To help with low firmware issues, (honestly should use title override for accessing homebrews so you have more ram) but you could make an emunand and update it to latest firmware.Very good idea to select different aspect ratios during playback.
At the moment, we use mpv.conf file with fixed aspect ratio (video-aspect=16:9) to get wide screen for older movies, but this is not perfect, because it is fixed to 16:9.
@proconsule54 if you wanted to go through the trouble for testing on lower firmware, you could make an emmunand and downgrade it.
