Hacking 4 DSi XL's With Different Behaviors

[XDel]

I have 4 DSi XL's, one which was my original that I hacked a long while ago, and three which I recently purchased and hacked using the method that I found here:

https://dsi.cfw.guide/

The thing is that the old one has issued with Lego games in that the movies in game glitch a lot, where as on the three newer consoles it does not.
Also on the old DSi XL, I can not load one of my Korg Virtual Analog Synths, but can on the other three... (EDIT) ...it tells me,"The DSi binaries are missing. Please get a clean udump of this ROM, or start in DS mode". Though the other three systems never say a word about it and just load it.

Lastly one of the three newer DSi XL's has a strange thing where once in a while the sound begins to screech. What might cause that?

Thankx for any help in advance!

For the LEGO games, it may be that your settings are inconsistent.
I only have one LEGO game (LEGO® Indiana Jones™ 2 The Adventure Continues), but these settings worked for me as far as I've tried:

Run in: DS Mode
ARM9 CPU Speed: 67mhz (NTR)
VRAM Boost: On
Heap Shrink: Off
Bootstrap: Release

Like I said though, this is only my settings and not necessarily the best settings

Thank you, where do I find Heap Shrink?
