Gameboy Dmg-01 Value Manual Volume ControlEach channel has a length counter that can silence the channel after a preset time, to handle note durations. The squares and noise each have a volume envelope unit to help with fading notes and sound effects, while the wave channel has only limited manual volume control. The first square channel also has an automatic frequency sweep unit to help with sound effects. Each has some kind of frequency (pitch) control.

This is a list of case colors and styles that have been produced for the Game Boy line of handheld systems since 1989. Great collectors piece, and it will only increase in value as the years go on.Gameboy Model Dmg-01 Value. The mixer converts each channel's waveform into an electrical signal and outputs this to the left and/or right channels. The waveform's volume is adjusted and fed to the mixer.

The value written to bits marked with '-' has no effect. Each channel has five logical registers, NRx0-NRx4, though some don't use NRx0. ![]() When a channel is disabled, its volume unit receives 0, otherwise its volume unit receives the output of the waveform generator. The counter can be reloaded at any time.A channel is said to be disabled when the internal enabled flag is clear. Writing a byte to NRx1 loads the counter with 64-data (256-data for wave channel). It contains an internal counter and enabled flag. It is clocked by a 512 Hz timer.A length counter disables a channel when it decrements to zero. Is torrent safe for macThis has a timer, internal enabled flag, and frequency shadow register. Four duty cycles are available, each waveform taking 8 frequency timer clocks to cycle through:The first square channel has a frequency sweep unit, controlled by NR10. If this new volume within the 0 to 15 range, the volume is updated, otherwise it is left unchanged and no further automatic increments/decrements are made to the volume until the channel is triggered again.When the waveform input is zero the envelope outputs zero, otherwise it outputs the current volume.Writing to NRx2 causes obscure effects on the volume that differ on different Game Boy models (see obscure behavior).A square channel's frequency timer period is set to (2048-frequency)*4. When the timer generates a clock and the envelope period is not zero, a new volume is calculated by adding or subtracting (as set by NRx2) one from the current volume. If it becomes zero, the channel is disabled.A volume envelope has a volume counter and an internal timer clocked at 64 Hz by the frame sequencer. When clocked while enabled by NRx4 and the counter is not zero, it is decremented. If the new frequency is 2047 or less and the sweep shift is not zero, this new frequency is written back to the shadow frequency and square 1's frequency in NR13 and NR14, then frequency calculation and overflow check are run AGAIN immediately using this new value, but this second new frequency is not written back.Square 1's frequency can be modified via NR13 and NR14 while sweep is active, but the shadow frequency won't be affected so the next time the sweep updates the channel's frequency this modification will be lost.The noise channel's frequency timer period is set by a base divisor shifted left some number of bits.The linear feedback shift register (LFSR) generates a pseudo-random bit sequence. When it generates a clock and the sweep's internal enabled flag is set and the sweep period is not zero, a new frequency is calculated and the overflow check is performed. What is done with this new frequency depends on the context.The overflow check simply calculates the new frequency and if this is greater than 2047, square 1 is disabled.The sweep timer is clocked at 128 Hz by the frame sequencer. If the sweep shift is non-zero, frequency calculation and the overflow check are performed immediately.Frequency calculation consists of taking the value in the frequency shadow register, shifting it right by sweep shift, optionally negating the value, and summing this with the frequency shadow register to produce a new frequency. The internal enabled flag is set if either the sweep period or shift are non-zero, cleared otherwise. Square 1's frequency is copied to the shadow register. The waveform output is bit 0 of the LFSR, INVERTED.The wave channel plays a 32-entry wave table made up of 4-bit samples. If width mode is 1 (NR43), the XOR result is ALSO put into bit 6 AFTER the shift, resulting in a 7-bit LFSR. When clocked by the frequency timer, the low two bits (0 and 1) are XORed, all bits are shifted right by one, and the result of the XOR is put into the now-empty high bit. ![]()
