## Usage
|
||||
|
||||
`./hootvopm.py -t chip_type input_file`
|
||||
`./hootvopm.py [-b] -t chip_type input_file`
|
||||
|
||||
Input file can also be `-` to read from stdin.
|
||||
|
||||
Output is dumped straight to stdout; redirect it to a file if you want to save it.
|
||||
|
||||
Pass -b to instead read straight binary data instead of comma-separated values.
|
||||
|
||||
### Currently-supported chip types
|
||||
|
||||
* OPM
|
||||
* OPN
|
||||
* OPNA (equivalent to OPN)
|
||||
* Raw data in 32-byte groups (see below)
|
||||
|
||||
#### Raw data format
|
||||
| Offset | Value |
|
||||
|--------|-------------|
|
||||
| 0x00 | DT/MUL* |
|
||||
| 0x04 | TL* |
|
||||
| 0x08 | KS/AR* |
|
||||
| 0x0C | AMS-EN/D1R* |
|
||||
| 0x10 | DT2/D2R* |
|
||||
| 0x14 | D1L/RR* |
|
||||
| 0x18 | FL/CON |
|
||||
| 0x19 | AMS/PMS |
|
||||
|
||||
Rows marked with * are groups of 4 bytes, one per operator.
