For RP2350 VGA or HDMI.
You need to use a local keyboard and set the keyboard repeat as low as possible.
This game was written by CLAUDE 4.6 and took 10 minutes to write with 5 iterations to remove syntax and logical errors.
The obvious update would be to support a gamepad or wii controller - should also be easy enough to port to the Game*Mite and use the buttons.
Not thoroughly tested as I'm crap at games.

Beautiful and sad at the same time. Those who are not ready to use AI can leave.

Edit:
The ball moves smoothly and the angles you can achieve are just as good as on other platforms I've played before. In my opinion, the movement of the racket needs to be improved. The speed is good, I had the patience to finish level 1 with the original settings, but on my second attempt I set the ball speed to 1.2 and the racket to 30.
Tested on the latest RC3 and ILI9341 LCD.

Edit2: Naive question, is it possible to tell this Claude to look into this for example and port it?

Peter,

I had to reconstruct some lines, since in above listing they where cut off.
But after that it runs fine.

I may have to look at integration into the GM menu (i.e. at exit RUN "menu.bas" and not END) and such (select is QUIT, START to start a game).
But it is a nice game. Runs smooth.

Finetuning:
- press SPACE to restart....(space??)
- color Grey does not exist in framebuffer land. Shows as pink.
- next version publish as ZIP (no cut off lines).

Hi Peter,

This is the version you can integrate in Game*Mite 2350 system.

Breakout_GM.zip

Regards,

Volhout

P.S. and now the version that can be played on a RP2040 Game*Mite/Pico Gamer... Especially Geoff's pico gamer has a lot of units sold. But they are all RP2040...Legacy kills...

I could add the TILEMAP command to the RP2040 - no issue, but you would lose 16Kbytes from the A: drive

Hi Peter,

Can I negotiate...Take structures out, put Tilemap in. But this is no cafetaria model I assume...

Sorry, the A: drive is to important for Game*Mite. PicoGamer has 4M/16M flash, so does not bother.

I will think about how it can be done with the feature set of the 2040. Petscii had to prepare an index file, and a binary for flash slot 3. Something along those lines can still be done. But then "the hard way = manually". But maybe that is not even needed. Maybe Sprites can be used for the blocks, and the wall...BOX'es with coordinate collision detect.

matherp said This game was written by CLAUDE 4.6 and took 10 minutes to write with 5 iterations to remove syntax and logical errors.

Are you primarily using Claude online, or are you now using it on the local hardware you said several months ago that you were purchasing?

Peter,

I think RP2040 Breakout game is pretty simple when using SPRITE(B,#n,side) on the ball, and paint all blocks in the background (on F/N).
Now I understand how this works I'll give it a try.

Thanks for implementing the background collision detection.!!

I may have found a way to include TILEMAP in the RP2040 without reducing the A: drive. Watch this space...

Please try this binary with your rp2040 gamemite and breakout. You should have 16Kb more A: drive AND TILEMAP

Peter,

Some dupont wires and a breadboard later...

This works on GM 2040. And indeed there is more A: drive. I have tested breakout, petscii, circle, flappy, SD card, audio (PWM). I have only tested some GM applications.

But it is in essence the microcontroller version. Other features may require additional testing (ADC's, sensors, PWM, UART, PIO, etc.). Any affected ?

Thank you,

Volhout

P.S. 16k more A: drive will fit one game (15k) called Breakout.

The change is a follows:
I'd been frustated that there was extra RAM on the Pico that I couldn't allocate to heap because increasing the heap size increases the program size which given 4 copies (program + 3 flash slots) decreases the A: drive.
In this version I've specified the program size separately from the heap size so heap size has gone up from 128K to 136K, but the maximum program size has reduced from 128K to 120K. Given the VGA versions have only ever had 104K that shouldn't be an issue.
So the firmware has increased by 16K to add the TILEMAP (actually much les than this but it has to be on 16K boundaries) but the program storage has reduced by 4 * 8k. Net change to the A: drive +16K plus 8K extra heap for arrays, framebuffers etc.

Understand.

I did not check, but I assumed you did simply decouple the size of the library/flash slots from the size of the program memory. Since library and flash slots on the VGA version are only 100k, and library/flash slot do not contain editable form of the program they can be smaller.

matherp said I'd been frustated that there was extra RAM on the Pico that I couldn't allocate to heap . . .

Does this change mean there's also more heap on the RP2350?
