  1. This game seriously kicks so much ass. I purchased it at the MGC and I haven't stopped playing it. Thank you very, very much.
  2. I used a 10uf cap and I cannot believe how pristine the audio is. I'm assuming the hum / whine was from my interesting mod job. hahahaha Both are gone now.
  3. Quadhorn: You my friend are a champion. All it took was that little diagram and I've learned much more than I thought I would. It sounds crystal clear and I swear that aside from the clarity it sounds much, much, fuller. Thank you for taking the time out to help me. I'm sure that this wont be the last time I need it.
  4. Of course I didn't. I have no idea what I'm doing which is why I asked!
  5. I just did what it said so I'm not sure what they are for. I soldered the resistors to the pins as mentioned and connected a wire from that to a 1/4 socket each. No. I'm not completely sure what those do. I tried but how would I connect that correctly? What do they look like? Yes. Here is where I found the mod: http://www94.pair.com/jsoper/2600_stereo.html I have no idea what a "resistor pullup" is and how to find 5v to connect it to. Also I didn't add the .1uf caps it said because I couldn't hear the audio any longer....unless I used the wrong cap? It was big and blue and that is all I know. ahahaha This is kinda what my situation looks like: -/\/\/-- = 1.8K TIA12<---------------- --/\/\/-- ------------|(-------------->Audio R? TIA13<----------------- --/\/\/-- -----------|(-------------->Audio L? I hope this helps.
  6. Hello everyone. This is my first post so please be gentle. Apologies in advance if this has already been touched on. I just modded my 2600 four switch to display composite video and audio for each channel. I have some minor problems however. The video is 100% fantastic. I now cannot live without it. The audio is stable but there is very loud low-end humming and very high pitched noise. The audio is a pretty low volume as well and when turned up it just makes the noise louder as well. I noticed that when the top of the 2600 is off the high pitched noise isn't as loud, it is only when I put the top on. Also, when I put my finger on the ground of the 2600 the humming stops. It should be noted that the humming is still present when I have the power disconnected. I have each of the 1/4 jacks connected to it's own resistor which goes straight to the corresponding audio pin on the chip. Here are my questions: How can I boost the audio signal without boosting the noise? I'd like to hit the problem at it's source instead of raising the volume on the mixer. I'm assuming the high end noise is rf? I tried using a ferrite ring but no luck. Any suggestions? I'm also assuming that the low hum is a ground loop of sorts....but no power is connected. How can I trick my atari into thinking my finger is still on the ground? hahaha Somewhat of a lamer when it comes to circuits so please help out a fellow atari user. btw...Midwest Gaming Classic was very fun this year! Thanks for the memories and the good time!
