hmmmmm, seems looking back on the tutorial if you choose the overhaul option the avalanche GUI doesn't work. Is there anyway to just untick that option and install the other GUI, or do I have to "reinstall" everything using the bootleg again?
If you're new to here, then you probably don't know that it does work. The incompatibilities between Avalanche GUI and Menu Overhaul are a few slight misalignments with the menu texts. Apparently the textures are slightly enhanced as well, but it seems it may be the opposite. I never looked closely for white lines, and can barely see them in your screenshots.
Anyways, you can run Bootleg again and install Avalanche GUI just fine. The game will look
almost perfect, but nothing blatantly out of place. For example, check the Save Slot menu box in the top-right corner when you're going to save/load a game.
