5 Startup file lsnes.rc

Upon startup, lsnes (lsnes/SDL only) executes file lsnes.rc as 
commands. This file is located in:

• Windows: %APPDATA%\lsnes\lsnes.rc (if %APPDATA% exists)

• Unix: $XDG_CONFIG_HOME/lsnes/lsnes.rc (if $XDG_CONFIG_HOME 
  exists)

• Unix: $HOME/.config/lsnes/lsnes.rc (if $HOME exists)

• All: ./lsnes.rc (fallback default).

If leading directories do not exist, attempt to create them is 
made.

6 Internal commands

• Commands beginning with '*' invoke the corresponding command 
  without alias expansion.

• If command starts with '+' (after possible '*'), the command is 
  executed as-is when button is pressed, and when button is 
  released, it is executed with '+' replaced by '-'.

• Commands without '+' execute only on negative edge (release).

6.1 Settings:

Settings control various aspects of emulator behaviour.

6.1.1 set-setting <setting> <value>

Sets setting <setting> to value <value> (may be empty).

6.1.2 unset-setting <setting>

6.1.3 get-setting <setting>

Read value of setting <setting>

6.1.4 show-settings

Print names and values of all settings.

6.2 Keybindings

Keybindings bind commands or aliases to keys (or pseudo-keys). 

Notes:

• Do not bind edge active (+/-) commands to keys with modifiers, 
  that won't work right!

• Names of keys and modifiers are platform-dependent.

• Be careful before binding pseudo-keys (such as joystick axes, 
  buttons or hats) with modifiers. That may or may not work 
  right.

6.2.1 bind-key [<mod>/<modmask>] <key> <command>

Bind <command> to key <key> (activating if modifiers in <modmask> 
(comma-seperated list) are set as <mod> (comma-seperated list).

The names of keys and modifiers are platform-dependent.

6.2.2 unbind-key [<mod>/<modmask>] <key>

Unbind command from <key> (with specified <mod> and <modmask>).

6.2.3 set-axis <axis> [disabled | axis | axis-inverse | 
  pressure0- | pressure0+ | pressure-0 | pressure-+ | pressure+0 
  | pressure+-] [minus=<val>] [zero=<val>] [plus=<val>] 
  [tolerance=<val>]

Set axis parameters for axis <axis>.

• disabled: Disable axis

• axis: Normal axis

• axis-inverse: Inverse axis

• pressure0-: Pressure sensitive. Released at 0, pressed at -.

• pressure0+: Pressure sensitive. Released at 0, pressed at +.

• pressure-0: Pressure sensitive. Released at -, pressed at 0.

• pressure-+: Pressure sensitive. Released at -, pressed at +.

• pressure+0: Pressure sensitive. Released at +, pressed at 0.

• pressure+-: Pressure sensitive. Released at +, pressed at -.

• minus=<val>: Calibration at extreme minus position 
  (-32768-32767)

• zero=<val>: Calibration at neutral position (-32768-32767)

• plus=<val>: Calibration at extreme plus position (-32768-32767)

• tolerance=<value>: Center band tolerance (0<x<1). The smaller 
  the value, the more sensitive the control is.

6.2.4 show-bindings

Print all key bindings in effect.

6.3 Aliases

Aliases bind command to sequence of commands. After alias has 
been defined, it replaces the command it shadows.

Notes:

• You can't alias command to itself.

• Aliases starting with +/- are edge active just like ordinary 
  commands starting with +/-.

• One command can be aliased to multiple commands.

6.3.1 alias-command <command> <expansion>

Append <expansion> to alias <command>. If alias does not already 
exist, it is created.

6.3.2 unalias-command <command>

Clear alias expansion for <command>.

Print all aliases and their expansions in effect.

6.4 run-script <script>

Run <script> as if commands were entered on the command line.

6.5 Video dumping

Following commands control video dumping:

6.5.1 dump-avi <prefix>

Dump AVI video to prefix <prefix> Notes:

• The codec is Camstudio Codec in gzip mode.

• Encoder and muxer are internal, available on all platforms.

• Audio enable/disable and framerate has no effect.

• The audio dumped to .avi is low-quality version. The 
  high-quality version is dumped to .sox file.

6.5.2 end-avi

End current AVI video dump (closing the emulator also closes the 
dump).

6.5.3 dump-jmd <file>

Dump JMD video to file <file>.

6.5.4 end-jmd

The available element <sizes> are:

• byte: 1 byte

• word: 2 bytes

• dword: 4 bytes

• qword: 8 bytes

When reading RAM and ROM, multi-byte reads/writes are big-endian.

Called when video dump frame is being painted. Any gui.* calls 
requiring graphic context draw on the video.

8.10.3 Callback: on_frame()

Called on each starting whole frame.

8.10.4 Callback: on_startup()

Called when the emulator is starting (lsnes.rc and --run files 
has been run).

8.10.5 Callback: on_pre_load(string name)

Called just before savestate/movie load occurs (note: loads are 
always delayed, so this occurs even when load was initiated by 
lua).

8.10.6 Callback: on_err_load(string name)

Called if loadstate goes wrong.

