    I remember when I started learning asm 6502 for coding on my student club's commodore 64, even though I don't have time to work on it anymore, I found it somehow way more fun than coding in high level languages such as C#

    Also, having the label on the right is very strange to me.

    It looks similar to Z80 asm which I used in the good old times making calculator games, ti-86 :)
