Homebrew Launcher crashes on Old 3DS

[ChainSwordCS]

On Old 3DS only, when you start ChirunoMod and then try to open the Homebrew Launcher (via CIA), the 3DS will crash with an Arm11 exception like this:

This issue probably affects all releases of ChirunoMod. It is confirmed to affect both the latest stable release (v0.2.2) and the latest v0.3-nightly build.

It appears that this is not a regression from HzMod. All versions of HzMod crash the system upon loading HBL, and some versions cause the exact same crash.

Specifically...

• HzMod v.2017.05.05 has the exact same crash.
• HzMod v.2017.08.14 has a different crash.
• HzMod v.2018.02.04 causes the system to hang on the "homebrew" boot-logo
• HzMod v.2019.06.11 has the exact same crash.
• HzMod v.2020.06.06 has the exact same crash.

Additional notes:

• Luma3DS version: 13.1.2
• Rosalina Homebrew Menu version: 2.4.3
• I have not yet tested using a game exploit (with a digital title or a cartridge) to boot HBL, to see if this issue occurs in those cases as well.

As noted on Issue 11, the crash dump there looks pretty similar to the crash dump here. However I have yet to seriously analyze them, so it may just be coincidence.

It's additionally worth noting that the loader process is, of course, Luma3DS's reimplementation of loader, rather than the original loader of the 3DS's stock firmware. That may make debugging a little easier, but it also means it may be worth testing some slightly older versions of Luma3DS to see whether the same issue exists there or if it's some sort of regression on their end.
