I just dusted off my PS1, it does work on real console! (Which I expected, I trust testing on Duckstation on interpreter mode) Just gotta make sure if you use a dual shock to set it to digital mode. Tested a Kernel copy and a none Kernel copy. No issues so far.
Gotta say though, playing RE1 on an actual PS1 at such low resolutions shows me how spoiled we are with the current state of emulation
