Ugh. You reminded me of a game I can't play... because for whatever reason the terrain doesn't load for me. So I'm running around on the void, as it were. :p
But if Golden Sun - Dark Dawn could have its sound issues on the emulator repaired, then I'm sure Lunar Knights can have its issues fixed on the emulator too.
I did better on the Aeonian Night Windows 7 PC (got to the second boss in 2016) though. Now? Not even near a first boss, haha.
LK was fun, but then, it's probably the cat's doing. :3
That reminds of when I was a kid, it was possible for me to occasionally fall into the multicoloured void in Spongebob Squarepants: The Movie Game. That said, I've got all the Golden Sun games on my silver R4 so I may get to those in the future.
I have Lunar Knights on my original R4 cartridge and I didn't even have to patch it. Haven't played it yet.
Games Progress:
I've completed every level in Looney Tunes: Cartoon Conductor except Can Can (remix). Can Can and it's remix versions have a lot going on, so losing track of the notes means that you'll lose quickly. Some of the remixes are actually easier than their original versions (one of them, I got A rank. I told myself that I'd laugh if I got perfect rank and while I didn't, it was close enough that it got a laugh out of me anyway).
