update old tags.
Modified cdrom.c to expose metadata read/write functions, and changed
chdman to use them. Also changed chdman to parse old-style metadata and
convert it to new-style metadata since we're going to need to re-do this
anyway and the two won't hash to the same value.
Added completely untested support for the ident metadata to the hard
disk creation path. If a filename is provided immediately after the
source filename, it is taken as an ident file and processed for CHS
data and added. Other metadata types can be added afterwards via
-addmeta.
Updated CHD format to version 4. Checksums are now computed and
stored separately for raw data and metadata, and metadata is now
checksummed by default.
We will need to go through all existing CHDs, run a chdman -update
on them, and update the SHA1s stored in the drivers to accommodate
this (MD5s should be removed).
Updated chdman to support a generic metadata addition system:
chdman -addmeta <chdfile> <tag> [<index>] <sourcefile>
The <sourcefile> is examined and if it appears to be strictly text,
any EOFs and trailing EOLs are stripped, and the result is NULL-
terminated to match the behavior of existing metadata.
Updated chdman to report and fix errors in the raw and metadata
SHA1s.
Changed the CHD verify interfaces to pass back a structure containing
all the necessary data for verification and fixing.
metadata with pre-decoded frame information. Modified chdman to
automatically produce this for CHDs that are of the appropriate
parameters. To fix up existing CHDs, use chdman -fixavdata on the
CHD.
Modified the laserdisc core to leverage the pre-decoded frame
metadata, which is now required. This improves seek times when
searching and allows the player-specific emulation access to the
VBI data as soon as it would really be available. Changed update
callback timing to fire just before the first line of VBI data
would be read; at that point, the frame selection is assumed to
be committed.
Converted PR-8210 emulation over to using the actual MCU from the
laserdisc player. This MCU controls low-level functions such as
slider position and laser on/off, and receives decoded vertical
blanking data in order to make decisions. Removed old HLE behavior.
Note that the overlay text is displayed via the UI; this is
temporary and will be fixed shortly.
Converted Simutrek-hacked laserdisc emulation to using the actual
MCU from the game, which in turn hands off commands to the PR-8210
MCU. This is still not 100% but is pretty close at this point and
achieves the correct behaviors in most cases.
Fixed Cube Quest overlay scaling to cover the whole screen.
Changed laserdisc video parameters to position the screen area at
the bottom rather than the top, since this corresponds more closely
to standard line numbering.
Extended the vbiparse code to support pack/unpack, and to more
fully document all the meanings of the VBI codes.
Updated ldplayer to support slow/fast forward movement, frame/chapter
display, and separate controls for scanning/stepping.
Added new built-in variable "frame" to the debugger.
Fixed device-based ROM loading to support loading ROMs from the
game's ZIP as well.
streams and a delta-RLE pre-encoding. Added optimized
case for the Y/Cb/Y/Cr video encoding case. Cleaned up
the code.
Updated avcomp.c to use the new huffman.c functions.
Reworked configuration options to allow for both input
and output of naturally aligned data streams. Updated
chdman and laserdsc to use the new interfaces. New
compression gives an additional 3-7% over previous
attempt and compresses the dummy CHDs down significantly.
tool which walks through either an AVI or CHD capture from a
laserdisc and ensures that there are no anomalies lurking in
the VBI data.
Added new option to chdman, where if you use -createav with
a special filename (either 2:2 or 3:2) it will create a fake
laserdisc files with the equivalent cadence. This can be used
for testing until full captures are available. Most games used
2:2 apart from Dragon's Lair and Space Ace, which were 3:2.
Note that even though these files are essentially blank, they
are Huffman-compressed, meaning that the maximum compression
ratio you will get is 8:1, so they still end up ~5GB.
Moved error strings from chdman.c to chd.c, where they can be
fetched from any caller via the new chd_error_string()
function.
Updated vbiparse to improve Manchester code decoding. It now
assigns a confidence level per bit based on how solid the
data is. Also added a new function vbi_parse_all which parses
the white flag and all three lines of metadata from a
laserdisc frame. It then compares line 17 and 18 against each
other and selects the most likely candidate based on per-bit
confidence and other factors.
Added frame number display to laserdsc.c. It is off by
default, though most players can be configured to turn it on
(not sure if any actually do). It can be manually toggled via
the backslash key during playback.
now simply requires an AVI file input.
Relaxed VBI Manchester code clocking to allow for a little bit
of wiggle when finding the clock.
Changed laserdisc support to parse white flags and other data
from the VBI data directly, rather than relying on the textual
metadata. Expanded video frame cache to 3. Changed the way
frames are assembled to decrease the likelihood of getting an
interlaced weave. Fixed sound creation so that it is done at
reset time instead of device start, when the sound devices aren't
yet live.
Fixed bug in winwork that caused the creation of single work
items to return NULL, and thus lead to massive memory leaks when
using A/V CHDs.
suffixed with _func. Did this throughout the core and
drivers I was familiar with.
Fixed gcc compiler error with recent render.c changes.
gcc does not like explicit (int) casts on float or
double functions. This is fracking annoying and stupid,
but there you have it.
Subject: [patch] Fix some comments
Hi mamedev,
The following patch updates the initialization comments at the top of
