for a SOT23-3 Nchannel RdsOn 3.5 Ohms.

I'll try to give a look.. I don't know if I had bad luck but when ordering components on ebay, even if in the auction it's reported that the seller is located in Europe the item is shipped from china so I'm always a bit reluctant to place an order for those items. At least on ebay there's the PayPal protection..

Thank you for the suggestion but from Farrel U1 is out of stock at least untill 2022

Soldering something like that should be pretty easy.. At the moment the hardest pitch I soldered was the ps1 digital flat. n8KCYhe.jpeg I'm not a professional by any mean anyway. The problem is not soldering and assembling but finding all the required components in the same place without going in some aliexpress auction where usually you'll end wai...

Hello everyone, I'd like to build myself a SNAC for my MiSTer but I'm really struggling to find some components, exspecially those 2: - U1 - PMIC-LDO-XC6206P332MR-G (SOT23) - Q1-Q8 - BSS138 I usually order from mouser because since I'm in Europe I have free shipping over 50$ and no customs fees but I can't find thoese parts anywhere else. Is there ...

Thank you again! We can now try to make a couple of PCBs for LLAMA!

Sorry for bothering again..
I was looking at the scheme with a friend to make 2 PCBs for LLAMA but I don't understand what D7 D6 D5 and D4 stand for, what's their meaning?
They aren't connected to any db15 port, right?

Great I'll try for sure thank you very much!

Is there a link to buy or a scheme to refer?

Thank you for clarifying!
I was pretty sure, once I saw that it was working with a shorter cable that the problem was on my I/O board.
I find this LLAMA adapter to be very functional I only wish that the db15 port supported a 6 buttons arcade stick but I think that is impossible since there aren't any low lag adapter for that

I may found the answer, and added pull up resistors too:
viewtopic.php?f=32&t=3433&p=35292#p35292

I compared the schemes of the 5.5 and 6.1 versions and I've tried to add IO6 signal and a pull up resistor for every serial signal:


Now I need a SNAC with the genesis adapter to test if it works.
The pull up resistors solved the flickering inputs with a relatively long USB 3.0 cable using LLOAD input device

I've got a little update. The cable provided with the LLAPI device was not defective! Looking at the schemes of my I/O board v 5.5 and comparing them with the 6.1 I've noticed that on the serial area there is one more signal (IO6) selectable with a jumper and some pull up arrays for each signal of the serial port. So I decided to try to add IO6 to ...

I'm sorry for the confusion, I meant the adapter for USB controller (serial port to USB): https://misterfpga.co.uk/wp-content/uploads/2020/03/MiSTer-SNAC-Addon-Board-USB-Buy.png EDIT: OK I misread the functionality of SNAC I didn't notice that you need an adapter serial to usb and then add the usb adapter for the controller. I was thinking that usi...

Are the schematics to mod the v 5.5 available? I'm not finding them unfortunately.

Thank you in advance

Hello, I've bought my mister a while ago and it came with the LLAPI input device from bootsector. It works really but I'd like to try snac too (mainly because of the possibility to use a USB device too). My questions are: I've read that for some adapters like the mega drive one I need the last revision due to a lack of connections on older revision...

Problem solved, I simply misread the pinout so instead of VCC I use gnd now it's working fine
