BLT (Branch if Less Than) is a Super FX opcode that performs a jump if the sign flag is unequal to the O/V flag, effectively checking for a signed less-than comparison (compare BCC which is an unsigned less-than comparison).
According to fullsnes, the official documentation has BLT exchanged with BGE. [2]
No flags are affected.
Syntax
BLT e
Example
Let the sign flag be set and the overflow flag clear. This instruction jumps the program forward 4 bytes:
