cynthcart website says cynthcart 2.0 carts will be released may 2016. You can download it now though.
According to the FAQ on the cynthcart site, cynthcart 2.0 uses the second sid at $D420 (same as kerberos cart). So If I understand correctly, it's the cynthcart 1.2 that will break. So really, just re-wire the sid2sid to be at $D420 and everything will work besides cynthcart 1.2. As for where to wire the SID2SID, no idea.
Pin 2 on the monitor output jack gives a B&W composite. Wire it to an RCA cable where Pin 2 goes to tip and pin 13 goes to the ring (GND). Also, Pin 1 is audio out, wire it the same way.
At least you can test video and/or audio output and function on it, so the next guy isn't a sucker.
I'm guessing from the solder in the background that this is in your ability!
Thanks for that! I had looked and looked couldn't find a way to test video. It's already gone though, so hopefully the buyer sees this!
Do the lines like flicker, almost like scanlines or something? I backlit my GBA and I get that. There's a pot on the board you can adjust to help it, but mine doesn't seem to do anything.
Just got my carts. They work well! They're exactly as described. I kinda realized that some of the roms I chose might not be as useful as I originally thought, but it's still fun to have and play around with simple tools
Cheers!
Thanks for the update! Glad they got to you safe! If you ever want to re-flash them, I'd be happy to do it. Shipping both ways should be about $6 total.
Just realized I have no idea how to send you a custom rom for my third cart (GB Electric Drum) while ordering, so just ordered 2 carts from the list of roms you had. Also didn't check to see if I was getting flat rate shipping. Woops. Edit: Yeah, I got flat rate. Woot!
Just added the option for a custom ROM! Go ahead and order that one. It will charge you for shipping but I'll refund it. Also, you did not get flat rate shipping!
I think the problem is that if they're different roms selected, paypal thinks it's a completely different product. So that's nice. For now, anyone who wants multiples, just checkout normally and I'll refund you the extra shipping. Thanks!
