VCS Game Maker
This online tool is a no-code environment designed to allow someone to create a game for Atari 2600 without knowing much about programming and without installing anything on their computer.
It uses Blockly to allow the user to implement the logic using blocks and then, behind the scenes, generate a Batari Basic source code, that is then be compiled using batari-basic-js in order to generate an Atari 2600 ROM, which is emulated using Javatari.

You know what would be cool? That the second player doesn't have to be there automatically and a button to make a new project.
Good Ideas! I opened issues on the project page to remind me later:
But do keep in mind, that on the Atari 2600, the second player is often used as an enemy.
The download version is only 0.30.0 Can you please make the 0.32.1 version downloadable?
Okay, I will generate a new downloadable distribution later.
OK, created Win32 distribution for version 0.32.1:

Love this so much, I do GB/C development so seeing Atari get some love is so nice. I wanted to check, is there a Discord or forum where people have gathered around this?
It's always cool to meet other retrodev enthusiasts! 😉
Well, the closest thing would be the AtariAge forums:
https://forums.atariage.com/topic/323059-vcs-game-maker-generate-bbasic-code-with-a-visual-tool/page/5/
Gotcha gotcha! I wanted to check, a lot of the gb studios community is built around it so it might not be a bad idea as development gets further along!
keep on crushing it <3
Thanks! 😉
What if you add TIA Tracker for the music to give a background music for it.
We need a music for it!
Yes, that's kinda planned for the future:
https://github.com/haroldo-ok/vcs-game-maker/issues/65
YEAAAAA
Will there be a way to shift the pixels of a sprite off by a certain amount. As I'd like to further multiplex the way sprites can be manipulated on a horizontal scanline. And with the ability to increase the height. The possibilities could be astounding if pushed further.
Of course take your time and thank you for everything you have done. Once I'm finished with Eternal Memory I'll begin to use this next and create something to showcase the power of this awesome software.
Hello again! Well, at the moment, it's only capable of doing what bBasic's standard kernel can do, so, unfortunately, it probably won't be capable of shifting the pixels per scanline. It doesn't seem that the DPC+ kernel isn't capable of each, either.
Anyway, it will be interesting to see what awesome game you will do next. 😉
Please, keep us updated!
Will do and hey even if we don't have the ability to shift the sprites. The increased sprites height is more than enough for me to do some crazy stuff.
Sorry for snail salt comment i made a few months back
Yes, it's royalty-free! 🙂
i can publish game?
Yes, you can, it's royalty-free. 🙂
i have idea, make it so you can switch from block editing to text editing, and why dosent the background editor take up the whole screen?
Hello,
Converting arbitrary source code back into blocks would be notoriously difficult, but creating full screen modes for the background editor would be doable.

pretty dang good 2600 game maker, I wish there was a hexadecimal like famitracker music maker.
Thanks; that's kinda planned for future implementation:
https://github.com/haroldo-ok/vcs-game-maker/issues/65
Suggestion: Multicolored sprites. I've noticed a lot of home-brew and some Atari 2600 games that have multicolored sprites. Like each line of the character is a different color. Example:
Notice how each line is a different color in the sprite. Maybe to import this function, there could be:
Yeah, when DPC+ support gets implemented, it will have support for multicolored sprites
Nice, thanks! Also found another issue. I was trying to make my new game (GD2600, essentially a port of GD for the VCS) and sometimes when I just moved around the <div> placing block board, the sprites' frames were reset to default and the backgrounds auto-deleted themselves, only remaining the default background. But the code (thankfully) didn't get deleted along with everything else. But I think you should also fix this issue.
Thanks for the bug report.
Okay, I opened the issue to look on that later:
https://github.com/haroldo-ok/vcs-game-maker/issues/135
Okay, one more bug squashed.
Version 0.32.1 fixes a bug where sprite/background edits where being lost if the user changed pages a fraction of a second after editing a sprite or a background.
So this is essentially like Scratch?
Its not the same thing, but it has similarities
Hello Haroldo.
I am writing some texts about Blockly coding and i am taking your work as one of the examples. If you like i will share the text with you. The text speak about how the blockly appears to boost the development. The text are made for a course for App Inventor and describe how the blockly works. I have here my own account. Please write me if you can.
Seems like an interesting idea! Please, go ahead! 😉
Thank you Haroldo-ok for the quick reply.
When i end the texts I promise to send you a copy. In this texts i am trying to develop the idea of coding with blocks in ANY SYSTEM. There are blockly for Java, Python, Lua, Flutter, Micropython, also there are a lot of game engines using this "technique" as Stencil, GameMaker, Godot, etc... And YOU are in this groups. The idea of using blocks it's a great idea, giving the posibility to the people TO THINK in the code, more than (if i make a mistake in the sintaxis? where is the error... i cannot find the error!.
That's the idea.
When i end the text, I promise to send you the pdf and the ppt of the class. (I am Teacher/Developer and.... Geologist too, and many other things too like 8bit computer collector) --->a little bit of everything.
By the way, i am ZX Spectrum programmer, and i have the dream to see the blockly mode into an engine for create ZX Spectrum games.
Again, Thank you for replying so soon.
Many thanks! Sounds like a cool idea! 😉
BTW, there are a few block-based programming languages that generate C code; they could be adapted to support the ZX Spectrum
HAROLDO! I AM YOUR FAN NOW!.
IF YOU CAN.... THIS COULD BE A GREAT IDEA FOR MAKE A NEW ENGINE FOR DEVELOPING GAMES FOR ZX SPECTRUM. Write me if i can collaborate with the project. (i have several ZX Spectrums) CZ Spectrum 48k, Sinclair Spectrum 2000, TK85 (Microdigital). ----> I have many other 8bits computers too, but is not important. Again. Thank you for replying and let me know IF YOU REALLY PLAN TO DO IT, I PROMISE TO HELP IN ANY OF MY POSIBILITIES. (Sorry for my english, i am Spanish talker).
Thanks! I'll take the offer into consideration! 👍

