Thanks! But the menu is flickering though, its just my TV + camera does a good job of masking it.

Too bad, I was hoping for a possible improvement of the Harmony menu. icon_smile.gif
 

Joystick up/down moves up and down, left/right pages forwards and back, and of course you can use directories to help arrange things.

Yup, that's the bare minimum.

 

But you should consider other controllers or at least allow navigating the menu with the joystick in both ports. And since ROM file names tend to be quite long, IMO you should also think about a way to display the whole filename.

 

Maybe have a look at the Harmony menu and code. And please let me know if you need help there.

 

I love your conversion of Thrust by the way, it is probably my favorite title I played while testing the cart and I'm definitely planning to return to it - I'm sure it is way better than either the ZX Spectrum or Atari 8-bit versions from back in the day.

Thanks a lot! People either love or hate the game. icon_smile.gif

I guess it would take a considerable bit of work, but Eshu's 32 character kernel (http://atariage.com/...r-text-display/) and maybe its DPC+ friends would lend themselves nicely to a improved menu... :P

Just a quick update on the project - after about a week of frustration and bad noises, I got DPC working and Pitfall II now seems to play fine, along with reasonable sounding music. So the cartridge now plays 100% of the 2600's classic library (well, at least until someone testing tells me otherwise).

 

Latest firmware and sources are on github.

Very cool project.  Do you plan to release the PCB design files soon? I'm not wanting to resell, just like to build one for myself.   :)

Have you tried a 64k rom like zippy the porkupine. Sometimes 64k roms can be a real pain.

Yes, it seems to run fine (I only played it for a bit). The cart supports ROMs up to 64k.

I haven't released the PCB files yet since I had wanted to produce some carts myself, to recoup my development costs. Although I'm doing this for fun as a hobby project, it's nice to at least cover my costs, or even better - earn a bit of money to sink into my next hardware project :).

 

You can build the project yourself right now, with a ST32F407 Discovery board. I'm going to get some more PCBs made once I hear back from the various people that I've sent carts to for testing. I'll post here when they arrive, so get in touch then if you want a bare PCB or a built board?

100% agree with you.  That's how I handle a lot of my projects.    The discovery board is too clumsy for me.  So I'll wait.  I don't mind PCB assembly etc.  Great project BTW.

Excluding supercharger, if I am not mistaken. But I plan to take a stab at implementing this myself once I get my cartridge (unless you beat me to it) :)

Ah yes, sorry, forgot about supercharger. Would I need to add a audio jack to the PCB?

No, the ROMs have been dumped. So you only have to emulate them correctly.

My PCB has arrived. I have yet to do some more systematic testing of different ROM formats, but it has been working flawlessly so far.
