WIP This feature is work-in-progress (waiting for next SDCC update)
This Build tool option allow to add an application related information to binary data (right after the application ). It is inspired by the metadata that Konami used for its Game Master cheat cartridges.
:: Application extra data (comma-separated bytes starting with data size) set AppExtra=3,5,0x00,0xC1
Here is the format to use: DataSize, DataType, Data1[, Data2, ...], DataType, Data1[, Data2, ...]. Where:
- DataSize: The size in byte of the extra data excluding this byte
- DataType:
| Code | Data type | Data content |
|---|---|---|
| 0x0X | Reserved | -- |
| 0x10 | Application name | Zero-terminated string |
| 0x20 | Number of life/continue address | 2 bytes (RAM address) |
| 0x21 | Life-point address | 2 bytes (RAM address) |
| 0xFX | Reserved | -- |
