VIDEO CONTROLLER
VIC-IV advanced rasterised video controller, like the VIC-II and VIC-III no framebuffer
Native resolution 1920x1200 (192MHz pixel clock)
Supports all documented VIC-II modes (hi-res, multi-colour mode, extended-background-colour mode, sprites) and VIC-III modes (bitplanes)
Independent horizontal and vertical hardware scaling allows text and graphics resolutions as high as 1920x1200 and as low as 60x38
Separate 256-colour palettes for sprites, bitplanes and character graphics, allowing up to 1024 colours on screen without changing the palette in real-time

DEVELOPMENT OPTIONS
Use Ophis with the -4 option to target the 4502 CPU. The etherload utility can be used to push compiled programs to the MEGA65 practically instantly to make for a convenient cross-platform development environment. MEGA-OS will support interprocess communications, making it possible to write assemblers and compilers that assemble directly into a separate process, and then launches that process when it is ready. Thus it becomes possible to use the MEGA65 as an 8-bit development platform for 8-bit software (or to run a cross-compiler for Linux or Windows if you wish to be really strange).
