Rhythm Heaven Megamix won't load, boots to black screen

[ghost]

System model:

New 2DS XL SysNAND version (+emu/redNAND version if applicable): 11.14.0-46J Sys, no EMU Entrypoint (How/what you're using to boot Luma3DS): The Luma updater says I have a SIGHAX payload (I have boot9strap, though) I hacked from seedminer comboed into UNSAFE_MODE

Luma3DS version: luma3ds v10.2.1-d0a44fd2 (I think it's this https://github.com/Nanquitas/Luma3DS) Luma3DS configuration/options:

Screen brightness: (4 )

Splash: (N/A )

Splash duration: ( N/A)

PIN lock: (N/A )

New 3DS CPU: (Normal/off) Enable loading external FIRMs and modules: (Yes )

Enable game patching: (Yes)

Show NAND or user string in System Settings: (Yes )

Show GBA boot screen in patched AGB_FIRM: (Yes)

Set developer UNITINFO: (No)

Disable Arm11 exception handlers: (No)

Enable Rosalina on SAFE_FIRM: (No)

Explanation of the issue: I'm using a Japanese Sysnand on an American sold system. Whenever I try to boot Rhythm Heaven Megamix (the US version), after I get to the 3ds before-game splash thing, I get a black screen. The JP version works, but I can't read all of the game, and would like to play in English if possible. Even by using Luma Locale Changer to change the game to US, I still get a black screen. I can boot to Rosalina but not the Home Menu.

Steps to reproduce:

1. Use JP sysnand, install cia of Rhythm Heaven Megamix

2. Get black screen, after the 3ds screen

No error dump. Sorry.
