204 • Windows: %APPDATA%\lsnes\lsnes.rc (if %APPDATA% exists)
206 • Unix: $XDG_CONFIG_HOME/lsnes/lsnes.rc (if $XDG_CONFIG_HOME
209 • Unix: $HOME/.config/lsnes/lsnes.rc (if $HOME exists)
211 • All: ./lsnes.rc (fallback default).
213 If leading directories do not exist, attempt to create them is
218 • Commands beginning with '*' invoke the corresponding command
219 without alias expansion.
221 • If command starts with '+' (after possible '*'), the command is
222 executed as-is when button is pressed, and when button is
223 released, it is executed with '+' replaced by '-'.
225 • Commands without '+' execute only on negative edge (release).
229 Settings control various aspects of emulator behaviour.
231 6.1.1 set-setting <setting> <value>
233 Sets setting <setting> to value <value> (may be empty).

249 Keybindings bind commands or aliases to keys (or pseudo-keys).
253 • Do not bind edge active (+/-) commands to keys with modifiers,
254 that won't work right!
256 • Names of keys and modifiers are platform-dependent.
258 • Be careful before binding pseudo-keys (such as joystick axes,
259 buttons or hats) with modifiers. That may or may not work
262 6.2.1 bind-key [<mod>/<modmask>] <key> <command>
264 Bind <command> to key <key> (activating if modifiers in <modmask>
265 (comma-seperated list) are set as <mod> (comma-seperated list).
267 The names of keys and modifiers are platform-dependent.
269 6.2.2 unbind-key [<mod>/<modmask>] <key>
271 Unbind command from <key> (with specified <mod> and <modmask>).
273 6.2.3 set-axis <axis> [disabled | axis | axis-inverse |
274 pressure0- | pressure0+ | pressure-0 | pressure-+ | pressure+0

288 • pressure0+: Pressure sensitive. Released at 0, pressed at +.
290 • pressure-0: Pressure sensitive. Released at -, pressed at 0.
292 • pressure-+: Pressure sensitive. Released at -, pressed at +.
294 • pressure+0: Pressure sensitive. Released at +, pressed at 0.
296 • pressure+-: Pressure sensitive. Released at +, pressed at -.
298 • minus=<val>: Calibration at extreme minus position
301 • zero=<val>: Calibration at neutral position (-32768-32767)
303 • plus=<val>: Calibration at extreme plus position (-32768-32767)
305 • tolerance=<value>: Center band tolerance (0<x<1). The smaller
306 the value, the more sensitive the control is.
310 Print all key bindings in effect.
314 Aliases bind command to sequence of commands. After alias has
315 been defined, it replaces the command it shadows.
319 • You can't alias command to itself.
321 • Aliases starting with +/- are edge active just like ordinary
322 commands starting with +/-.
324 • One command can be aliased to multiple commands.
326 6.3.1 alias-command <command> <expansion>
328 Append <expansion> to alias <command>. If alias does not already
329 exist, it is created.

2189 Memory watch expressions are in RPN (Reverse Polish Notation). At
2190 the end of expression, the top entry on stack is taken as the
2195 • Evaluation order is strictly left to right.
2197 • a is the entry on top of stack
2199 • b is the entry immediately below top of stack
2201 • ; separates values to be pushed (no intermediate pop).
2203 • After end of element, all used stack slots are popped and all
2206 • When pushing multiple values, the pushes occur in order shown.
2208 The following operators are available:
2222 • b : read_signed_byte(a)
2226 • d : read_signed_dword(a)
2228 • i : quotent(a / b)
2233 • q : read_signed_qword(a)
2243 • w : read_signed_word(a)
2247 • B : read_unsigned_byte(a)
2249 • C<number>z : Push number <number> to stack.
2251 • D : read_unsigned_dword(a)
2253 • C0x<number>z : Push number <number> (hexadecimal) to stack.
2255 • H<digit> : Set hexadecimal mode with specified number of digits
2256 (use A-G for 10-16 digits).
2258 • Q : read_unsigned_qword(a)
2260 • R<digit> : round a to <digit> digits.
2262 • W : read_unsigned_word(a)
2266 C0x007e0878zWC0x007e002czW-
2268 1. Push value 0x7e0878 on top of stack (C0x007e0878z).
2270 2. Pop the value on top of stack (0x7e0878), read word value at
2271 that address and push the result,call it x1 (W).
2273 3. Push value 0x7e002c on top of stack (C0x007e002cz).
2275 4. Pop the value on top of stack (0x7e002c), read word value at
2276 that address and push the result,call it x2 (W).
2278 5. Pop the two top numbers on stack, x1 and x2, substract x1 from
2279 x2 and push x2 - x1 (-).
2281 6. Since the expression ends, the final memory watch result is
2282 the top one on stack, which is x2 - x1.

