Specifically the 'NO BG3 FREE' errors some of you get occur when there is no available free VRAM. This will only occur for some of you under some conditions.
Well, since this has been reported already, there no longer is need for me to tell you about it.
That's the exact same error message I got when checking the Killosseum.
I'm going to start a replay later and get a savestate and screenshot for the Zham Fortress bug. I should also try it on another emulator, but my Vista doesn't like bsnes... oh well, time to get SNES9x.
I'm fairly late in the game, so I no longer have access to that one by now, but I plan to replay the game and take note of any bugs I see. If anything else comes up, I'll be sure to make a savestate and take a screenshot for you. I'll get back to you whenever I have something new for you.
That said, you did an awesome job with this, as always.
