DARKSOFT CPS1 Multi - Support thread

Hi folks. I just ordered the ltd ed CPS1 multi DSP16A from Highscoresave.com today and am excited to get it in hand.

I have 3 x donar boards and all have the same c-board 92631C-6. I understand these are only rated as 'good' donar boards in the guide which is not ideal, but I see they require a decrypted romset to function. I've searched the archive but cannot see a decrypted set anywhere. The CPS2 set is freely available, but only the standard CPS1 set.
Any assistance is appreciated. I cannot for the life of me recall which historical Mame version used decrypted roms. Is there a rom builder available? Or any recommended software to decrypt them?

Apologies if this is dealt with elsewhere, I just want to be prepped for when it arrived early next week. Can't wait!

Update, just spotted this post from @Darksoft. So its only the 1.5 roms that are encrypted?

No, only sound CPU was encrypted. In the rest of the games, what changes is the chip in the C Board. The multi is able to inject keys and make a C board with a B-21 if it's proper version, to work as any C Board.

Don't mess with that. IMO is better if you get a repro C Board or try to find another donor which has not been modded. My 2 cents.

Thanks for that. I guess I'll need a to find a repro board.
 
Can anyone tell me why I am getting these weird colors on street fighter characters? I haven't noticed this on any other games (so far). I see the same effect on all version of SF2 that I've tried.
I see no issue when I put the original B+C (SF2 world warrior) back on the A board.

Hi. I post this very, very strange "issue" just in case anyone has experienced it. In fact, I am almost sure that the following is not a Multi CPS1 issue but only a problem with the rom itself or... I dont know...

- Street Fighter II: Accelerator Part 1 (Hack) (World/Euro):
When playing as Guile: medium and strong punch didn t work if you are standing. Its very strange because the sound goes on but the punch is not launched. However, it works if you are crouching, jumping, special attack, etc.
The Accelerator Part 2 doesn t have this issue.
Anyone?
Thanks!
 
I think it was very well in place haha, still managed to gently take it out and put bit back, still the same as before, static : (amplified like crazy so you can here something helpful(?)

(I did screw it back obviously👍)
Follow up, Darksoft sent a we dsp15a q-sound module replacement, but just before it got there, I received a PLCC extractor and reseated the Lucent Chip, and it did the trick8o (as a warning, do not attempt this without said extractor and without knowing what you are doing, it would be a shame to brake one of those chips:thumbup:)

totally unrelated, but I did end up using the "2024-01-05" set (also not sure how it interacts with the 3 other sets, since the maning is different, so I'm not using those for now), but some folders aren't in the right order due to the modified folder date in the archive...I can swear I have seen a post somewhere here recommending a software to do this kind of sorting but can't recall the name ;( can anyone help out ? thanks a lot in advance! (I did try advanced renamer but not sure how to get it working)
and happy gaming everyone :D
