FlowerScript

An assembler / disassembler tool for InnocentGrey 's script format

Currently it can (dis)asm all scripts from

• FLOWERS Le volume sur ete.
• FLOWERS Le volume sur hiver.

Use iglib as a package

Usage

# Disasm

from iglib import flowerscript, igarchive

with open('script.s', 'rb') as fp:
    # gbk for chinese translated games
    result = flowerscript.disasm(fp, encoding='cp932')
with open('script.py', 'w') as fp:
    for line in result:
        print(line, file=fp)

# Assemble

s = flowerscript.Assembler(encoding='cp932')

# Example result: start.s from FLOWERS Le volume sur ete
# Many operations are documented in 'iglib/flowerscript.py'
