oh yeah for sure I don't think it's a bad fit for your use case tbh just wanted to share my personal hangups.
i really wanna play diamond/pearl (my OG) but really cba with the two screens smooshed into one on my retroid pocket flip 2 but I didn't even consider it for steamdeck ... that doesn't sound terrible w how big the screen is
considered the remake/remaster/whatever for the switch and could cope w the much less cool gfx but last I looked into it it didn't emulate well
