"update ngcd sprite block" is 1 of the very old functions added in the glory days when I tried to help for a certain translation of ssrpg... ! It's useless today, but you never know, it could be used some day, even if it's highly unlikely.
0.96.10 just released, you have another toy to break !
Yeah yeah... the thing about the hotfix version is that it fixes only the emergency. Here the emergency was that I succeeded to break all the top of the raine's main menu !
The one with sf2mix and all the fixes contained in this thread will be released today, I hesitate to do it now because I am still currently a little sleepy so it's not a very good idea to do anything like that in such a state... ! But promised, it will be released within at max 8 hours and very probably earlier.
