This page contains a list of addresses in the GY454X VerE real ROM that follow a POP PC, RT, RTI or BAL instruction but never get called or jumped to.
This list was created with the help of my nX-U8/100 disassembler PyU8disas, which is still in active development. Therefore the list may not be 100% accurate and may get updated over time.
user202729 also labeled (and even used) some of these unused functions, obviously with no idea they are actually unused.
