Well, the A/D converters for the paddles are actually on the SID chip. Because the paddles are a ramped value generated from an analogue pot they need that electronics to function . SO I would assume that it has something to do with your sid revision. I can almost bet that if you tried it on another revision of the SID it would be fine.
Are you paddles working perfectly? If not it could be something shorting out inside one of them. Which is scary because the SID is a very fragile chip!
looks really awesome, 2600 music carts are coming true
any RSS or DEVblog people can subscribe to?
That part might come later! Sure - you could do a single tune with multi tracks in a row at the moment - but in 4kb you don't have that much memory. Although we are looking at throwing together a bank switch loader - the only problem being you'd have to restart the Atari for every track. The revised playcode / bank switch thing will be coming later once a friend of mine (who is a massive macro asm head) figures out more of how the 2600 ticks.
Ah cool! I wasn't sure if you were ever going to release this. Glad it's going to see the light of day
Yeah - talking of which my half modded Atari 2600 with the awesome composite out is still at your place!! Must come around and finish it soon mate. Really need something better than an RF out!!!

Nup. There is no real point. My work on this is usually when I have time and I just do a 20 hour block in a row on it. It's not something I have the time to continually work at. That said, it's my priority for this month (along side mixing a friends release) and I plan on progressing it to a working version by mid May / start June. So I'll just post stuff up on this thread as I go!
Also are there plugins available for Protracker at all?
Arguably powerpacker (or the like) are libraries that Protracker can use to compress / decompress MOD files a bit like a ZIP, but that's about it for additional functionality as far as I know.
systmcrsh: THANKS MAN! Will have to FINALLY put Octamed back on my 1200 (with the 040) :-)
I've written a program for easily writing music for the Atari 2600. Sort of.
It actually runs on the PC side and isn't "stand-alone" in that you have to also install MODPlug (if you want real-time preview), an emulator to test binaries and some additional asm libraries / compiler. The install instructions will be very clear but they will need to be followed with everything in the same directory. Once you've set this folder up, you can technically copy it to someone else and it will just work. (I just can't officially distrib everything in one folder!)
I'm still working on the tool at the moment. For instance it doesn't have a "load" and "save" feature at the moment because I'm still confirming what is in memory! It will be a single EXE file - no install required - around 40kb and run on Win 95, 98, XP,Vista and 7. Takes about 2 seconds to load on a Pentium 90mhz w/ 16MB RAM. Or 0.2 of a second to load on anything made after 2005. No Mac support but runs on Virtualbox fine.
At the moment I'm adding support for triplet time. This is the first thing I realized I wanted when I tried to make a tune run at an "in-between" tempo! I'm looking at releasing it in late May "as-is" on the logic that if it works for me, it should work for others. Every 3 months or so I might try to implement requested features. For those who have a Harmony cart, it has a "direct to SD" feature which means after previewing you can press a single button which compiles the BIN and pops it on an SD card for preview on the real hardware within seconds.
This is a tool for compiling binaries that run on real systems with real carts. It also supports 4kb EPROMs :-)
Plan for the long term:
- tune "memory optimizer" to allow longer songs (although you can do this yourself in the ASM window)
- support for putting graphics / logo on the screen (first instance will be 1-bit)
- bank switching support allowing up to 8 songs to be put on one cart with own artwork
- potentially add a live mode to hold patterns in a loop and move between sections with synthcart controller.
(all the long term stuff could be 2012ish. Depends when I release an Atari music cart to when I make the software!)
While it might look a little complex, it's actually piss easy to use. In fact, you don't have to touch a single setting if you don't want to - you can just put notes in, punch in an order and press "compile song".
Just letting you know it's coming soon!!
Wow, that is so easy. So little code for the output.
ascii: You obviously have never coded anything closer to the machine language side of things! I'd expect that game to be about 10-15 pages of macro-asm.
Looks like one of the contacts is not connecting correctly. Synthcart is a little picky.
Only $7?!! Man - thats cheap! Ahab great fun and both top dudes (10k and I played with them in NZ).
FFFFFFFFUUUUUUUUUUUUUUUU- 21+? Is there any way I can get in or am I screwed
Fuck your legal age America.
I'll pretend to be your Dad?
Am I too late? Been working on stuff instead of following the forums!
ps. In case anyone is interested.... this is what I've been workin' on. Uses some new software I've written which generates Atari 2600 4kb EPROM images from a tracker-ish interface. This EPROM can then be "burnt" onto a chip, slotted into a cartridge, and put into any Atari 2600. The 2600 only has two "out-of-tune" oscillators with 9 or so limited waveforms, so melody is tricky!! Still in early development stage (working on fast waveform flipping atm) but hopefully MAY have a track + a modded Atari ready for blip ;-)
Greets to all! I certainly am looking forward to the after and pre shows. It was so rad to meet everyone last time even though I couldn't remember names!! This coordination thing sounds like a plan - more to the point, it'd be good to do some meet up's before hand to grab dinner, etc. It's a great opportunity for some of us to catch up in and around gigs. Oh, and I neglected to point out the obvious : I'll be coming to Blip '11 and bringing a DMG or two just in case... :-]
Herr_prof's link is a good one. The 2600 TIA chip is certainly a wild beast to tame. And even when you've figured out what you can do with it (in a way that keeps you sane) it's still hilariously out of tune and out of control. That's my experience anyway!! I have a PC tracker solution for it which semi-simulates what's going to happen, but you don't exactly know until you hit "compile" and put the binary to an EPROM. My link software (which goes between the tracker and the asm code) is barely working but does enough that i can just hack test files together. Once my harmony cart arrives I'll hopefully get slightly further with dev and might be able to share it later in the year :-] At the moment, it's all about fast wave switching and stupidly fast tempos... (and short optimized breaks tunes)

Would this work? Also will a cynthcart work without a monitor? Like just a c64 plugged into a mixer
No, that won't work. That's 5 pin din for old hifi equipment from the 70's / 80's.... you need an 8 pin DIN socket which splits to Composite, Y/C (hint, solder this to an SVideo socket for amazing pictures!!) and your audio :-)
Just a note that C64's are VERY sensitive to having their cables shorted out. NEVER hotplug a C64 with the power turned on and ALWAYS be very careful that you plug it into a mixer with the power turned off. I've blown up 2 SID chips now - first was from the one time I hot plugged it, and the other was using my 8xxx series SID with a valve preamp. Apparently there was some back voltage though the pre when the power was turned on (and that's an Avalon unit too)
"oxygenspa"
"knit city"
"task80"
"sabrepause"
Awesome :-]-<
I reakon this is going to be mega.
Hell yes. SB8 here we come!
