What's new
My kit has recently started giving a green screen. When it happened last i opened everything back up, checked no wires were loose and put it back together and it worked again (that was 2 days ago), but i didn't actually do anything to it. Tonight i turned on the machine to get some street fighter going and green screen again.

Instead of me stabbing in the dark what would be the best thing i should check for problems?

edit: some additional info, if I flash a new game on i get a pattern on the screen instead of solid green. If i flash a different game the pattern is a different solid screen (not moving) but changes each game.

The pattern is normal while flashing a game. It should then if you have the key writing wires flash the key, reset and load the game.

If you're getting a green screen it could be a couple of things:

- EXC5 might be retaining keys, short it with a large screwdriver to confirm

- Main program ROM board isn't making good contact, check your pins, seating and it may potentially be bad sockets

- Connection between A and B boards is not making good contact (I would think this is the most likely since you noted it worked after you opened the B board, meaning you reseated the A and B)

Are you using the factory clips to hold the A and B boards together?
 
Thank i will try reseating A+B that might be it, in my astro city my CPS2 board sits on its side, not flat so maybe that has something to do with it

Also there is no battery on the board so i don't think its a key retaining thing
 
No, the capacitor holds the keys. Sometimes it holds a charge too long and doesn't allow the new keys to be flashed over the old and it needs to be cleared

If you're mounting a CPS2 in an Astro (I do the same) the board clips are essential. You will have issues without them
 
Just an update - looks like that was the initial problem. Reseated A+B and it worked sitting on the floor, wen't to put it back in the astro and i dropped the entire B board (not from very high) and then got a black screen doh!

Took it all apart, reseated everything and it's fixed.

Where did you get your clips? I've put some tight rubber bands around it not sure if that will be enough or not.
 
Here’s how I did my wires since I didn’t have a plug for CN9.

I get a solid green screen, and I found out why I had a friend solder the wires because I don’t know how and couldn’t bare to try. And he jacked the pad up where the key writing wiring goes for the clock the wire isn’t even soldered to it because the pad is done, all the others are soldered. So pretty much thinking I’m just going to have to purchase another darksoft Kit ‍♂️ +400 bucks wasted time to save up for another kit.
 
Or you could just solder to a different point for the same connection.

Everyone in this hobby should learn basic soldering skills. Perplexes me that so many people ruin those pads.

@Darksoft can the PCB be redesigned to include a header for the key writing wires?

This has happened to a few people. It can be repaired without replacing the kit or you can run the decrypted ROMs without issue. Since you're in the US, contact @Mitsurugi-w

It's caused by using too hot a soldering iron and holding the iron to the pad too long. You should be tinning the wire, holding wire to pad and heating the wire. And not using the iron at 400C

Helps to add solder (and optionally flux) to the pad first too.
 
I think anyone that is looking to do basic soldering should go check out voultars YouTube page :) he shows a lot of good techniques for basic soldering, as well as soldering more complex smd stuff.. here's a link to one of his vids about his tips and tricks to fast and proper soldering :)

this more concludent imho ...this is what the peoples must know (i start to use my solder station bought in March 2018 when i solder the key writing wires on my CPS2 Multikit in October 2018)

this is what i've done 2 weeks ago with my tools :saint: :whistling:

I was actually thinking of posting that video instead, but I just liked how in the one I posted he actually explains what he's doing..

I definitely encourage anyone who isn't super confident in their soldering and wants to start to check out his channel though, not only for soldering to the pads on the CPS2 multi, but also if they want to get into modding other consoles, as well as recapping.

I'm pretty confident in my soldering, but his videos have definitely helped me to get even better :)

I'm a big fan of Voultar. Everything i know about soldering and retro consoles mods are from him :saint:
 
Hi,

I just ruined one of the key-writing pads :(. Specifically, I ruined the DATA one. Where it used to be copper, there is none anymore. I used too much heat, apparently. Is it fixable?

If not, can I still play the unencrypted version of the ROMS? Do I need to change the firmware to do so? Please don't tell me I have just sent 400 bucks to the trash T_T.
 
you can still play unencrypted versions but if you want to fix it, please contact @Mitsurugi-w. He'll fix it for a small fee.
 
Do I need to change the firmware in order to run the unencrypted version of the ROMS? I bought my kit a couple of weeks ago, so I'm guessing my kit came with firmware version 3.1.
 
Kit came with latest firmware and you don't need to change it, just replace the games in your ROM folder with the ROMSET from Team Avalaunch.
