* On the GBZ80, when an interrupt is triggered, the CPU automatically performs a DI before jumping to the interrupt handler.
* On GBZ80, RETI performs automatically an EI, unlike on the Z80. [https://rgbds.gbdev.io/docs/master/gbz80.7#RETI Source]
* RST instructions are just a CALL instruction to a fixed address baked in the instruction itself.
