BBC extended screen MODEs
MDFS::Apps.Graphics.NewModes Search
There have been many programs written to give extra modes on the BBC, but they have usually given extra colours, but at the price of losing character resolution. The usual example is a ten character, 16 colour mode. What I wanted was extra colours, without losing character resolution. The programs here gives an approximation to RISC OS MODEs 8 to 14 by using characters four pixels wide.
