Script Extraction Help - Ashita no Kimi to Autame Ni

[Ojamajo_LimePie]

I'd like to translate Purple Software's Ashita no Kimi to Autame Ni. Unfortunately, I can't figure out how to extract the script. I can use ExtractData to unpack the CPZ files, but they turn into PS2 files, which I can't find a way to open. Is there a way to turn these into TXT files or something similar? I'd just like something I can easily translate line-by-line, minus messing around with any encoding (which I'll worry about once I actually finish the initial scripts.)

Can you post some of the smaller/obviously script files? And the main executable, if it's not too big.

Can do! I've made a ZIP containing three sample files, and attached it to this post. The EXE was just a tiny bit too big to attach, so I uploaded it here. Hopefully, I did everything correctly.

Thanks for your help.

Okay, I'll have a look...

解析しちゃう悪い子はお仕置きなんだよ、メッ！♪…誰に言ってるの？

Header size is 48 bytes.
[0x24] is compressed size
[0x28] is uncompressed size
[0x2C] zero?

Decompression algorithm should be the same as usual, untested:

	goto 3;
}

Here's a working decryptor/unpacker/dumper. Don't know when/if I can get time to dig through bytecode interptreter, but this should at least allow you to start on the translation.

Thanks for all your hard work!
