@Dwedit That's a really clever trick using the top of the stack like that.

I think 6 bytes in not enough for an active object/enemy. Where will you store his type? Health/hit count? Animation frame? Fractional coordinate? Speed? Type is stored in the state, as is animation frames. Fractional coors could be stored as fixed point in the x,y words. Speed is built into the st...

I don't have a lot of NES dev experience, but on other platforms I often implement patterned baddies as an FSM for the patterns with a counter/timer for states that need tweening. What about something like: byte 0 b0-6 pattern state (init,chase,jump,explode,etc.) b7 is the baddie active byte 1 count...

I just built a cable tonight and got the tone.bin to execute.
Pretty cool stuff! :D I'd be happy to test out the RPC code.

Ok.. this is probably a dumb question.

I'm trying to build this from blargg's blog.

What is D0? Is it the same as the yellow 'DATA' line? Do I just leave clock and strobe open?

As an option, Sparkfun has a breakout board for the FT232RL chip (USB-Serial). More of a direct shot and it's only $15.

Very nice work on the bootloader, Blargg. And I really like the idea of supporting a developer and getting a game and a programmable cart. Is it possible to have a second stage boot loader that writes directly to CHR-RAM? If so, something 'official' would be nice. That way you could write little ram...

Hi juef, seems like that is a bug, and I've added it to my list, but wouldn't it be more proper to write a new playlist (plst) chunk instead of zeroing out the lengths of the songs?

Seems this is a long standing issue with swfobject. See here: http://code.google.com/p/swfobject/issues/detail?id=66 I'm not sure how you're using FlashNSF, but if you are just typing in filenames, you can work around this by using %26 instead of &. For instance, say you have this&that.nsf, ...

That's strange. I supposedly don't have to do any initializations since Flash does it for you. Do any other dynamic sound projects work for you? Like this one: http://www.adobe.com/devnet/flash/artic ... index.html

This has either been done, or is planned, depending on what you mean. :) You currently can switch between the different tracks in a single NSF/NSFE, and automatically moving to the next track is supported. However, if you mean having a playlist of several NSF's that you can switch between, that's on...
