In 1995 Sunrise released Akin made by Parallax. This game contains a pixel bug on some MSX machines which is caused by a bug in the compression algorithm used. The routine reads a memory location outside the area it wrote its data to causing the possibility of incorrect data being used later. The memory is filled differently and if the wrong value is read from that particular location, the wrong data is written to the decompressed data as well, causing the seemingly random pixel bug.

About 10 months ago I've investigated the problem more thoroughly and found the problem. Sunrise is already able to release Akin with this fix.

This video shows the difference before and after the fix.
