1280x768 also doesn't show up in the in-game resolution list.
Is there a way to force a custom resolution? The registry entries for the resolution are just indexes. Even converted to decimal these values don't make any sense.
[HKEY_CURRENT_USER\Software\Telltale Games\Sam & Max Season 2]
"Screen Resolution First"=hex:00,00,a0,40
"Screen Resolution Index"=hex:00,00,00,41
Also, I don't suppose there are any plans to back-port this new renderer to Season 1 so that we're not stuck with 4:3 resolutions there?
