This will always say R4000 if it's a R4000 class CPU.

Which says that you have an R4400SC V5.0.

Good spotting, the CPU detection code has a bug causes only V4 CPUs to be
detected as R4400.  The difference is just cosmetics; R4000 and R4400 are
almost the same.  Especially it's unrelated to the file corruption problem.
