Here you can find the source code and design documents for the ZX Spectrum game Triblox, as well as a virtual +3 disk that allows you to load and assemble the game yourself.
Source Code
First, the source code comes in three blocks as there was too much code for the Spectrum to load it all at once. The first is CODE.TEX which contains *F instructions which tell the assembler to include OVER.TEX and SOUND.TEX.

Design Documents
These are the original design documents I used when writing the game – they might help you in making sense of the above source code.
Variables
In machine code, variables are just memory locations you use to store some information. They were normally one byte (0 to 255 or -128 to 127) or two bytes long (0 to 65535), but some were flags, in which case just one bit (0 or 1) was used for each flag, and eight could be fitted in one byte. I set the iy register to point at the first variable, so all the variables could be accessed either using iy + the offset to the variable, or the variable’s address (represented in the assembly code with the textual labels given here). The names of the variables and the brief descriptions give a clue to what their purpose is, but in many cases you would need to look at the code closely to see exactly how they are used.
Subroutines
The above code makes major use of subroutines, mainly to break the code into modules with names and so make it much easier to write, test and understand. Here is a list of the subroutines and brief descriptions of what they all do. You can find all of these routines in the source code above.
Memory Map and Workspaces
The following document specifies where the data for game is located in memory. First is the graphic that is shown when the game is over, then the large TRIBLOX letters that appear on top of the main menu. Next is the colour data for the high score table, followed by the colours for the large TRIBLOX letters. Levnum are the large numbers indicating which level you are on. Cset is the character set used in Triblox (the default Spectrum one looked a bit clunky). Finally at 59,000 are the graphics for the blocks used in the game.
Here we have an explanation of the four main workspaces used in the game. Workspace A holds the graphics for all the blocks that have landed, while C has the colours for the same. Workspaces A and C are copied to B and D every frame of the game, and the moving blocks are added to B and D before they are then copied to the screen.
Here is more detail about workspace C: it is made up of rows of 16 attribute bytes separated by 255 to mark the edge of the play area. All the checks of whether a line has been formed are done using workspace D; as each type of block has a different colour, the colour data alone is sufficient to identify blocks.
Character Set
Triblox did not use a full character set – only the capital letters, nunbers < > and space were defined. As a result, not all characters received their usual ASCII codes, which is why spaces in the textual data within the source code are written with @.
Levels
This shows the speeds of each level, as well as what new kinds of blocks were added (or removed) at each level. The distance between rows of blocks is 16 pixels. Level 1 (that the code actually calls level 0) moves the blocks down in 16 one-pixel increments. On level 2, the speed is doubled, with the blocks moving down in 8 two-pixel increments. By level 6, the blocks move down in six increments, but as 16 doesn’t divide by six, these have to be 3, 3, 2, 3, 3, 2. If you look closely, you can see that the movement is a little bit uneven on some levels.
This describes a feature that I added to try to avoid players becoming frustrated. You won’t advance to a higher level unless there are 20 or fewer blocks on the screen. This is supposed to prevent what can be an annoying situation of advancing to a harder level when the blocks are already piled high, which will usually result in you losing very quickly. In practice though, this means that you can get a really high score by keeping at least 20 blocks on the screen and playing for a very long time on a lower level. If I wrote Triblox again I would take this out.
Screen Layouts and Memory Maps
This diagram shows the layout of the left hand panel, and the address of each part in memory.
This shows the same for the right hand panel. Incidentally, the next blocks indicator was only added to use up what was otherwise redundant space.
Here is the memory map and layout for the main menu.
And here is the same for the redefine keys page.
This is the layout for the high score table (this time with no memory locations indicated).
And finally, the same for the game completed screen. Whether anyone except me has ever seen this is questionable, as the last couple of levels are very very hard. I once managed to complete the game, but only by using the built-in cheat mode (yes there is one – can you find in the source code above?) to start on the last level.
The Source Code on a Spectrum +3 Disk
Below you can down load a .dsk file containing the Triblox source code as .TEX files as well as the game itself. You should be able to use this with any Spectrum emulator that supports +3 disks – I recommend the excellent (and free) Fuse.
To use this virtual disk, first put Fuse into +3 mode (Machine–>Select–>Spectrum +3) then open it using the Media menu (Media–>Disk–>+3–>Drive A:–>Insert…). Next go into +3 Basic (down arrow and enter) and type cat to see what is on the disk. If you type load”triblox” the game will load from disk just as it would have on a real Spectrum. (Use control and p to get “) Besides the source code, there are three other files on the disk. WHOLE is the loader screen – try Load”whole”screen$. CODE1 is the assembled version of the source code above, while CODE2 is graphics data as specified above in Memory Map and Workspaces.
Assembling the Code Yourself
If you would like to assemble the code yourself, you will need HiSoft’s Devpac GENP3 assembler. This was reputed to be the best assembler for the Spectrum – though not the one professionals used. I understand that most Spectrum games were actually written on much more powerful computers with better software. GENP3 is the version for the Spectrum +3, and I used the GENP351 variant which had 51 columns of text across the screen instead of the Spectrum’s usual 32. You can download a snapshot of the Spectrum with GENP351 already loaded and running below.
You can load this into Fuse using File–>Open… – this way the Triblox disk should also remain open. If you now type H, GENP351 will give you some (very brief) help. You can also type B to return to BASIC. GENP351 can be loaded anywhere in memory that there is free space – the version above is loaded to address 25,000, so if you exit in this way you can return to the GENP351 by typing RANDOMIZE USR 25000.
To load the code for assembly type: g,,code.tex
You can now list the section of code from, say, line 1 to 100 by typing L1,100
If you just typed L it would list the whole code and you might be waiting a while…
To assemble the code and save it to the ram disk, first type type c and then enter 1000 to set the macro buffer size, and then type a16,5000,m:code1 (Use control and z to get : ).
Assembly will take a couple of minutes. Once it is done, type b to exit GENP351. Now type merge”triblox” – this will load in the Triblox loader program but not run it. Edit the load”code1″ to read load”m:code1″code 25000 so it uses the code you have just assembled and not the code from disk, and also so that it places it at the right point in memory.
Finally type run and Triblox should load and run.
Now why not try making your own modifications to the code?

My first impression of this website is マイク アタマおかしくなっちゃったんじゃないの？ Soon I will decipher all those things…
A very impressive overview of your coding process and software used. Interesting to see your written notes also. I only got so far as a choose your own adventure game, written in BASIC, called Dracula…
