A utility that scans all .VGM files in the current directory and |
|
|
|
displays a table showing which audio chips each file uses. |
|
|
|
|
|
|
|
Version 1.1 uses a hybrid detection approach: |
|
|
|
|
|
|
|
- Checks VGM header clock values to detect chip types |
|
|
|
- Scans VGM command stream to detect multiple instances of same chip type |
|
|
|
|
|
|
|
#### Syntax |
|
|
|
|
|
|
|
| `VGMINFO` |
|
|
|
|
|
|
|
#### Usage |
|
|
|
|
|
|
|
No command line arguments are needed. The program will automatically scan |
|
|
|
all .VGM files in the current directory. |
|
|
|
|
|
|
|
The program displays a formatted table with two columns: |
|
|
|
|
|
|
|
- Filename: The name of the VGM file |
|
|
|
- Chips Used: A comma-separated list of audio chips used in that file |
|
|
|
|
|
|
|
The program can detect the following audio chips: |
|
|
|
|
|
|
|
- SN76489 (PSG - Programmable Sound Generator) |
|
|
|
- YM2612 (FM Synthesis chip used in Sega Genesis/Mega Drive) |
|
|
|
- YM2151 (OPM - FM Operator Type-M) |
|
|
|
- YM3812 (OPL2 - FM synthesis chip) |
|
|
|
- YMF262 (OPL3 - Enhanced FM synthesis chip) |
|
|
|
- AY-3-8910 (PSG used in many arcade and home computers) |
|
|
|
|
|
|
|
#### Notes |
|
|
|
|
|
|
|
- The program reads the VGM file headers and scans up to 255 commands from |
|
|
|
the VGM data stream for accurate chip detection. |
|
|
|
|
|
|
|
- Files that don't have a valid VGM header are silently skipped. |
|
|
|
|
|
|
|
- Chip detection uses a hybrid approach: |
|
|
|
* VGM header clock values (offsets 0x0C, 0x2C, 0x30, 0x74) determine |
|
|
|
which chip types are present |
|
|
|
* Command stream scanning detects multiple instances (e.g., "2xSN76489") |
|
|
|
|
|
|
|
- AY-3-8910 clock detection respects VGM version - only checked for v1.51+ |
|
|
|
to avoid false positives from invalid header data in older VGM versions. |
|
|
|
|
|
|
|
#### Etymology |
|
|
|
|
|
|
|
The `VGMINFO` application was written and contributed to RomWBW by |
|
|
|
Joao Miguel Duraes. |
