The `--save-folder` command line option, or `save-folder` option in
.xsys4rc, can be used to override the default save folder location.
This is useful in cases where English and Japanese versions of the same
game share a save location, or to isolate saves from a mod, etc.
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).
Joypad support is enabled if UseJoypad = true. This can be overridden by
the --joypad option, which now takes an optional argument, which may be
"off".
The MangaGamer version of Rance 02 has a custom proportional font
implementation which makes assumptions about the font in use. This is
worked around by rewriting their '_CalculateWidth' function to use
fixed-width logic.
I also tried using TTF_SizeUTF8 to get the proper character width but I
found this made the text overflow even worse than using a fixed width
(at least with the default gothic font, perhaps other fonts would fare
better).
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).
xsystem4 can now be run from within a game directory with no arguments.
Alternatively, the game directory can be passed instead of the path to
System40.ini.
This is implemented by inserting special opcodes into the game's code.
When the breakpoint handler is finished, it returns the original opcode
so that execute_instruction can continue executing normally.
E.g.
* start xsystem4 with --debug option to drop into debugger immediately
* run (bp "game_main")
* ^d or \exit to close debugger REPL
* ...drop into a debugger REPL again at the game_main function
global config in $XSYSTEM4_HOME/.xsys4rc (default ~/.xsys4rc)
game-specific config in <game-dir>/.xsys4rc
Supported options so far are "font-mincho" and "font-gothic". Syntax is
the same as System40.ini. E.g.
font-mincho = "/home/user/.fonts/msmincho.ttc"
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.
This is not really a standard ini file, so a custom parser is needed to
access all of the information stored in it (specifically, lists like
"LoadDLL").
This commit also makes flex/bison a hard dependency.
- Create separate directories for source and header files.
- Build code shared between xsystem4 and aindump as a static library.
- Create header dirs gfx/ system4/ and vm/
- Make CG.c/h usable without a running VM
