AK1025
A firmware that works on an ATJ2091N player worked on a player with had a strange AK1025 chip. The AK1025 seems to be a clone of the ATJ2091.
The i2c port seems to be different from the one on tha ATJ2085. Unmodified s1debug doesn't work anymore on these devices. s1giveio, with modified usb pid, and vid settings seems to work
lsusb response for an ak1025 chip:
Bus 001 Device 003: ID 10d6:ff66 Actions Semiconductor Co., Ltd
