Sega Ages 2500 Series Vol. 5: Golden Axe

Just looking at game recources this weekend

The main data is located in "stash" dir as .bin files Bin files are simple containers with multiple files inside Main file types includes .snm, .sno, .svr

Using this plugin blender loads .sno files successfully but i really can't tell if it was loaded correctly I'm expecting to see game models but it looks like skeletons?

Script for unpacking .bin files

#!/usr/bin/env python3

from dataclasses import dataclass
from struct import iter_unpack, unpack
from sys import argv
from os import makedirs, path

HEADER_SIZE = 0x50
HEADER_FORMAT = '<68sIIxxxx'

@dataclass
class FileHeader:
    name: str
    size: int
    offset: int

def read_data_offset(file):
    file_offset = file.tell()
    file.seek(0x48)
    offset, = unpack('<I', file.read(0x4))
    file.seek(file_offset)
    return offset

def unpack_bin(binpath):
    with open(binpath, 'rb') as bin:
        data_offset = read_data_offset(bin)
        header_count = int(data_offset / HEADER_SIZE)

        headers = []
        for i in range(header_count):
            name, size, offset = unpack(HEADER_FORMAT, bin.read(HEADER_SIZE))
            headers.append(FileHeader(
                name.decode('shift_jis').rstrip('\0'),
                size,
                offset
            ))

        _, binname = path.split(binpath)
        base = path.join('out', binname)
        makedirs(base, exist_ok=True)
        for header in headers:
            entrypath, entryname = path.split(header.name)
            outdir = path.join(base, entrypath)
            outfile = path.join(outdir, entryname)

            makedirs(outdir, exist_ok=True)
            with open(outfile, 'wb') as ofile:
                print(f'Unpacking {header.name}')
                bin.seek(header.offset)
                ofile.write(bin.read(header.size))

if __name__ == '__main__':
    for binpath in argv[1:]:
        unpack_bin(binpath)
