Status-wise, I'm in the early testing phase, I've been streaming it on Twitch the past weekend or two.
I discovered that my splash screen code was causing the Equip menu to glitch out, so I decided to drop that idea since it was mostly someone else's code that I didn't fully understand myself. Instead, I decided to make a standard game text box open before the title screen panning, etc. so that I can then share info about the patch.
I've got it displaying properly, but for some reason, the game doesn't always recognize the A button when the the text box is showing, meaning it's not possible to progress the text/close the the box with the A button. Other times, it doesn't recognize other buttons. Sometimes, it doesn't recognize any buttons. WTF? This weirdness seems to change if you reset or reload the ROM, but I can't figure out why this happens. I've checked/watched/set various controller-related registers but with no luck.
Has anyone other FF6 hacker encountered this problem before? Basically, my custom title event script code now looks more like:
$96 (fade in)
$4b,$00,$80 (display Bank 0, Line 0, at bottom of screen)
$b2,$29,$5e,$00 (jump to the pre-existing title screen event script at $ca5e29 as is normal for FF6T)
