Thanks a lot. 🤗

can you help me with something?

I know how to find Oodle games,
Oodle games have dll file inside the game and Oodle scan tells us which method that game used,
Kraken, Mermaid, Selkie. Jc4 used K&M ACO use Mermaid only. Please Correct me if I'm wrong 🤗

also i need to know, On none Oodle games
How can i find what kind of Compression,
used for the game?

It's very important to me to make best compression method for every game 🎮
