Bringing up the keyboard is abnormal for all homebrew software, for example, SwitchWave-1.1.2-e9a7737. If you want to test it, use this software: in the Editor, select the text input field and press X.
These issues have already been made very clear in the changelog, such as save-state compatibility, game running speed, etc. I'll paste them again here:
Updated Ver1.1 rc1 (2026-09-22)
Core upgraded from 0.92 to upstream stable 1.1 (b86390e)...
First enable the background mask. The mask file name must match the ROM name (case‑sensitive). This feature doesn’t work well; I’ll revise it later when I have time.
Scale2x and Scale3x, similar to xBRZ, are a compromise implementation on the performance-constrained Switch.
After adjusting the parameters, you need to toggle the aspect ratio. It's odd, but that's the only way for now.
Some fixes and PC port features.
Fixed system crash when BIOS file is missing.
Fixed crash when selecting 'Undo Load State'.
Fixed game grid UI navigation position saving.
Fixed emulator freeze on 'Reload Shaders'.
