 ### Fixed
 
+- Memory view "Follow" showed wrong position
 - Disassembly sometimes only showed hex bytes instead of opcodes
 - The VIP-CHIP-8E interpreter had a typo leading to `BBnn` not working ([#12](https://github.com/gulrak/cadmium/issues/12))
 - Disassembling 0x7C, 0x7D or 0x7F generated single byte opcodes instead two byte ones ([#13](https://github.com/gulrak/cadmium/issues/12))
