Detailed Description

Boolean type and constants.

Warning

TRUE is 0xFF, not 1! This matches SNES convention where bit patterns are often used. Always compare with != FALSE rather than == TRUE.

if (flag) { }         // Good
if (flag != FALSE) {} // Good
if (flag == TRUE) {}  // Bad! Will fail for non-0xFF truthy values
