Better sound you could probably do by generating PCM and feeding it into the 2612's PCM line. know what the max throughput is exactly. IIRC the cartridge port has an analog audio input (can't remember if it's mono or stereo though) so it should be possible to generate CD quality audio using hardwar...

Found a YM2608 japanese datasheet. I suppose this should be nearer to the YM2612 than the YM3438. Most of the timing details are the same, but there are different diagrams for FM, SSG and ADPCM reads/writes. Also it looks like there are no restrictions on consecutive reads/writes. Too bad it's japan...

By the way, is there any timing information on the chip? How much time do I have to assert the IC signal to reset the chip? And the same about CE, RD WR and data (D0~D7) signals. EDIT: I'm browsing an YM3438 japanese datasheet. Assuming timing is the same for YM2612, to write data I have to: 1.- Wri...

I have never touched it while working in the MD, so I don't know. As I was not driving CE, RD and WR signals, I suspect maybe all of them could be active, and I'm wondering if this could cause trouble. I want to write code to initialize the chip and set these signals to disabled state ('1'). Unfortu...

I have started experimenting with the YM2612. So far I have only connected power and GND pins to 5V, and the buses (D0~D7, A0, A1, CS, RD, WR, IC) to GPIO pins in the Stellaris Launchpad. These pins are not configured (so right now they are HighZ). I have neither connected the 7,67 MHz clock to the ...

Thanks for the replies! "periodic" mode on the noise channel has 6.66...% duty cycle rather than 6.25% which is pretty noticable. White noise is not really different audibly from the shorter register. Is it really that noticeable? Is "periodic" noise often used for game tunes? (I don't care if it is...

Hardware VGM player
I was thinking of gluing together an SN76489AN, an YM2612, a microcontroller (something like an MSP430 or a Tiva C if more juice is needed), an SD slot and some batteries to make a (kind of) portable Genesis VGM files player. I have started reading VGM files documentation and also some info about SN...
