a6cfe578fb Fix interference audio phase relative to 2A03 2021-08-14 17:23:26 +08:00

a22b17b2c1 Add /A13 and /OE1 audio interference 
In hardware, the audio from the 2A03 APU pins go through an inverted
preamp using one of the 74HCU04 inverter chips in the motherboard.
Though this may be cost-effective on Nintendo's part, the signals on the
hex inverter chip can interfere with one another, especially on the
audio. This can be heard as a buzz or a high pitched whine.

The only known signals to interfere with the audio so far is:
- /A13, the inverted signal of PPU A13 going into the cartridge
   connector.
- /OE1, Output enable for controller reads, though this is only found
   present on the RF Famicom.

8e0816807f Add sprite frame range condition 
A new condition named "spriteFrameRange" is added. It works like frameRange except it follows frame counters assigned to each sprite. Frame counter picks up the nearest frame counter within 6x6 pixels from the last frame and resets if graphics, palette, bg priority or orientation has changed. The condition can by used by sprite tiles only. For example:

<condition>myCondition,spriteFrameRange,301,60
[myCondition]<tile>0,1001,FF0F3600,8,0,1,N

2d0468eff5 HD pack builder and BGM improvement 
Added option in HD pack builder to save screen information when tiles are first shown. User can look up which screen the tiles are added in the tileIndex.csv and open the screen_XXX.csv and screen_XXX.png to see the actual usage of the tiles.

Added playback option and volume option to <bgm> tag. Use 1 for looping playback, 0 for single playback, -1 for no change. Use 0 to 128 for volume control and -1 for no volume change.
