This is a fun side project to emulate the solutions to Zachtronics game "TIS-100."

Get the Windows executable here

To run the emulator, execute TIS100.exe <asm filename> <board filename> from the command line. The expected file formats are explained below.

The .asm file format is essentially the same as used for the save files. The @1 syntax starts a block of code belonging to a specific chip. Then, an @2 line begins the next block, etc.

For example, the following file specifies two chips that will "triplicate" a given input. That is, the input 1, 2, 3 will be expanded into 0, 0, 1; 0, 1, 2; 1, 2, 3.

@1
mov right down
swp
mov acc right
mov acc down
mov up acc
mov acc down
sav

@2
mov 0 left
top:
mov left left
jmp top

Since each level uses a potentially different chip layout, we use the board file to specify which chips are in which positions. Each line represents a chip, and has the following format, with the parts explained below: <name> <x position> <y position> <type>.

• <name> is one of the @1 style names referred to in the .asm file.
• <x position> and <y position> are integers representing the location of the chip. x increases going right across the screen, and y increases going down the screen.
• <type> can be either AssemblyChip or ConsoleChip.
  • AssemblyChip is the TIS-100 programmable assembly chip you are used to.
  • ConsoleChip is a chip specific to this implementation that reads and writes input using the console.

The following board file specifies the chip configuration to make the triplicator code above work as intended.

@1 0 0 AssemblyChip
@2 1 0 AssemblyChip
@3 0 -1 ConsoleChip
@4 0 1 ConsoleChip
