The reason I needed 181 to work is because I spent literally weeks setting up a HyperSpin with databases and genres based around the 181 database.
Finally got it all working, then spent another week updating my ROMset to 181. Then after finally testing everything I noticed one of my favorite features was missing. You've saved me a ton of time. I haven't a clue on where to look in the way of documentation for when features get changed around... but now that I have my full 181 set and everything working properly I don't think I'll be updating for a long time.
