Known issues/2.0.16

Help expand it

This page descibes the early access verion 2.0.16 alpha. It may not be completely correct for the the current stable version, nor the latest unstable version. Help us update it, and you get a cookie.

A number of levels in version are known to be broken, and require some workarounds to complete. Some of these issues affect multiple levels, I only give the first level you are likely to come across them.

Unofficial partial fixes

Some of the levels can be fixed by replacing the game's campaign folder with an amended version from GitHub, provided by the user ERYK500.

• https://github.com/ERYK500/tc_campaign/

These are UNOFFICIAL patches - Please do not report problems to the game's developer. Instead, post on the TC Discord server in the #new-patch-talk channel.

This is a limited fix as some of the issues are engine limitations, which require a game update to resolve.

Symphony Counter

Missing bit-width tool and 16-bit

You should be able to place 16-bit components, but the bit-width tool might not be present in the level.

You can try pasting the following line into levels.txt (which is found in your save folder, check the location in Options):

symphony_register_1,true,10000,10000,0,Default

If your game is running, restart the game to ensure the changes take effect.

Some people report that the bit-width tool appears simply by going to the Sandbox then component factory. This works only if you first hoover the cursor over wire colors tool in a way that color panel stays open when the cursor is moved away and than click on Sandbox button.

If that does not work you can copy-paste 16-bit components from the sandbox.

The level log mentions "like in the register level", disregard that as that level has been removed, and this text not yet been updated to match.

Wire Spaghetti

This section is out of date for current 2.1.x alpha builds.

In the current local 2.1.48 Alpha files, campaign/symphony_1_nand/meta.txt already:

• uses the provided Main Memory and Register File components instead of asking the player to place their own RAM blocks;
• explains that register addresses are byte-addressed and must be multiplied by 4; and
• no longer tells the player to leave zr disconnected.

The older RAM-width workarounds and the zr note below applied to older builds only and should not be followed on current builds.

Integrating ALU

This section is out of date for current 2.1.x alpha builds.

In the current local files, campaign/symphony/test.si implements opcode 11 as multiplication (a_value * b_value). The old workaround about deleting or disabling the multiply unit should not be followed on current builds.

RAM

This section is out of date for current 2.1.x alpha builds.

campaign/symphony_6_ram/meta.txt already documents:

• 0 load_8
• 1 load_16
• 2 load_32
• 3 reserved
• 4 store_8
• 5 store_16
• 6 store_32

It also already explains that the load ports must be above the store ports to avoid a circular dependency. The older workaround in this section should be removed for current builds.

SSD

This section is out of date for current 2.1.x alpha builds.

campaign/symphony_7_ssd/meta.txt already documents:

• 0 load_8
• 1 load_16
• 2 load_32
• 3 pload
• 4 store_8
• 5 store_16
• 6 store_32
• 7 pstore

Also, campaign/symphony/test.si reads Main Memory and Persistent Memory by name, so the older RAM/SSD mix-up workaround does not match the current local files.

Instruction aliases

This section is out of date for current 2.1.x alpha builds.

Current local files show:

• campaign/symphony_9_aliases/meta.txt asks the player to add five aliases: mov, neg, not, movt, and movb;
• campaign/symphony_9_aliases/default.asm uses only those five instructions; and
• campaign/symphony_9_aliases/test.si validates the resulting register values for those instructions.

The older workaround about editing four load/store lines or replacing test.si should be removed for current builds.

Various levels

This section appears to describe older assembly-spec problems.

Current local 2.1.48 Alpha files already ship separate default.isa assets for later Symphony levels, including:

• campaign/symphony_10_stack/default.isa
• campaign/symphony_reg_use_check/default.isa
• campaign/symphony_11_functions/default.isa

These files already include movt, movb, push, pop, call, and ret. The broad regex/workaround section should be treated as historical and should be removed unless someone can still reproduce it on a current build.
