이안은 뭐하니?

System Requirements

• System: Apple II family equipped with a 65C02 CPU (Apple IIe, IIc, or higher)
• RAM: 128KB

Controls

• Movement: Cursor keys (Left, Right, Down)
• Rotation: A key

Key Notes

• Most of the graphics were adapted from the Game Boy / Game Gear versions of Puyo Puyo.
• There is some background noise (pop noise) during music playback.
• The overall polish of the game, including difficulty settings, is still lacking.
• The display looks much cleaner when using the Composite Idealized mode in AppleWin video settings.

Personal Reflections from the Developer...

• Unless the noise issue is resolved, it's best to avoid using SoftDAC. For sound, sticking with Mockingboard is the way to go...
• I implemented a double frame buffer (Page 1 & 2), but it feels like an unnecessary luxury for Double High-Resolution (DHGR) graphics.
• It's hard to write structured and organized code in Assembly... The code just kept getting messier as the project went on 😭

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