hi how to create a seperate "title screen"/game over screen? I see on collide it can go there but not sure how to make one.. is it a special type o background??
Hello! On the "Event" section, there are the "Change state" and "On ..." components; in order to call the gameover screen, you would change the state to "Game over", and then, thenengine will fire the "Gameover start" event, then start loopi g the "Game over update" event
Here's a more elaborate example. where the game starts on a title screen, until you press a button:
Event.example.vcsgm.zip
thank you that will help!
i was making my game and I placed an empty () x () math block to make a sprite's speed go negative. when I placed the block, the program completely crashed, and I am now not able to use it :< maybe try making so that the emulator only runs when it is told to, not when it detects any sort of click or change
Okay, I opened two issues to look at that later:
https://github.com/haroldo-ok/vcs-game-maker/issues/132
https://github.com/haroldo-ok/vcs-game-maker/issues/133
ok, thanks! also, seems that because i left the tool alone for a while after crashing, it deleted the entire code. i think you should keep that in, but maybe make so that when you open the tool it will make a backup file, make you download your old progress without the () x () or a block that potentially crash the tool, and then you can resume from there. Maybe there could also be a detector for potential crashes that won't run the project but gives the person a warning.
this is so cool! but I have an idea for the Event category:
And what if, in the background category, there was:
And my last idea, for the sprites category:
If possible, could you add these? Thanks ^_^
Nice ideas 😉
how dose the ball function work? i am trying to make a sprite into a ball so it can bounce around the screen is it possible?
Yes, you have to set width and height for the ball, and then control its X/Y positions to make it move around. One of the examples shows how to bounce a ball around.
is it possible to switch colors every scanline with thos? if so, how do i do it?
Unfortunately, for now, the tool does not support that feature, but may implement it when it starts supporting DPC+
ok thank you anyways
also there is a bug that keeps happening when I edit the images where it just doesn't update correctly. other than that the tool is very good.
Must be related to this bug:
https://github.com/haroldo-ok/vcs-game-maker/issues/19
Okay, one more bug squashed.
Version 0.32.1 fixes a bug where sprite/background edits where being lost if the user changed pages a fraction of a second after editing a sprite or a background.
When doing support for other mapper formats. Will the super charger be on that list or is it too low of a priority to even try.
Well, when implementing support for DPC+, it will also be necessary to implement at least partial mapper support.
When we get to have the ability to compose music. Will it be done with the standard detuned tones or will it be a special standard like TItuna or something like DPC+?
As I'd like to have the option to use just use standard kernel for music compositions. So that way CPU time is minimal for music.
I will have to see what to do; generally, I opt for something simple that uses less RAM
https://github.com/haroldo-ok/vcs-game-maker/issues/46
That would be super awesome. As having it be a lean as possible will hopefully allow for some breathing room. And allow me to use more functions of the machine in tandem with the music.
I am so thankful this exists
Thanks! 😉
looks like I've got a special tool to create some new VCS games
Nice!
Good gravy the update feels like a Halloween treat. Thank you so much for the ball update it's a nice upgrade. Also I meant to write this a couple of days ago, but you know how Halloween is and all.
No problem; thanks for the review. 😁
Im so hyped for 0.30
How close is Sprite Height changing?
Unfortunately, I haven't gone back to its implementation since last time; the implementation is there, but the height randomly resets when navigating between screens. I will come back to it, eventually
Oh, that really is weird.
Hello, again; version 0.32.0 adds means for changing the sprite height:

