# z80
|
||||
|
||||
i did day 13 in z80 assembly language too. it's in z80src
|
||||
|
||||
it uses zasm to compile and z80sim from [z80pack](https://www.autometer.de/unix4fun/z80pack/).
|
||||
|
||||
i edited z80sim to not print out that giant logo at the beginning but otherwise it's just the newest one built.
|
||||
the binary is included though lol.
