I flashed in Nov64 CCD Plus to pages C,D and Zenrom to page F - all ok (turn off CCD lower case alpha), but GTO .. and GTO ... dont work, after first and rest . on display GTO ST _
If Zenrom in page C, CCD Plus in pages D,E - GTO .. and GTO ... worked as expected, but extended CAT's from CCD dont work.
Howto fix this trouble?
Where find info about CCD flags in [Reg c, Byte 4, High nyble], 7 bit - on/off lower case alpha, whats does 6,5,4?
