Rdos AdLib Catcher is a TSR (terminate and stay resident) program which features the very first method of capturing OPL data from a running game. It uses 386 protected mode to intercept writes to the AdLib I/O port and save the data to a file in RAW (Rdos) format.
As it ran on real hardware, it suffered from a number of drawbacks:
- Games could not use protected mode, meaning many could not have their music captured at all (e.g. Zone 66 (DOS)).
- Games would run very slowly due to the software overhead of the capture process.
- Capture files were limited to fairly small sizes, so some games could not have full songs captured, especially if they wrote a lot of redundant data to the OPL chip (e.g. Stunts (DOS)).
The program accepts two optional parameters:
RAC.EXE [c] [s]
- c - clear music buffer
- s - save music buffer into file RACDATA.RAW in current directory
