-- Information: --
-- Video Mode 2 (official) --
-- --
-- Vertical tiles on VRAM, --

-- Default value is: --
-- VRAM_TILES_V=32 --
-- --
-- Numbers of screen sections, --
-- can be changed by compilation. --
-- Default value is: --
-- SCREEN_SECTIONS_COUNT=1 --
-- Only height size and position of --
-- screen sections can changed: --
-- * width size = VRAM width tiles, --
-- * height size = 1 to 208 pixels --
-- * numbers = 1 to 28 sections --
-- * position = X axis --
-- --
-- --
-- Numbers of video lines to render, --
-- can be changed by compilation, --
-- but is not recommended, changes the --
-- CPU cyles. --
-- Default value is: --
-- FRAME_LINES=SCREEN_TILES_V*TILE_HEIGHT --
