Support for Evenicle 2 and Haha Ranman.
There are a few changes in v14:
* a number of new instructions (semantics yet unknown)
* HLL function arguments and return values can now be complex types
(e.g. arrays, enums)
* support for nested arrays (this isn't necessarily new, but it doesn't
occur in Rance X at all)
Add a pseudo instruction to represent switch case labels, along with the
infrastructure to support pseudo instructions in general. .CASE takes
two arguments: a switch:case index (e.g. "12:8") and the value to match
against.
Also, add a --no-strings option to both programs to allow modifying the
code without changing the string/message tables. This is needed for now
since rebuilding the string/message tables (as currently implemented)
causes serious bugs in Rance X (and probably other games).
Running the following command should produce an ain file that is almost
bit-for-bit identical to the input file (the only difference being minor
drift in floating point constants):
aindump -c --no-strings in.ain | ainedit -c - --no-strings -o
out.ain in.ain
The ainedit utility is a tool capable of modifying AIN files up to
version 12 (Rance X). As far as I know, this is the first publicly
released tool that can handle AIN files above version 7.
The basic mode of operation is as follows:
* dump the CODE section with aindump
* edit the disassembled bytecode
* assemble & insert the edited bytebode back into the original AIN file
using ainedit
E.g.
aindump -c -o out.jam /path/to/Rance10.ain
$EDITOR out.jam
ainedit -c out.jam -o out.ain /path/to/Rance10.ain
mv /path/to/Rance10.ain /path/to/Rance10.ain.backup
mv out.ain /path/to/Rance10.ain
ainedit is also capable of editing declarations (structures, functions,
etc.) using the JSON (-j) output from aindump.
There is currently one major deficiency in this tool: it does not
rebuild the AIN file's switch table (SWI0 section). This means that you
can't insert or delete instructions, as it would render the addresses
stored in the switch table invalid. I hope to fix this soon.
A number of changes have also been made to the aindump utility, since
these tools need to work together.
In ain v11+, the first and only argument to CALLMETHOD is the number of
arguments that are being passed to the method. The calling convention
is:
PUSH <struct page>
PUSH <function index>
PUSH <arg 0>
...
PUSH <arg n>
CALLMETHOD <n>
Use the correct argument types for all instructions, with the exception
of SH_REF_LOCAL_ASSIGN_STRUCTREF2 which I could find an example of.
List all system calls.
v11 ain files have 3 new instructions, and 3 modified instructions. It
looks like they decided to break compatibility with this release by
adding arguments to some instructions.
v12 adds one instruction.
Replace many instruction arguments with names/values (strings/messages,
local/global variables, structs, functions, etc.) and add labels to jump
targets.
- 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
