Editing Save breaker changes (section)

== Level changes ==

=== Components ===
In general custom components (CCs) are now allowed to be placed in (almost) all levels.

Any CCs that contain built-ins (even recursively) will not be included in that level's build menu.

Placing and then editing a CC to include a disallowed built-in will result in the level not being scored.

=== Outputs ===
Most levels now distinguish between disconnected(Z-state {{Z}}) and zero or {{Off}}. If the level expects {{Off}} or <code>0</code> it will not accept {{Z}}.

{{Level|Bit Switch}} is a the first level where this might be noticed, some previous solutions that output {{Z}} will no longer pass and need to be fixed.

=== Overture ===
The Overture opcodes have changed, but the Overture levels are relatively unchanged otherwise.

{| class="wikitable"
! Operation
! Old opcode
! New opcode
|-
| OR || 0  || 1
|-
| NAND || 1 || 0
|-
| NOR || 2 || 3
|-
| AND || 3 || 2
|-
| ADD || 4 || 4
|-
| SUB || 5 || 5
|}

This can be fixed by:
{{spoiler|Replacing what used to be Byte OR gate with a Word NAND gate set to a width of 8 in your Overture ALU.}}

{| class="wikitable"
! Condition
! Old
! New
|-
| Never || 0 || 0
|-
| Always || 4 || 1
|-
| Equal to 0 || 1 || 2
|-
| Not Equal to 0 || 5 || 3
|-
| Less than 0 || 2 || 4
|-
| Greater than or Equal to 0 || 6 || 5
|-
| Less than or Equal to 0 || 3 || 6
|-
| Greater than 0 || 7 || 7
|}

This can be fixed by:
{{spoiler|Rearranging the bits from the condition input.}}

=== LEG ===

The LEG levels in CPU Architecture 2, and beyond, have been completely replaced with the Symphony (a whole new architecture) levels, there are too many changes to list here.