8.10.7 Callback: on_post_load(string name, boolean was_savestate)

Called on successful loadstate. was_savestate gives if this was a 
savestate or a movie.

8.10.8 Callback: on_pre_save(string name, boolean is_savestate)

Called just before savestate save occurs (note: movie saves are 
synchronous and won't trigger these callbacks if called from 
Lua).

8.10.9 Callback: on_err_save(string name)

Called if savestate goes wrong.

8.10.10 Callback: on_post_save(string name, boolean is_savestate)

Called on successful savaestate. is_savestate gives if this was a 
savestate or a movie.

8.10.11 Callback: on_quit()

Called when emulator is shutting down.

8.10.12 Callback: on_input(boolean subframe)

Called when emulator is just sending input to bsnes core. 
Warning: This is called even in readonly mode, but the results 
are ignored.

8.10.13 Callback: on_reset()

Called when SNES is reset.

8.10.14 Callback: on_readwrite()

Called when moving into readwrite mode as result of “set-rwmode” 
command (note: moving to rwmode by Lua won't trigger this, as per 
recursive entry protection).

8.10.15 Callback: on_snoop(number port, number controller, number 
  index, number value)

Called each time bsnes asks for input. The value is the final 
value to be sent to bsnes core (readonly mode, autohold and 
autofire have been taken into account). Might be useful when 
translating movies to format suitable for console verification. 
Note: There is no way to modify the value to be sent.

in savestates.

10.20 Member: input

The actual input track, one line per subframe (blank lines are 
skipped).

• If the first byte of each line is '.', ' ', <tab> or '|', then 
  the line is part of same frame as previous, otherwise it starts 
  a new frame.

• First subframe must start a new frame.

Length of movie in frames is number of lines in input file that 
start a new frame.

10.21 Member: rerecords

Contains textual base-10 rerecord count (as one line; emulator 
just writes this, it doesn't read it) + 1.

10.22 Member: rrdata

This member stores set of load IDs. There is one load ID per 
rerecord (plus one corresponding to start of project).

• This member constists of concatenation of records

• Each record is 2-36 bytes long and can represent 1-16,843,009 
  consequtive IDs.

• IDs are interpretted as 256-bit big-endian integers with 
  warparound.

• Initial predicted ID is all zeroes.

Format of each record is:

• 1 byte: Opcode byte. Bits 0-4 are prefix length (prefixlen), 
  bits 5-6 are count length (countlen). Bit 7 is unused.

• 32-prefixlen bytes of ID.

• countlen bytes of big-endian count (count).

Records are processed as follows:

• To form the first ID encoded by record, take the first 
  prefixlen bytes predicted ID and append the read ID value to 
  it. The result is the first ID encoded.

• If countlen is 0, record encodes 1 ID.

• If countlen is 1, record encodes 2+count IDs.

• If countlen is 2, record encodes 258+count IDs.

• If countlen is 3, record encodes 65794+count IDs.

• The new predicted ID is the next ID after last one encoded by 
  the record.

The number of rerecords + 1 is equal to the sum of number of IDs 
encoded by all records.

starttime.subsecond. Only present in savestates.

11 Quick'n'dirty encode guide

1. Start the emulator and load the movie file.

2. Set large AVI option 'set-setting avi-large on'

3. Enable dumping 'dump-avi tmpdump' 

4. Unpause and let it run until you want to end dumping.

5. Close the emulator (closing the window is the easiest way). Or 
  use 'end-avi'.

6. For each tmpdump*.avi file created, on command prompt, do 
  'x264 --crf 10 -o tmpdump_<numbers>.mkv tmpdump_<numbers>.avi'.

7. Do 'sox tmpdump.sox tmpdump.ogg rate -v 32000'

8. Do 'mkvmerge -o tmpdump_video.mkv tmpdump_0000000.mkv + 
  tmpdump_0000001.mkv + tmpdump_0000002.mkv' (list every 
  tmpdump_<numbers>.mkv, with + in between).

9. Do 'mkvmerge -o final.mkv tmpdump_video.mkv tmpdump.ogg'. Now 
  final.mkv contains quick'n'dirty encode.

12 Axis configurations for some gamepad types:

12.1 XBox360 controller:

Axes 2 and 5 (joystick<n>axis2 and joystick<n>axis5) should be 
set to pressure-+.

set-axis joystick0axis2 pressure-+

set-axis joystick0axis5 pressure-+

• This is needed for SDL only. EVDEV sets those types correctly.

12.2 PS3 “sixaxis” controller:

Axes 8-19 should be disabled.

set-axis joystick0axis8 disabled

13 Errata:

13.1 Problems from BSNES core:

• The whole pending save stuff.

• Lack of layer hiding.

• It is slow (especially accuracy).

• Firmwares can't be loaded from ZIP archives.

13.2 Other problems:

• Modifiers don't work with pseudo-keys (SDL, EVDEV).

• Audio for last dumped frame is not itself dumped.

• Audio in UI is pretty bad in quality if game doesn't run at 
  full speed.

• AVI compression levels 10-18 are not compatible with AVISynth 
  AVISource.

• No menus, command based interface (SDL).

• Long commands don't scroll.

• The SDL screen drawing is slow.

• Wxwidgets UI is still pretty buggy.
