Ratchet & Clank: Size Matters - Movement slows to walking pace upon jumping of hitting with wrench

[LinAGKar]

Game or games this happens in

UCES00420 - Ratchet & Clank: Size Matters

What area of the game / PPSSPP

Just started a new game, and jumped around on the starting beach. If you run and jump or use the wrench, the movement slows down to walking pace, and then returns to running pace only once you move the analog stick. It doesn't happen every time, it seems more prone to happening when running to the right.

What should happen

Movement continues normally

Can confirm this also occurs in (UCUS-98633? Ratchet & Clank - Size Matters (USA) (En,Fr,De,Es,It).iso, CRC32=c711ede4) in latest git build (28532fe) using the libretro core (-DLIBRETRO=On; RetroArch v1.10.0) as installed by RetroPie 4.8 on Raspberry Pi 4B Rev 1.2 (b03112) (ARM Linux / Debian 10 "Buster").

Frequently after performing an action (jump, swing wrench, etc.) while moving with the analog-stick, character movement will briefly slow to walking speed; movement using d-pad seems unaffected. I found this old reddit post which seems to be describing the same issue, and then I found this issue page, which seemed like the best place to report.

Updating, I can trigger this reliably by swinging the wrench while moving diagonally (pre-post edit: you don't even need the wrench. just get him walking, not running -- push the stick only halfway -- in any direction). Once walking, in any direction, is initiated, movement with the stick will then be limited to walking speed for as long as only diagonal (or no) movement is maintained; running speed resumes only when the stick is moved to any of the four cardinal directions, or when the D-pad is used.

(Occurs in master b93be29 as well as in stable v1.12.3. Also confirmed I am using UCUS98633 according to my SAVEDATA dirs.)

In PPSSPP proper, go to Settings -> Controls -> Calibrate analog stick. Next, move around your analog stick and observe the range of motion especially in the corners. If it doesn't reach the corners, consider enabling "Circular stick input" if not already enabled.

The PSP analog nub (it didn't really have a stick) had a physical range that was circular, but it exposed its coordinates to games as a square.

Modern devices vary, with some exposing their range as a circle and others as a square.

For libretro, you're on your own. I'm not sure how it exposes analog stick values or how you can control the calibration, and since its apis were designed for weaker systems (the PSP is ~93x more powerful than a SNES, and ~10x more powerful than a PS1) it has gaps when it comes to things like this, multithreading, etc. You'll in general experience more bugs, worse performance, and other limitations on libretro.

Thanks. This does seem to fix it in stand-alone.

I'd still like to use the libretro core. From what I can tell it's not a separate project, but rather just this one, built with a particular command-line parameter. Where would be the place to request, to have this "circular stick input" added as a "core option"?

I thought it might be simple enough to do myself, but this doesn't seem to have worked: https://github.com/s1eve-mcdichae1/ppsspp/commit/51acaad835b9da7744c1aec544c6a16fd6a87bd0

I get the option in my core menu, but it doesn't seem to do anything (after enabling it, the diagonal movement issue still persists.)
