I recently gave a small talk about this and listed the applications I had for it in the past few years: - Test low memory environment - Add memory tracking - Ignore double frees (fix broken programs) - Cache allocations / lookaside lists - Trace all file operations - Seamlessly open compressed files with fopen() - Speed up time() as program sees it - Offset time() to bypass evaluation periods - Alternative PRNG - Intercept/reroute network sockets - Trace various API calls (useful when debugging graphics APIs) - Force parameters to some API calls - Set a custom resolution not supported by program - Switch between HW and SW cursor rendering - Framelimiting and FPS reporting - Replace a library with a different one through a compat layer - Frame buffer postprocessing (e.g. reshade.me) - Overlays (e.g. steam) E: format
