IMS Player

Hi,

 

I’ve been working on an IMS music player for the Apple II.
(It required the SD Music DX OPL3 card)

IMS file:
For those interested in the technical specs of the 1990s Korean Chiptune/MIDI format (.IMS) powered by Yamaha OPL chips, here is the detailed English wiki page.

Playing IMS songs on Apple II

There is still a lot left to tune.

The next big challenge is Hidden Reading.

A 20KB buffer is not enough for longer songs, so the player must read more IMS data from disk while the music is playing. I have already done similar work in my MIDI and VGM players, so I plan to bring that experience into this IMS player as well.

 

I’m also planning a few UI features:

A level meter, so the screen feels alive while music is playing.

A progress display, so users can roughly see where they are in the song.

There are still many details to solve, but the player is finally starting to take shape.

 

Thanks

Ian Kim
