My SD card is new, I also tried more than 1 of them. btw, the different hooks on Gecko OS make no difference for the game unless the user has USB Gecko (I don't). These issues are unique to Gecko OS and ANY of it's alternative loaders, they don't happen in Riivolution, and that is on the same cards that I used without any different data.
I believe the strange announcer calls are either an issue with how Gecko OS works, or the RSBE (Replacement Soundbank Engine) code, and said code needs fixing/another update, when I remove the sfx file for announcer calls, the announcer calls are normal again (which also means no modified announcer calls, and I can't work with that >.>). Also, the size appears to be the same between the sfx file, and an extracted sawnd file.
I still don't know why 'Waluigi over Diddy (Final)' causes the music to glitch/change in-battle, but it also doesn't happen in Riivolution, all I know is that his moveset files (only of the '(Final)' version) have something to do with it, but I don't know why it happens in Gecko OS, but not Riivolution, and unfortunately, any older version of Waluigi over Diddy does not work with his SFX pack, and well... I really don't want a mute Waluigi, because that kinda' wrecks the personality of him in the game.
That's about all I know about it. I can't switch back to Riivolution because the cBliss expansion causes random freezes on stage select if ran on Riivolution. You can ask me more questions though about anything that might be related to these issues I'm having. Thanks for any more suggestions as to how to fix these issues. If it's easier to just fix the random-freeze-on-stage-select issue with cBliss on Riivolution, then any idea how that could be done?
Edit: Nevermind, I fixed the cBliss freezing for Riivolution.
