Ever since I discovered the Touhou Project through this community, I've found myself more and more interested in the world of Doujin games, essentially Japanese indie games. (More info here: https://en.wikipedia.org/wiki/D%C5%8Djin_soft)
I kind of always ignored doujin games in the past as I wasn't a fan of anime and some of the Japanese art styles but I've come around on them and discovered that I was stereotyping these games quite a bit and there were a lot of very high quality games being released that were of interest to me. Being a fan of the Neo Geo game Windjammers, I was quite happy to discover a game known as Crazy Power Disc Perfect, essentially an anime styled remake of Windjammers that throws a lot of new twists into the formula, such as the ability to jump.
After having found the game - no easy feat as it was originally released on the internet in 2006 - I quickly discovered that there was a major problem with attempting to run this game in Windows 8 or Windows 8.1. Within a few seconds of the first match starting, the game would crash. I attempted to debug the issue and found the crash happening in dmsynth.dll, which is included in the DirectMusic API for Windows 8. This same crash appears to be responsible for a lot of other older doujin games crashing too, so I went looking for a fix and found someone had figured this out earlier this year, so I thought I would bring it to the attention of the community.

Hope this helps anyone that has had problems trying to get these games to run under Windows 8.
