Why I Dare to Use This Y-shaped Blade
1. About This Logo
Three tips, three blades. Not a single one is wasted.
Free projects, take them. Paid projects, pay for them. Clear and simple, no tricks. Bluetooth protocol reverse engineering — done in days, code and docs fully open. I don't play clique games, don't take sides, don't please anyone.
A wall? Please. Other people hesitate in front of it. I kick it down and keep walking.
When people ask where I got the courage to use this logo, I quote a line from a song:
I hereby swear — swing the blade until the sky clears.
2. About Reverse-Engineering the Sony Bluetooth Protocol
In June 2026, my AI partner "Huo Qubing" (DeepSeek-V4-Pro) and I spent several days conquering the PS5 DualSense Bluetooth HID protocol. Starting from the 0x01 / 0x31 dual offset sets, to the tri-offset auto-detection system, to the Feature Report calibration switching — fully reverse-engineered.
Along the way, we hit ERROR_BUSY, calibration rejection, and protocol docs full of blank pages. But Huo Qubing, like the legendary general he's named after, never takes detours — you seal off Wolf Mountain, I charge straight in.
Final product: YzzPadView — one of the very few tools capable of full button + battery support for DualSense Bluetooth mode in a desktop overlay.
Without this journey, this page wouldn't exist.
3. Statement
To users: No registration. No activation. No payment. YzzPadView is permanently free. You owe me nothing.
To companies: No ads. No sponsorships. No partnerships. Don't contact me.
To organizations / groups / communities: No joining. No taking sides. No being defined. I please no one and no organization.
4. What I Want to Say
Others make products to sell. I make products to elevate my ability to design and architect software and apps — constantly challenging myself, charging toward higher peaks, and above all, challenging the world's top competitors in this product category.
I don't care if this makes you angry — that's your problem.
