PS3 Any specualations on ways to use a custom output resolution? 720p90Hz? 240p?

[quake]

is it a hardware limitation, can the RSX/DAC handle those resolutions (pc gpu can)
How can those be implemented?

Primarily interested in 240p for ps1 games

Would love to know if there's a way to output 480i & 240p over HDMI as well.

240p is 480i

ps1 games are scaled to 480p or 480i, depends on output. lowest res is 480i for analog and 480p for hdmi.
wii is a great emulator for 240p.
