Changes

== Oddities ==

* Despite having different names and opcodes, RETI and RETN are in fact the exact same instruction

* RST instructions are just a CALL instruction to a fixed address baked in the instruction itself

* Contrarily to what the syntax of the instructions JP (HL/IX/IY) suggest, PC will be loaded with the contents of the register itself, not the indexed value. Those instructions should be understood as JP HL/IX/IY
