I have written a lot of code pieces over 10 years. Many of them are not very sophisticated, but I hope my product will help someone.

Most of tools are hosted at GitHub. Some abandoned codes can be found at Google Code.

My Tools

See GitHub page for full list of my tools.

Susie Plugins

Susie is an old-school picture viewer for Windows, which can load additional formats by adding Susie plugins (*.spi). In Japan, Susie plugin is often used for decoding custom image formats inside a game.


I have some reverse-engineering skills. So I created some unofficial patches that make the original softwares more useful.

ふみぃ's MIDI tools (Cherry, TMIDI)

The following patches are for ふみぃ's Japanese MIDI sequencer/player tools. Though they are old good tools, they have only Japanese UI.
