[Solved] Stuck on Green screen CP2 Multi.

[piscian18]

Nightwarriors Darkstalkers board Rev 3 PalF

Board was a suicided battery melt functioning fine with a infinikey.

I removed the infinikey and installed the multiboard, formatted sd provided by HSS, copied rom rollup basic. One rom did boot MVC unlocked with jailbars. I read that the roll up is encrypted now so I went back and did the key writing wires. Nothing has worked since.

Green screen except when writing rom and key which then it switches to black screen and switches back to green after completion.

Pins look good, Ive reseated the boards twice.
reformated SD card(windows)
Tried several roms
installed key writing chip
swapped b boards
shorted exc5
shorted jumpers

verified continuity for key writing pins.
Donor board worked previously, but I also tested a spare XVS which works fine.

Pictures attached

My soldering jobs not the greatest, I did low heat 230c, nothing looks damaged.

I'm out of ideas. I was trying to find decrypted roms so I could see if maybe my key writing isn't actually working, but no one seems to be posting them anymore. I cant find a link to the latest firmware but this board is only a week old.

Fixed, ultimately had to clean the A board pins and reseat my B board caseless directly on. not sure why, board worked fine mostly before the install, but A boards are always kinda flighty.

Maybe this helps?

The Definitive Guide to Fixing Your CPS2 Multi Kit

I think your interconnect board is not seated all the way. It may seem and feel like it is. But give it an extra push down extra firmly. Even if it seems you already have, try that. That was a problem for me before.

 

[piscian18]

You need the connector between the multi and the daughter board? I went back and pressed them together. The boards are mashed together so hard at this point the pcb will break I pressed any harder.

 

[Anselmo]

yep. That looks good. Still not working?

 

[Anselmo]

what size SD card are you using? Did you confirm its formatted as fat32?

 

[piscian18]

yeah fat32, I bought the 8gb packaged with the board and later tried my own 32gb. They are detected and seem to write just fine.

try gently but firmly pushing all the boards together from both sides (note carefully where the interconnecting pins are and concentrate on those areas). I hold the whole thing vertically and with the base of both my hands I gingerly press them together on all the sections where there are pins which need to inter connect. Also the board connector part, put pressure on both sides, from both sides (two hands from top and botton until it all goes together as far as it can without too much un-even pressure).

Does your LCD screen say "injecting key" (or something close to that) when you turn on the CPS2 ?

 

[piscian18]

still no luck. yeah it says programming key when you load up.

Shorted the EC5 cap. I've literally tried everything on the list now. I'm starting to wonder if there's a capability issue some how. As stated the donor board was suicided, so bad so the battery dripped on the board, but didnt appear to break anything. To fix that Id installed a Infinikey which as I understand it circumvents the rom holding the encryption key by sending the key directly. Does the Darksoft need that original key rom to be connected and functional? I'm wondering the key rom is bad.

I have a spare board but its original on battery, though it looks like it was modded for hot swappable battery. Still..Im pretty reluctant to mess up a perfectly good board.

Take off the infinikey. Double check the key writing wire job. Make sure the SD card was extracted using 7-zip.
