Array rank can't be inferred from JSON data since arrays and structs are
indistinguishable. So we get it from the ain file instead.
Sengoku Rance is mostly playable as of this commit.
If Chibi-Scheme is installed, enable a debugger which can be used to
inspect the state of the VM when an error occurs.
So far only supports printing local/global variables. E.g.
dbg> (print-variable "g_theSactMenu")
...
dbg> (print-locals)
...
The "SaveFolder" key in System40.ini gives the name of the save
directory. Earlier versions of system 4 treated this as a relative path
in the game directory, while later versions treated it as a path
relative to "$USER\My Documents\AliceSoft\$GAME_NAME". I've chosen the
latter approach, but using a xsystem4-specific directory to avoid
reading/overwriting saves created by System40.exe.
system.GlobalSave
system.GlobalLoad
system.GroupSave
system.GroupLoad
Save files are uncompressed JSON objects for now. Compatibility with
System40.exe saves would be nice, but the format appears to be
encrypted.
Minifying & compressing the JSON should be done at some point but for
debugging purposes I've left it totally uncompressed.
This commit also fixes a bunch of undefined behavior when assigning to
'heap[...]' with an rvalue that could initiate a realloc of the heap.
Also implement a feature to track leaked heap memory (DEBUG_HEAP).
With this, it is now possible to hold CTRL through the entire Rance II
digest version without crashing.
Implement all of the simple copy functions, with the exception of
DrawGraph.CopyColorReverse, which is undocumented and appears to be dead
code (at least in the version of SACT2 that shipped with the SDK).
...and add OutputLog.dll stubs.
The calling convention no longer has HLL functions reaching into the
stack. The previous implementation didn't even work since the return
value could overwrite an argument that needed to be freed.
HLL libraries are compiled into the executable rather than dynamically
loaded as in early versions of System 4. These days AliceSoft does the
same thing.
