Designing a host PCB to simplify wiring and putting into an enclosure.

[multigamesystem]

Ive been designing a 3D printable case for the the Pico + Dreamcast extension cable end. So far its gone pretty well with just wiring directly to the pico but after a few attempts Ive realized its easy to damage wires and the resistors are a pain point. So Ive designed a PCB to simplify the wiring. I was gonna design around the recommended 74LVC2T45DC logic package but I ran out of steam. Whoops forgot to change the text from 1 Player to 4 player. I just modified the board to have 3 more player inputs so I didnt waste time making 2 different PCBs. Oh well no big deal.

Crap @Tails86 I accidentally wired up player 2 to GP16 + GP17 I sent off to get the boards made already. How hard is to to modify the program? Dont judge my schematic Im not an electrical engineer by any means.

Not hard. Definitions are located here: https://github.com/OrangeFox86/DreamcastControllerUsbPico/blob/main/inc/configuration.h#L48

I found those but how would I go about modifying them and recompiling into a pico program?

Build instructions are on the readme: https://github.com/OrangeFox86/DreamcastControllerUsbPico?tab=readme-ov-file#build-instructions-for-linux-and-windows
I created this branch and included the uf2 files: https://github.com/OrangeFox86/DreamcastControllerUsbPico/tree/p2-pin-16/dist
(change was not tested)

Thanks for your help @Tails86 ! Ill test and report back when the pcbs arrive. Should be here by Monday.

This looks great! I tackled a similar problem but had a board made using HDMI ports for all 4 players. I swapped 3 and 4 though and need to change the firmware. I am using HDMI since the adapters I have are from the Bliss-Box 4Play. Where can I source the extension cables you have with the 4 pin sockets?
