| =====Play Music/Looping SFX/Second Engine Control (Command <tt>$00-$FE</tt>)=====
| |
| <u>Input</u> <pre>%xyyyzaaa</pre>
| |
| <u>Output</u> <pre>%00000aaa</pre>
| |
| * <tt>x</tt>, when set, fades out the music over 84 tempo ticks. It causes music VCMD <tt>$F5</tt> (echo enable bits and volume) to effectively act as a NOP when this happens.
| |
| * <tt>yyy</tt> is a looping SFX ID for channel 6, with a range of <tt>%001($1)</tt>-<tt>%100($4)</tt>, and looping back to <tt>$1</tt> after <tt>$4</tt>. Except for <tt>$3</tt>, they also don't restore the instrument ID after playing them.
| |
| * <tt>z</tt>, when set, causes the BRR engine noise generator from $2143/$F7 to output on channels 4-7.
| |
| * <tt>aaa</tt> is a music ID that is output to the SNES via $2140. <tt>%110($6)</tt> is a special case, as it utilizes an ID that is defined via loading a single byte to a specific memory location, rather than its own (the ID itself is illegal if forced due to a zero pointer). Music data does not actually need to be loaded in this particular case, as it is all stored in one go.
| |
| | |
| =====Load New Data (Command <tt>$FF</tt>)=====
| |
| Loads new data when set to <tt>$FF</tt>. See [[N-SPC_Engine#Load_New_Data_.28Command_.24FF.29|the source build's Load New Data command]] for the loading protocol, as it is identical binary-wise to the copy used in this one minus the *Ver S1.20* string.
| |
| | |
| ====CPUIO1 ($2141/$F5)====
| |
| <u>Input</u> <pre>%xyzzzzzz</pre>
| |
| <u>Output</u> <pre>%00zzzzzz</pre>
| |
| * <tt>x</tt> increases the overall BRR engine noise generator frequency on channel 8. The BRR engine noise generator frequency is designed to hiccup like a gearshift when activating.
| |
| * <tt>y</tt> plays a continuous beeping tone on channel 6... unless the music that's currently playing is <tt>$11</tt>, which means a different SFX plays on channels 6 and 8.
| |
| * <tt>zzzzzz</tt> controls the BRR engine noise generator frequency on channel 8. Disable with zero. This value is what is output to the SNES via $2141.
| |
| | |
| ====CPUIO2 ($2142/$F6)====
| |
| <pre>%xyzzaaaa</pre>
| |
| The value output to the SNES via $2142 is which bits are being utilized to play the SFX. Higher bits have more priority, but CPUIO0's channel 6 SFX has higher priority, which in turn is out-prioritized by CPUIO1's channel 6 SFX.
| |
| * <tt>x</tt> stops the music and goes '''BOOM!''' Channels 3-8 are used, with 5-8 being continuously used afterwards.
| |
| * <tt>y</tt> plays a UFO-like SFX on channel 6.
| |
| * <tt>zz</tt> controls the BRR engine noise with vibrato on channel 6.
| |
| * <tt>aaaa</tt> controls incidental SFX on channel 6. <tt>$4</tt> doesn't play anthing, and the values wrap around to <tt>$1</tt> after <tt>$8</tt>, except for $C, which plays <tt>$8</tt>.
| |
| | |
| ====CPUIO3 ($2143/$F7)====
| |
| <u>Input</u> <pre>%xxxxyyyy</pre>
| |
| <u>Output</u> <pre>%0000xxxx</pre>
| |
| *<tt>xxxx</tt> controls the panning of the second vehicle on channel 7, with zero representing left and $E representing right. Sets up a whole bunch of vehicle noises on channels 4-7 if set to $F instead that are not pitch-controllable. These bits are output to the SNES via $2143 as the lowest four bits.
| |
| *<tt>yyyy</tt> controls the BRR engine noise generator frequency (and volume) of the second vehicle on channel 7, or several at once on channels 1-5 and 7 if bit <tt>z</tt> on $2140/$F4 is set.
| |
| | |
| ====SFX Sequence Format====
| |
| Most of the SFX is hard-coded and the instrument format, when utilized outside of the actual instrument table, is identical to a music instrument's. The only SFX that actually uses a SFX sequence format beyond an array of notes is CPUIO0's bit <tt>yyy</tt> ID <tt>%010 ($2)</tt> (there's actually a second one defined, but it appears to never have been used).
| |
| | |
| ''TODO SFX sequence format (roughly the same as the Prototype variant, except with different supported VCMDs and with VCMD $FF doing the same thing as Pilotwings: restarting the SFX)''
