@DjDiabolik said in Input Lag - How can "CHECK" if present in Retroarch core / Standalone emulator?:

anyway for my next arcade kit I was considering buying something similar:
RP2040 Advanced Breakout Board on Aliexpress

Nice. That creates added value to a plain RP2040, pinheaders and Dupont wires. FWIW, here is the non-commercial link with all the tech specs.

Great you have some takeaways/learnings, that's the Raspberry/RetroPie spirit.

PS: The Sanwa's do have a high price tag but I never regret my invest: Mechanical still precise after ~5yrs, no maintainance needed, colors fresh as of the first day (my setup is partially exposed to sunlight during the day).
