# SPCtag : Java SPC tag reader (SNES Sound Files)
[SPCTag](https://github.com/ullenius/spctag) is a Java stand-alone command line app for reading the ID666 tags from SNES SPC-files.
SPC-files are sound files containing ripped chiptune music from Super Nintendo and Super Famicom games. They are named after the Sony SPC-700 sound chip created by Ken Kutaragi (who later became the father of the Playstation).
**Not** for *PKCS#7* certificates who share the same filename extension.
## :desktop_computer: Usage
```sh
usage: spctag
-j,--json output JSON
-v,--verbose verbose output
-V,--version print version
-x,--xid6 print xid6 tags
```
For example:
```sh
$ java -jar spctag -v --json "/warez/spc/dkc2/17 Stickerbrush Symphony.spc"
```
```json
[

## Features
* :heavy_check_mark: 100% Java (Java 17) :coffee:
* :heavy_check_mark: Supports UTF-8 encoding in the tags!
* :heavy_check_mark: Command line. Multi-platform.
* :heavy_check_mark: Batch processing using wildcards is possible! For example: `java -jar spctag *.spc`
* :heavy_check_mark: xid6 support (extended tags).
* :x: Edit tags (as of yet)
## :floppy_disk: Building
This is a Maven-project.
### Linux / POSIX
Run:
```sh
./build.sh
```
### Windows
Run:
```dosbatch
mvnw.cmd clean install assembly:single
```
to build the JAR-file.
## :file_folder: Binaries
Binaries are included with every release on Github to simplify for end-users who
can't compile stuff on their platform.
## Character encodings
Supported character encodings are:
* ASCII
* UTF-8
* latin-1
The program auto-detect character encodings, if text is not valid UTF-8 then
latin-1 is used. This may result in mojibake.
Noncharacters in UTF-8 are disallowed for security reasons.
* [Which code points are noncharacters?](https://www.unicode.org/faq/private_use.html#noncharacters)
## :wrench: Development
1. I wrote this because there was a lack of tools supporting the SPC-format.
2. And it would be a fun project to learn binary I/O in Java.
3. Lastly, **spctag** has the best support for parsing the *"Emulator used for dumping SPC"*-tag :grin:
Most of the existing tools are 15-20 year old legacy Windows programs that won't run on modern computers. The source code is lost. Or it was written in C/C++ for 32-bit architecture and won't compile on modern 64-bit computers.
Java is multi-platform and you can run and compile 20-year-old Java programs without any issues. So I'd figure this would be a suitable platform for posterity.
Hopefully doing it in Java makes it easy to convert to XML and JSON, as well as persisting it in databases using SQL.
## :id: Emulator Dump Tag
The *Emulator used for dumping*-value is set by 1 byte-flag. In two different
offset locations depending on if the SPC-file is using binary or text-format for
storing the ID666-tag.
* Binary offset `0xD1`
* Text offset: `0xD2`
There are two different set of specifications for emulator codes available. The legacy SPC-file specification and the newer Japanese one. SPCTag supports both of them.
### :jp: Japanese spec
The following byte-values are used according to the [Japanese spec](https://dgrfactory.jp/spcplay/id666.html):
| Emulator name | Text format | Binary format |
|---------------|-------------|---------------|
| Unknown | 0x30 | 0x00 |
| ZSNES | 0x31 | 0x01 |
| Snes9x | 0x32 | 0x02 |
| ZST2SPC | 0x33 | 0x03 |
| Other | 0x34 | 0x04 |
| SNEShout | 0x35 | 0x05 |
| ZSNES / W | 0x36 | 0x06 |
| Snes9xpp | 0x37 | 0x07 |
| SNESGT | 0x38 | 0x08 |
Note: *Other* and *Unknown* are both specified with unique values (?) somehow...
### :older_woman: Legacy spec
Only 3 values are defined in the legacy spec (SPC File Format v.0.31 txt-file)
| Emulator name | Text format | Binary format |
|---------------|-------------|---------------|
| Unknown | 0x00 | 0x00 |
| ZSNES | 0x01 | 0x01 |
| Snes9x | 0x02 | 0x02 |
### :factory: Factory Method
* *se.anosh.spctag.emulator.factory* contains a factory method.
* Used for creating immutable *Emulator*-objects based on the two aforementioned tables.
#### Usage example:
```java
Emulator emulatorUsed = EmulatorFactory.createEmulator(0x31, Type.JAPANESE) // Type.LEGACY is also available
```
