Jack Bros. freezing after credits

[drakarthus]

So, I beat Jack Bros. and after the credits roll, just before the moment the "THE END" text should appear next to Atlus's logo on the ending screen, the game just freezes and won't actually end properly, yet Red Viper itself seems to still work fine when that happens, as I'm still able to load savestates and change settings just fine (tested on v0.9.6 on an Old 3DS XL).

I also tried reloading a previous savestate and beating the boss again, and the game froze in all 3 of my attempts.

Here are the debug files I've got from the emulator after the game froze, as well as my savestates just before the final bossfight (st7) and at the start of the ending cutscene (st8).
