I'm glad it's helpful! Early on (while I was waiting for my device to arrive in the mail) I extracted the firmware factory recovery image (available from the manufacturer http://trimui.com/page.php?id=2) and ran strings and binwalk on the results. We found things like:

GCC: (OpenWrt/Linaro GCC 6.4-2017.11 2017-11) 6.4.1

and

Unix path: /home/<username>/Work/<username>/F1C100S_TINA/out/violin-F1C200s/compile_dir/toolchain/glibc-2.23-final/csu/abi-note.o

as well as library version numbers in the so filenames.

neonloop, the person who put together the toolchain, worked from there, with reasoning and trial and error. For those of us without your knowhow and soldering skills, discovering that the device has adbd was a huge productivity booster, giving us shell access to a running device without having to install a UART and the ability to push and pull files without having to remove and re-insert the SD card.

Another dev, eggs (who maintains the Dropbox folder), figured out a patch for SDL to fix the screen tearing just recently. He also figured out USB audio, how to initialize the LCD, and a host of other invaluable things.

I'm a novice when it comes to hardware and firmware hacking but I was able to put together a custom launcher that maintains the simplicity of the stock UI but updates the emulators and exposes their individual settings menus: https://github.com/shauninman/MinUI It's been a fun process of learning and discovery for everyone I think.

You should visit the discord, the other devs are much more knowledgable than I am
