I sent you an email over on EAB but I guess you did not get the notification.
Does the OSSC accept the Dbl modes over SCART seeing as how they are not 15KHz? Hoping I do not have to use the VGA input for these. However, that HD720 mode looks so good, I might not care about the Dbl modes anymore. Then again, HD720 isn’t 15KHz either (but it is close). Does it slow down a lot in 16 colors (my A1200 has an ‘030 and I find 16 colors acceptable)? Your example above looks to be 4 colors.
