The codes would both overwrite where it should and 16400 bytes after where it should. The bug was caused by a usage of an incorrect register.
Based off codehandleronly.bin. Improves support for codes with conditionals due to adding cache invalidation on stores. You also have support for mode code lines at once before Dolphin freezes at startup.
Added a check to ensure that the number of codes fits in memory (maximum 231 codes). Store a copy of codehandler.bin in the Sys directory.
