To dump/inject AIL engine Script from v1 to v3
v3: ????-2001
v2: 2002-2005
v1: 2006-????
Initially, I didn't expect there would be so many types of AIL engine scripts, so I started by creating tools for each script type as I encountered them, resulting in AILScriptSimpleToolV1-V3. I then integrated them into AILScriptSimpleToolPlus through simple copy and paste. However, since I didn't have the energy to carefully analyze many OPs in V1 and V2 scripts, and the original code was written too casually to modify easily, I only added options for overwriting the original text and freely setting the overwrite starting position. This helped avoid offset overflow issues caused by u16's small maximum value and garbled text problems caused by overwriting unanalyzed sentences. While fixing some details as much as possible, this became AILScriptSimpleTool++.
AILScriptSimpleTool# completely reconstructed the extraction and reinsertion of V1 and V2 scripts (V3 remains unchanged). I still didn't analyze their OPs, but the new tool detects which sentences in the text block weren't extracted and automatically guesses where their offsets are stored. Naturally, some sentences might be guessed incorrectly, but you can manually delete them or find the actual location storing their offsets to fix them, as the reconstructed new function only makes modifications at locations based on the offset addresses (hexadecimal numbers before ":::::") stored in the txt file.

To decompress/compress Lilim engine .scr files to achieve No-packet-read
To (decrypt and decompress/compress and encrypt) AZ system engine script files
For script files in normal AZsys resource archive, you need key to decrypt/encrypt them
And there are 4 known keys in GARbro :
"Clover Heart's": 3786541434
"Triptych": 501685433
"Amaenbou": 2938115999
"Reminiscence Blue": 2849404158
You can also use guess_key func in this programme :
Use crass to unpack script.arc and make that output_dir as input_dir, the programme will use the smallest file to guess key.
If the guessed key is wrong, delete the smallest file the programme shows and try again(A file size of 1.5-3.0kb is preferred)
For script files in AZsys encrypted resource archive(need to use special parameter『system="path/to/system.arc"』 when using crass to unpack)
you needn't key, but pure file content without signature if you want to encrypt the files back
Use crass with special parameter to make it or use fixed GAR in Ellefin directory in this repository to get original encrypted files and then use the tool to make it

To decompress/compress GPK2 .scb files
Fix offsets in .sf0 as well if possible
After reinject .scb and .sf0 files, you need to use SysdatTool to dump system.dat as .json and reinject it referring new .scb/.sf0 files, or game jumps will be wrong
(Another role is to make the lastWriteTime of system.dat later than any .scb/.sf0 file because the stupid engine will DELETE files created later than system.dat)

If the game has no key(can be correctly extracted by the default method in GARbro), keep key empty
Or you can use known keys in GARbro
You can also manually find the key in game.exe, here exists the method to find key
