Hello! So I have an Optimize board installed on my Original 3DS XL by another individual whom I've unfortunately lost contact with. More recently, the board was replaced by the same person because the previous board was having problems. I don't know the hardware revision or firmware version of the replacement board. I've been having trouble getting it to work with the n3DSview software that he originally recommended using with the first board, and which I had been using with the first one with decent (though sometimes inconsistent) results until it apparently broke. When I found that you made this cc3dsfs program, that was huge for me! Unfortunately I'm still having trouble getting it to work consistently.
I tried the latest stable release first. Every time I tried connecting my 3DS it would briefly say "Connected" for a moment before showing the error "Disconnected: Read Error". Then I tried downloading and installing a cypress driver you had linked on a github closed issue (latest from Microsoft Update Catalog). Then when I tried connecting it gave me video and audio feed (though with an occasional flickering grey screen and much garbled audio). Now that it was connected, the "Optimize Settings" option appeared in the GUI menu and I was able to add my optimize key. However, after disconnecting and trying again, I only got the "Disconnected: Read Error" every subsequent attempt.
So next I tried the latest nightly build. I ran the driver installer bat file, restarted my computer (Windows 11, HP Pavilion Laptop) and tried again. First, it gave an error right away that said "Capture Start: Failed." Then after trying to connect again it gave video and audio for a second before disconnecting and giving the "Disconnected: Read Error." Then, every subsequent attempt resulted in the same error but without the brief video & audio.
In my device manager I find the following details:
Device: Cypress FX2LP No EEPROM Device
Provider: Cypress
Driver date: 6/24/2024
Driver version: 1.3.0.5
Hardware IDs:
USB\VID_04B4&PID_8613&REV_:001
USB\VID_04B4&PID_8613
(The Hardware IDs were unchanged from before the nightly driver installation.)
One other potentially relevant detail is that the original Optimize board installed in this same 3DS XL also had somewhat inconsistent capture behavior. It always had at least one n3DSview mode that worked, but different modes would work inconsistently, and I was never able to get proper-color 3DS game capture reliably. The replacement board behaves differently, but I'm still having the connection issues described above.
I have also tried multiple USB cables and ports but to no noticeable difference.
I would appreciate any help or insight you may have in the matter. I know you have incorporated more support for Optimize board recently, so I look forward to hearing from someone who knows what to look for with these boards since documentation appears very sparse. Please let me know if there is any additional information you think would be helpful for diagnosing a problem and I would be happy to help. I am really really hoping I can get capture working again with my 3DS like I did over a year ago with my old board when it was working.
