[Code for reading 5200 joysticks]

Thanks, that helps.

 

I'm trying to read KBCODE to get the keypad numbers by polling it in a loop. In MAME the numbers  keys register, but on real hardware it remains zero.  (it doesn't work in Altirra either)

 

Is there a technique with reading KBCODE? Something I have to do first like writing to CONSOL or a timing requirement as with reading POT?

How do I read the number buttons and start/pause/reset buttons on the joystick?

[Code for reading 5200 joysticks]

Thanks, that was it. The below code works:

 

void main()
{
    for(;;) {

        u8 *ptr;

        ptr = (void*)0xE800;    // POKEY Pot
        PrintNumber(12,0,*ptr++);
        PrintNumber(12,1,*ptr++);

        ptr = (void*)0xC010;   // Trigger (fire buttons)
        PrintNumber(8,0,*ptr++);
        PrintNumber(8,1,*ptr++);

        ptr = (void*)0xE80B;   // POTGO start scan sequence
        *ptr = 0x00;
        ptr = (void*)0xE80F;   // SKStat Fast pot scan
        *ptr = 0xff;
        
        for(int wait = 0; wait < 30000; wait++);
    }
}

 

I had to trigger the POTGO and enable the Fast POT scan, along with a delay between reads.

for information on POTGO and SKSTAT.

 

This assumes the interrupts are disabled, or the interrupt vectors have been overridden.

 

[Code for reading 5200 joysticks]

I'm trying to write code for reading 5200 joysticks. My code is simply:

 

void main() {

    for(;;) {

        uint8_t *ptr = (void*)0xE800;
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
        PrintNumber(12,y,*ptr++);
    }
}

 

I've tried on MAME and Atari 800 and it's only returning 0. If I set the address to 0xC010 the triggers return 1 or 0, so I know the code can read and display values.

 

Any ideas on what I could be doing wrong? Do I have to set up the POKEY in some way for this to work?

For now, send me a PM if you need any. These are fully assembled, without shells. They're easily programmable and reprogrammable with an EPROM programmer. International shipping is fine.

Are the shells the standard ColecoVision cartridge size? Is there a 3d model for them? Getting the shells 3d printed appears to be fairly expensive.

[ColecoVision MegaCart FAQ]

Thanks, that's great. How about shells/casings? How do I get those?

[ColecoVision MegaCart FAQ]

How do I order them? Do you have a website with the details? Do you supply just the PCBs or do they come complete with the components and casings? Do you ship internationally?

 

[ColecoVision MegaCart FAQ]

Am I able to buy megacarts? Who sells them, and how much do they cost?

Thanks again for all your testing. I've increased the debouncing delay by a tick. Let me know if it's better.

Another fix, I left in the too long delay I was using for testing.

 

Once we're happy these are fixed, I'll release my other games with this fixed in them as well.

Thanks again for your feedback. It was very helpful. Could you try these for me? Let me know if it's still not right. I'm happy to keep iterating until it works properly.

One thing though is that in Vexed the cursor moves really fast sometimes making single cell movements very difficult, possibly oversensitive to the joystick?

Can you try these? I've upped the first move delay a little, but if it's not enough I can increase it.

One question about Diamond Dash 2: You say each level has 5 difficulties, but can these be selected like the individual levels, up to Level O can? I couldn't figure out what "5 levels of difficulty" means? Please explain, if you have time.

Sorry, that text shouldn't be there. That's an old entry based on an old plan that I mistakenly left in the text.

[New Game: Diamond Dash 2]

Can you give these a try? I've fixed a number of issues in my libraries since I released these, and hopefully that'll fix the problems you're seeing.

 

Please let me know if there's still an issue and I'll look into it.

I know how it was. You had your faithful ColecoVision, but your best friend had a C64. He loved to rub your nose into the fact he had the latest puzzle game and you didn't. You loved your ColecoVision, but you just wished they'd released a new game for it. Well, here it is finally, 36 years too late.

 

    

 

    

 

Collect the coins, avoid the boulders, fireflies and butterflies. Amoebas and Magic Walls make diamonds too.

Can you clear all the tiles?

No problem. I wasn't happy with the controls either. Anyway I was only porting Arno Dash to ZX Spectrum, so not interrupting anything important.

[New Game: Pillars]

I've increased the delay slightly and fixed a few issues on the key repeat delay. Let me know if what you think. I'm happy to keep tweaking until it feels right.

I've fixed the issues you've mentioned:

 - Make sure sound is turned off after finishing

 - Fixed rendering text on finishing

 - Made # key resigned game

 

I prefer to make games intuitive than to have instructions, though maybe that's a bit difficult for a console. It's reasonable idea,maybe next release.

 

The features you've mentioned are good idea. Originally, I didn't have enough tiles for extra text, but I might just have enough now to display numbers.

 

Maybe in a later version I'll add a timer and some stack options.
