\end_layout

\begin_layout Standard
Raw binary dump of host memory.
 Only present in savestates.
\end_layout

\begin_layout Subsection
Member: savestate
\end_layout

\begin_layout Standard

 Only present in savestates.
\end_layout

\begin_layout Subsection
Member: input
\end_layout

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

\begin_layout Itemize
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.
\end_layout

\begin_layout Itemize
First subframe must start a new frame.
\end_layout

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

\begin_layout Subsection
Member: rerecords
\end_layout

\begin_layout Standard
Contains textual base-10 rerecord count (emulator just writes this, it doesn't
 read it) + 1.
\end_layout

\begin_layout Subsection
Member: rrdata
\end_layout

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

\begin_layout Itemize
This member constists of concatenation of records
\end_layout

\begin_layout Itemize
Each record is 2-36 bytes long and can represent 1-16,843,009 consequtive
 IDs.
\end_layout

\begin_layout Itemize
IDs are interpretted as 256-bit big-endian integers with warparound.
\end_layout

\begin_layout Itemize
Initial predicted ID is all zeroes.
\end_layout

\begin_layout Standard
Format of each record is:
\end_layout

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

\begin_layout Itemize
32-prefixlen bytes of ID.
\end_layout

\begin_layout Itemize
countlen bytes of big-endian count (count).
\end_layout

\begin_layout Standard
Records are processed as follows:
\end_layout

\begin_layout Itemize
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.
\end_layout

\begin_layout Itemize
If countlen is 0, record encodes 1 ID.
\end_layout

\begin_layout Itemize
If countlen is 1, record encodes 2+count IDs.
\end_layout

\begin_layout Itemize
If countlen is 2, record encodes 258+count IDs.
\end_layout

\begin_layout Itemize
If countlen is 3, record encodes 65794+count IDs.
\end_layout

\begin_layout Itemize
The new predicted ID is the next ID after last one encoded by the record.
\end_layout

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