I've added some support for the higher resolution modes available with the ECS version of the Denise chip although this requires the CPLD version of the hardware, not the simple version.
This supports PAL 1280x256 and NTSC 1280x200) plus the 640x480 productivity mode as well as the standard 640 pixel modes.
(Also includes the interlaced variants of those modes)
The 1280 pixel modes only support 6bpp rather than 12bpp used in the 640 pixel modes but from the info I have seen online, the ECS chipset is limited to that in 1280 modes anyway.
Unfortunately it is not possible to auto detect between 640 and 1280 pixel modes so you have to manually select the right timing set using SW3 or the menu option (640x480 should be auto detected)
Set1 = 640 pixel modes
Set2 = 1280 pixel modes
