Only the Cconout output not use the blitter.
Like some peoples I have bad pixels at 25/50 MHz for example with the GEM garf_rubberbox.
It's impossible to rewrite all original VDI routines who use the blitter, the best way is to use NVDI. Nevertheless there are a blitter SDRAM patch inside the flash patched TOS who use a buffer in STRAM for the VDI functions vro_cpyfm, vr_trnfm, and vrt_cpyfm.
The system fonts is also copied in STRAM because if you have a TOS 4.02, the addesses used inside the TOS 4.04 are not at the same place (the blitter use always the 24 bits space on the motherboard).
So, this features seems better than a CT2 ;-)
Regards,
Didier.
