 Okay, memory addresses are nice, but you can't possibly expect me to keep track of all these addresses manually, right??
 Well, fear not, for we have labels!
 
-Labels are [symbols](https://rgbds.gbdev.io/docs/v0.5.1/rgbasm.5#SYMBOLS) which basically allow attaching a name to a byte of memory.
+Labels are [symbols](https://rgbds.gbdev.io/docs/rgbasm.5#SYMBOLS) which basically allow attaching a name to a byte of memory.
 A label is declared like at line {{#line_no_of "^\s*EntryPoint:" ../assets/hello-world.asm}} (`EntryPoint:`): at the beginning of the line, write the label's name, followed by a colon, and it will refer to the byte right after itself.
 So, for example, `EntryPoint` refers to the `ld a, 0` right below it (more accurately, the first byte of that instruction, but we will get there when we get there).

 That's a hexadecimal representation of 10, and we need to adjust it to become decimal. `DAA` or "Decimal Adjust after Addition," does just that.
-After executing `DAA` our accumulator will be adjusted from `%00001010` to `%00010000`; a 1 in the left nibble and a 0 in the right one. `DAA`'s exact behaviour is described [here](https://rgbds.gbdev.io/docs/master/gbz80.7#DAA).

 But why do we increment A using `ADD 1` when `INC A` does the same but is more efficient? That's because `DAA` evaluates the carry flag (see the linked description), but unlike `ADD`, `INC` does not affect that flag. So if the carry flag was still set from a previous operation<!-- note: this cannot happen right now, since IncreaseScorePackedBCD is only ever called after CP set the zero flag, which excludes setting the carry flag -->, `DAA` would add 60 points.
