Get answers to your questions in our photography forums. However, most developers lacked the resources to properly adjust their games' music from NTSC to PAL, leading to many PAL games sounding slower, slightly lower-pitched, and in some cases, out-of-tune compared to their original NTSC releases. Expert news, reviews and videos of the latest digital cameras, lenses, accessories, and phones. PAL versions of the NES (sold in Europe, Asia, and Australia) used the Ricoh 2A07 or RP2A07 processor, which was a 2A03 with modifications to better suit the 50 Hz vertical refresh rate used in the PAL television standard. Expansion audio capabilities were removed from international NES systems, but can be restored by modifying the expansion port located on the bottom of the system. On Famicom and Dendy systems, expansion sound chips may add their own sound to the output via a pin on the game cartridge. 18:00 UTC Sjostadshallen, Stockholm, Sweden Handbollsligan, Sweden. The output of each channel is mixed non-linearly in their respective APU before being combined. Many developers were unaware of this detail, causing samples to be distorted during playback. An interesting quirk of the DPCM channel is that the bit order is reversed compared to what is normally expected for 1-bit PCM. 3 uses the DPCM channel for simple drum sounds, while Journey to Silius uses it for sampled basslines. While a majority of the NES library used only 4 channels, games later into the NES's life span were able to use the 5th DPCM channel due to cartridge memory expansions becoming cheaper. The first APU contains two general purpose pulse channels with 4 duty cycles, and the second APU contains a Triangle wave generator, an LFSR-based Noise generator, and a 1-bit Delta modulation-encoded PCM (DPCM) channel.

The Ricoh 2A03's sound hardware has 5 channels, separated into two APUs (Audio Processing Units).

It also integrated a programmable sound generator (also known as APU, featuring twenty two memory-mapped I/O registers), rudimentary DMA, and game controller polling. The Ricoh 2A03 contained a second sourced MOS Technology 6502 core, modified to disable the 6502's binary-coded decimal mode (possibly to avoid a MOS Technology patent ).
