The ST-0010 is a DSP chip from Seta; it is actually a NEC uPD96050, as confirmed by decapping. It's only used, and barely so, in 1 game:

The development PCB for this chip has the serial SETA ESP-0019C SHVC PCB and the following chips:

ST-0010 Command Summary

Commands are executed on the ST-0010 by writing the command to 0x0020 and setting bit 7 of 0x0021. Bit 7 of 0x0021 will stay set until the Command has completed, at which time output data will be available. See individual commands for input and output parameter addresses.

Command Function Name
0x01 Unknown Command
0x02 Sort Driver Placements
0x03 2D Coordinate Scale
0x04 Unknown Command
0x05 Simulated Driver Coordinate Calculation
0x06 Multiply
0x07 Raster Data Calculation
0x08 2D Coordinate Rotation
