CROSS-LIB-HD

May 4, 2026 · View on GitHub

CROSS-LIB-HD is CROSS-LIB with a higher number of tiles but slightly larger binaries and fewer colors on a couple of targets.

REMARK This is still a work process.

CROSS-LIB-HD vs CROSS-LIB

Both CROSS-LIB and CROSS-LIB-HD have 37 fixed (26 letters, 10 digits and 1 empty tile). The main difference is the total number of supported tiles (fixed and redefinable).

CROSS-LIB-HD: at least 128 total tiles, i.e., 91 redefinable tiles,
CROSS-LIB: supports at most 64 total tiles: i.e., 27 redefinable tiles.

Same targets as CROSS-LIB

It is possible to support the same set of targets as CROSS-LIB even for targets that cannot have 91 redefinable tiles in the same colors and video modes as the ones used by CROSS-LIB.

We can use:

fewer colors -> When a given target cannot have 91 redefinable tiles for each available color in CROSS-LIB, it may be possible to have those tiles with fewer color variations or in a different screen mode.
ASCII tiles -> If there were a target with graphics that cannot have 91 redefinable monochromatic tiles, the target can still use 91 ASCII characters (no UDG mode).

Compatible with CROSS-LIB

Source code of games and programs written with CROSS-LIB are compatible with CROSS-LIB-HD.
