[Tuxnes-devel] Sound

[Paul Z. <pe...@cr...>]

With the release of 0.75 I was taking a look at the sound code today..
and realized that it can't interact properly with the ROMs in realtime.
It is only accurate at 1/60 sec intervals, so any reads from 0x4015 not
immediately after a vsync could be incorrect.

I need titles of games that aren't working properly (could be sound timing
issues with the game reading register 0x4015 or the DMC Interrupt).

I have fixed (I think) on my local copy the sound timing issues
regarding 0x4015 (It renders the sound as the 0x40xx registers are written,
0x4015 is read, or a vsync occurs and sends the audio on vsync).

I *think* TMNT uses sound timing for one of its levels, but I'm not sure
and I'm typing this email as I'm headed out the door..

I'll check in the realtime fix later tonight.
