BLT (Branch if Less Than) is a Super FX opcode that performs a jump if the negative 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:

 BLT $+4h
