Target Practise

Hello everyone! We’re back with another devlog!

Instructor

I managed to finish up all the instructions (minus the HL sections of those because that uses the value in the combined HL register as a pointer to memory, which I did not yet add) that were already in the enum (screenshot from last devlog). I also just added the INC and DEC instructions, which increment or decrement the value in the target register or byte in memory pointed to by HL.

It was a bit of a hassle to figure out how I should do the target enums, since there is an 8 and 16 bit version of each INC and DEC, each with different targets. INC8 can target the byte of memory pointed to by HL, whereas INC16 can point to HL itself and the other 3 16 bit registers.

See y’all next time!
