left and right socd

Hi there!
I’m using a Hitbox built on the GP2040 firmware and have a feature request for SOCD (Simultaneous Opposite Cardinal Directions) mode customization.
As the firmware already supports Up Priority (a.k.a. Stickless), Neutral, and Second Input Priority modes, I won’t dive into existing behaviors—you likely know them inside out! My ask is simple: could you implement a new SOCD mode where:
Left/Right: Follow the mutual override logic (consistent with how opposite horizontal directions work in Second Input Priority), with no neutral output when pressed simultaneously.
Up/Down: Default to neutral (center position) when pressed together (matching the behavior of the Neutral mode for vertical directions).
In short, this mode would combine horizontal override (Left/Right) and vertical neutral (Up/Down) behaviors. It’d be a great addition for players who prefer distinct SOCD rules for horizontal and vertical inputs.
Thanks a ton for your incredible work on the GP2040 firmware—we really appreciate it!
Best regards,
（I wrote this using translation software, and I apologize for any misunderstanding.）

Hello fellow programmers, I have a similar requirement to the original poster. I am also using a game controller based on the GP2040-CE. Due to the needs of my game, my custom controller has 8-way directional input, which includes direct inputs for upper-left, lower-left, upper-right, and lower-right in addition to the normal 4-way directions.
When I press the lower-left direction first and then press the right direction, the controller outputs lower-right. Obviously, this is not reasonable. The SOCD rule I want is a diagonal-aware last-input priority (overwrite) rule: when I press lower-left first and then right, the output should be right; when I press right first and then lower-left, the output should be lower-left.
I would appreciate any feedback. Thank you again.

@LxxL307 - Breaking out SOCD a little more into a per-axis 'advanced' type mode is something we have talked about before and are open to exploring. This would be a great thing to see from a developer that would like to prepare a PR and present it to the team.

@kurtkurtkurt - This sort of logic is not something that we would be interested in pursing at this time as it appears too much like direction manipulation. With your given example the SOCD is cleaning as expected.

If this is something you would like to pursue I would recommend doing so in your own fork of the project.
