- Add support for setBreakpoints request
- Add source locations to stackTrace response
- Source-level stepIn/stepOut/next executions
All of these only work if debug information is available. Otherwise they
work at the instruction level as before.
Before this, the resume save format defaulted to JSON, which could not
be loaded by System40.exe and save/load was sometimes too slow even on
desktop environments.
In xsystem4-android the RSM format has been the default for 9 months and
no problems have been reported. Let's make this the default on all
platforms.
V5 is used until Daiteikoku, and v7 since Rance Quest. Since both are
Ain v6, the save version is determined by the presence of the "MainVM"
field in AliceStart.ini.
Add an option to insert a delay when skipping messages with CTRL.
This is accomplished by overriding the 'A' function. Since the function
to check the state of a key (CTRL in this case) varies by game, an
xsystem4-specific system call is added for this purpose.
Fixes#119
Writing save files in RSM format is only enabled if `--save-format=rsm`
command line flag is specified, because this implementation does not
create save files that are fully compatible with the AliceSoft's
implementation:
* There is no simple way to determine the RSM format version used by the
game.
* There are several unknown fields in the RSM format.
* Empty arrays are represented as NULL pages in xsystem4, so type
information of such objects cannot be saved.
These limitations are not a problem for the following use cases:
* Use the created save files only in xsystem4
* Load save files created by System40.exe
Also, RSM save files are much smaller and faster to read and write than
JSON.
So far only basic debugging functionality is implemented (breakpoints,
stepping, stack traces/variables).
This is not tested against an established DAP client. My intention is to
create a custom GUI frontend and extend the protocol to support
xsystem4-specific features, such as inspecting the scene. (This work is
underway.)
Instruction references are hex-encoded address strings. Clients do not
need to obtain them from DAP requests. This is outside the spec, but it
is needed for a binary-only debugger.
Functions that write directly to stdout (e.g. printf) should generally
not be used any more. Instead, use either sys_message (which respects
sys_silent) or log_message (which will send the message to the debugger
if DAP is enabled). stderr can be used as normal.
The afa implementation from libsys4 now handles basename indexing, so we
use that instead of creating a separate index. Also, afa v1 is now
properly supported in libsys4, so there is no need for the
id_indexed_afa hack.
Some games have assets that are too large to mmap everything on a 32-bit
address space. For example, TT3 has a total of 2.82GB of assets, which
is too large for the 3GB address space limit of 32-bit Linux. On Android
it's even stricter and mmaps of hundreds of MB can fail.
Add a scene_print function which prints a textual representation of the
current scene. This works by attaching a `debug_print` function to each
entity in the scene. This function is implemented for SACT2 and
GUIEngine entities. A default implementation will be used of none is
provided.
This can be accessed from the debugger via the `scene` command (although
the output is typically too much to view in a terminal; it's better to
run `scene_print` somewhere and redirect stdout to a file).
There are now two types of asset management:
1. ID-indexed assets, where IDs are not necessarily sequential
2. name-indexed assets
Name-indexed assets can have additional archives added at run-time. This
is to support the CGManager.LoadArchive function used in Rance Quest
Magnum.
Name-indexed assets always use .afa archives. ID-indexed assets mostly
use .ald archives, except for Daiteikoku and Shaman's Sanctuary.
asset_get_by_name is now case insensitive and ignores the file
extension.
Add an option to control the horizontal scaling of text. This is mainly
to work around text overflow issues in the MangaGamer version of Rance
02 (an appropriate value is set automatically for that game).
Gpx2Plus.CopyStretchReduceAMap behaves differently in the English
version.
Fixes an issue with text being squashed horizontally on the regional
phase menus.
Add a new debugger interface using a simple command language. This is
less powerful than the scheme interface (which still exists) but more
ergonomic for interactive debugging.
This debugger has no external dependencies (it will however use readline
if available) and is included in builds by default.
A sample interaction might look like:
xsystem4 --debug /path/to/game
dbg(cmd)> breakpoint bar
Set breakpoint at function 'bar' (0x00001234)
dbg(cmd)> continue
Hit breakpoint at function 'bar' (0x00001234)
dbg(cmd)> backtrace
#0 0x00001234 in bar
#1 0x00002222 in foo
#2 0x00004444 in main
dbg(cmd)> locals
[0] i: 2
[1] s: "baz"
dbg(cmd)> locals 1
[0] j: 3
[1] obj: { m_i = 0; m_s = "" }
dbg(cmd)> quit
Implement "VolumeValancer" mixer channels from the .ini file. Mixers are
now recursive, with the master and voice channels being parent nodes
(this seems to be hardcoded in system 4, or at least I haven't found
where the hierarchy is specified).
Also implement .wai file support (needed for mixer channel info on sound
files).
This fixes Rance VI which passes SACT2.SP_SaveCG and
SACT2.SP_SetCGFromFile absolute paths like
`system.GetSaveFolderName() + "\\" + "ScreenA.qnt"`.
Also, now savedir_path() uses unix_path() rather than sjis2utf().
Implement a new interface for managing archives. This is mainly to
support loading afa archives alongside ald archives.
Also included here is some code for creating an index for afa CG
archives (the numbers used to reference CGs in afa archives correspond
to the file name, not the position in the archive).
SDL_mixer reads loop information from WAV files if you use the Mix_Music
interface, but NOT the Mix_Chunk interface. So bgm now uses the
Mix_Music interface to get proper looping.
There's also some code here for reading bgi files (taken from xsystem35)
but it's not actually used. There doesn't seem to be a simple way to set
up custom loops with SDL_mixer.
