Quote from: panzeroceania on March 23, 2010, 07:10:50 AMthought Tiido might find this interesting, this guy claims to have an early Mega Drive 2 that had very few models released and is kind of like a Model 1.5 as far as the internals go, or so he claims, I don't know enough about the hardware to varify this, but I thought I would show you guys.http://retrocopy.com/forumthread/239-2/glitches-and-emulation-errors-in-mega-drive-retrocopy-0720.aspx#post_1520

Quote from: KillingBeans on December 17, 2012, 10:58:18 PMThe pinouts on your board does not match the 2SC945. Are you using a different kind of transistor?
Quote from: Tiido Priimägi on December 09, 2009, 02:00:58 PMThere should be 2x DACs there, LC7883 that is for CDDA(at least in MegaCD2, seems CDX uses something else) and LC78835 that is for PCM chip.You can just put my circuit on top of the 315-5684, the volume levels of all signals are right so no adjustments need to be made, just desolder the chip, get rid of some extra components and those series and parallel capacitors everywhere on the audio lines and you're done.
