So, a great verdict overall! Except for a tiny bit of confusion.
It works with the TerraOnion MODE as a *.IMG + *.CCD combo (just like Ghost Blade for instance), spare the fact that you have to re-scan the containing folder and then restart the system once for the ODE to be able to recognize the image.
It boots perfectly onto the language selection screen, and plays the game nicely if you decide to start a game quickly or change the BMG. This is because a loud distorted noise can be heard a few minutes into the intro track while waiting on the main menu.
Note: All the other tracks play perfectly fine though off of the BGM test option (AREA_2_FACILITY ROCKS HARD AF BTW), and the game cover art can be seen on the MODE game list.
In conclusion, I think that you should go ahead and flaut this great upload with a fresh thread of its own 🤘