2621 Contains textual base-10 rerecord count (as one line; emulator
2622 just writes this, it doesn't read it) + 1.
2624 12.23 Member: rrdata
2626 This member stores set of load IDs. There is one load ID per
2627 rerecord (plus one corresponding to start of project).
2629 • This member constists of concatenation of records
2631 • Each record is 2-36 bytes long and can represent 1-16,843,009
2634 • IDs are interpretted as 256-bit big-endian integers with
2637 • Initial predicted ID is all zeroes.
2639 Format of each record is:
2641 • 1 byte: Opcode byte. Bits 0-4 are prefix length (prefixlen),
2642 bits 5-6 are count length (countlen). Bit 7 is unused.
2644 • 32-prefixlen bytes of ID.
2646 • countlen bytes of big-endian count (count).
2648 Records are processed as follows:
2650 • To form the first ID encoded by record, take the first
2651 prefixlen bytes predicted ID and append the read ID value to
2652 it. The result is the first ID encoded.
2654 • If countlen is 0, record encodes 1 ID.
2656 • If countlen is 1, record encodes 2+count IDs.
2658 • If countlen is 2, record encodes 258+count IDs.
2660 • If countlen is 3, record encodes 65794+count IDs.
2662 • The new predicted ID is the next ID after last one encoded by
2665 The number of rerecords + 1 is equal to the sum of number of IDs
2666 encoded by all records.

2688 13 lsvs file format (commentary tracks)
2692 • Each cluster is 8kB (8192 bytes) in size.
2694 • Cluster n starts at offset 8192*n in file.
2696 • The following clusters are system special:
2698 – Cluster 0 and all clusters with number multiple of 2048
2701 – Cluster 1 (superblock)
2705 • The cluster table describing cluster n is stored in cluster n &
2706 ~0x7FF (zero last 11 bits of n).
2708 • This cluster table consists of 2048 4-byte big-endian integers.
2710 • Each entry describes a cluster in 16MB supercluster, in order.
2712 • The valid values for entries are:
2714 – 0x00000000: Free cluster
2716 – 0x00000001: Last cluster in chain.
2718 – 0xFFFFFFFF: System cluster (cluster tables and superblock)
2720 – (anything else): Number of next cluster in chain. Must not be
2723 • Due to limitations of the format, there can be at most 2097052
2724 superclusters, giving maximum file size of 16TB.
2728 • The stream table chain always starts in cluster 2.
2730 • Otherwise, it follows normal chaining.
2732 • The stream table consists of 16-byte entries:
2734 – The first 8 bytes of entry give big-endian beginning position
2735 of stream in units of 1/48000 s.
2737 – The next 4 bytes of entry give big-endian beginning cluster
2738 for control data. 0 here marks the entry as not present.
2740 – The last 4 bytes of entry give big-endian beginning cluster
2743 • Stream table clusters are normal clusters, following normal
2746 • The stream begnning position is not guarenteed unique. There
2747 can be multiple streams with the same starting position in the
2750 13.4 Stream control data
2752 • The stream control data consists of entries 4 bytes each:
2754 – The first 2 bytes of entry gives big-endian length of packet
2756 – The next byte of entry gives audio length of packet in units
2759 – The last byte is control byte.
2761 ∗ 0 means this entry is not present and the control data
2764 ∗ 1 is valid control entry.
2766 • The stream control data can also end by running into end of the
2769 – This happens if there happens to be exact multiple of 2048
2770 packets in stream and number of packets is nonzero.
2772 • These clusters follow normal chaining.
2774 13.5 Stream codec data
2776 • Stream codec data consists of raw Opus data packets packed back
2777 to back with nothing in between.

2879 16 Quick'n'dirty encode guide
2881 1. Start the emulator and load the ROM and movie file.
2883 2. Set large AVI option 'set-setting avi-large on'
2885 3. Enable dumping 'dump-avi tmpdump'
2887 4. Unpause and let it run until you want to end dumping.
2889 5. Close the emulator (closing the window is the easiest way). Or
2892 6. For each tmpdump*.avi file created, on command prompt, do
2893 'x264 --crf 10 -o tmpdump_<numbers>.mkv tmpdump_<numbers>.avi'.
2895 7. Do 'sox tmpdump.sox tmpdump.ogg rate -v 32000'
2897 8. Do 'mkvmerge -o tmpdump_video.mkv tmpdump_0000000.mkv +
2898 tmpdump_0000001.mkv + tmpdump_0000002.mkv' (list every
2899 tmpdump_<numbers>.mkv, with + in between).
2901 9. Do 'mkvmerge -o final.mkv tmpdump_video.mkv tmpdump.ogg'. Now
2902 final.mkv contains quick'n'dirty encode.
2904 17 Axis configurations for some gamepad types:
