Compilation error
I followed the guide from https://devkitpro.org/wiki/devkitPro_pacman to set up the build environment. Then I cloned the repo and tried to compile romsel_aktheme, but got these errors. I tested on both Arch Linux and Windows MSYS2, the errors are exact the same.

One of the errors was complaining IO_VRAMCNT_A is missing, but it is in io.h and io.h is included by vram.h. So I don't think the headers are actually missing.

What did I miss? Should I set EXTRA_CFLAGS or something to assign more include paths for compiler to be able to find the headers?
TWLMenu++ is not compatible with libnds v2 and calico. You need to downgrade libnds to a version before 2.

Thank you very much for promptly pointing out the issue.
So I uninstalled libnds 2.0.1 and also libfat-nds 2.0.2 and maxmod-nds 2.1.0, both of which depend on libnds, so they have to be uninstalled as well. THen I compiled libnds 1.8.3, libfat 1.2.0 (only nds libs) and maxmod 1.0.15 (only nds libs). Now my files under /opt/devkitpro/libnds looks like this

I search around, it seemed a thread also reported this issue https://devkitpro.org/viewtopic.php?t=2005, but about 15 years ago. I don't quite understand the solution though, as the tool-chain is suppoedly up-to-date, except libnds, libfat and maxmod. It looks like the __irq_flagsaux is in the linkscripts, but I don't know how to solve this.

Could you help identify the issue and how to fix?
I'm not familiar with the error, but devkitARM may also need to be downgraded to a version before libnds v2. Try running make clean first and then run make again before downgrading devkitARM.
If the issue persists, then idk how to fix it.
Surprisingly, I actually managed to complete the compilation by using this solution:
I replaced ldr r0, =__irq_flagsaux in libnds-1.8.3/source/common/interruptDispatcher.s with ldr r0, =0x04000000 - 0x40, so the symbol of __irq_flagsaux no longer exists.
Then I further downgraded libfat from 1.2.0 to 1.1.5, as I found out the source code is checking libfat's version to be exact 1.1.5.
After that, no errors again.
the compiled romsel_aktheme.nds doesn't work on NDSi, it freezes on white screen. Anyway, I give up.
This is everything that upgraded on the day libnds 2.0 was pushed, and the versions I use for building this. It's probably not necessary to downgrade everything back to pre-2.0, but I don't build anything newer anyway so it's probably 'safer' to revert the environment to before 2.0 entirely just to rule out potential compatibility issues.
default-arm7 0.7.4-7 devkitarm-rules 1.5.1-1 dswifi 0.4.201 libfat-nds 1.1.5-1 libfilesystem 0.9.14-2 libnds 1.8.3-1 maxmod-nds 1.0.15-1 nds-cmake 1.2.1-1 nds-examples 20200727-1
~~I'm also on devkitARM r65-1 if it matters~~ r66 works
Find what you need here if the old package versions aren't already in your paccache from before. Use pacman -U [filename] to manually install from .tar.xz or .tar.zst packages
You can also use docker which will use the correct version of the toolchain, but if you were trying to build your own changes I don't necessarily know how easy or not it would be to do that using docker. I can't imagine it wouldn't be possible though, so it's worth looking into.