Hello; the downloadable Windows version is currently based on an older version of the tool.
ahh! I figured it was some small discrepancy. ok thanks!
No problem!
can a projectile be like breakout angle vert and horizontal ?
im doing something wrong...
Looking at it, it seems mostly correct, so far, separating the X and Y speed components; changing the "if Ball Y Speed < 2" to "if Ball Y Speed = 1" should work (untested)
this is what i have so far. still just vertical..hmm
Okay, this one shoud work:
Example project: https://github.com/user-attachments/files/17498770/vcs-game-maker.bounce-ball.pr...
yes thanks!!
Made this in 5 minutes as a warmup
Nice! 😉
mayve asked but is there a way to see if player 0 is at x (top of screen) to go to next background/level?
Yes, the level number can be incremented like a variable:
Example project: https://github.com/user-attachments/files/17481907/vcs-game-maker.next-level.exa...
thanks works!
No problem!
Can u add like buttons under the get rom button that can control for the emulator on mobil
Okay; I opened an issue in order to not forget it:
https://github.com/haroldo-ok/vcs-game-maker/issues/121
Ok
Uh
It seems that the code for the "or" operator is being generated incorrectly when inside a repeat block.
I opened the issue: https://github.com/haroldo-ok/vcs-game-maker/issues/119
Oh cool
OK, fixed it: https://haroldo-ok.itch.io/vcs-game-maker/devlog/815804/version-0256-fix-code-ge...
Cool
theres a bug with the collision and or blocks being together
It looks like there's a bug when using a while block inside an if block...
I have opened the relevant issue to look at it later:
https://github.com/haroldo-ok/vcs-game-maker/issues/109
BTW, aside from the code generation bug, there's a chance that the `repeat` block won't work in a useful way with that arrangement:
The way the code above is arranged, it means that it would stop everything else and just keep moving the missile and nothing else, until it collides with something. No joystick input, no movement for the other sprites, just the missile.
There's a good chance that it would probably not be what was intended.
Okay
Fixed the code generation bug: https://haroldo-ok.itch.io/vcs-game-maker/devlog/811947/version-0253-fix-nested-...
Herod fixed it
I'd want to make a more advanced game. But this seems to only handle more simple-looking games.
Yes, because it only supports Batari Basic's standard kernel. Once the tool does every thing it can do for the standard kernel, I intend to implement support for the DPC+ kernel
I'm sure why, but I have a feeling that there is a non-DPC+ multi-sprite kernel somewhere on the AtariAge forums. I just realized this since some DPC+ games are usually underwhelming for something like 32+ KB A2600 rom.
There exists a non-DPC+ multi-sprite kernel, but I opted to skip it, in order to better focus the development of the tool.
Probably for the best...but I do recommend that you use a kernel that is 32KB or lower. Mostly because some kids will use the Atari + platform to test their Atari 2600 games made with this thing.
Okay, thanks for the tip.
If i could I'd donate
No problems, I activated the optional donation button. 😉
Hi there, this looks interesting but i was surprised to not see any tutorials on youtube. how are folks learning how to use this?
Good question! It seems people are kinda figuring out how to use it, but it would definitely be better to have a tutorial available...
Okay, here's a tutorial:
Some of the skills I have are from a mix of assembly and console understanding. And GB studio having a similar "flow" to this.
Yes, I can see the similarities...
I was trying to make a game, but I found some weird glitches:
When I fix the player's sprites, sometimes all the game code gets erased
The sound of the emulator disables itself for no reason
I also have a suggestion:
Make a wait seconds or frames block
Despite these bugs, this is a very impressive tool!
Thanks for the suggestions ! 😉
Okay, opened the issues to look into later.
Make a block for waiting seconds or frames
The sound of the emulator disables itself for no reason
When changing the player's sprites, sometimes all the game code gets erased
Okay, implemented it:
https://haroldo-ok.itch.io/vcs-game-maker/devlog/824048/version-0270-create-bloc...
Yea
Okay, one more bug squashed.
Version 0.32.1 fixes a bug where sprite/background edits where being lost if the user changed pages a fraction of a second after editing a sprite or a background.
Finaly
Pls multiple sprite update pleasss
Once I finish implementing support for the standard kernel, I would intend to skip right to DPC+ 😉
oh cool
