This probably isn’t a good time for new feature requests, but there never seems to be a good time!
I notice that in the August release there are a number of new HDMI video modes available that used not to be supported. I’m wondering if some more could be added.
VIC #60 (or possibly #65) would be quite useful - that’s 720p/24Hz (or 23.98). This is quite a common resolution for blu ray rips; and for the immediately foreseeable future, that’s the resolution people will be running Netflix and Disney+ at.
Non-standard modes that would also be very useful to me are 480p/24 and (less often but sometimes) 720x540/25Hz (or 50Hz). Again, both are quite common on Netflix.
Maybe you could even allow users to define their own modes with the relevant timing parameters?
