Greentea OS: Brew Hexa, Run .exe, Join the Vibe

Greentea OS is an alpha-stage, GPL3 desktop OS from scratch that boots from zero to Solitaire**.exe** in 2s+ on an average laptop.

Hey there, fellow programmer! I'm PeyTy, the guy who kicked off Greentea OS back in 2016. It started as a vision: what if we built an open source OS that runs .exe files like Windows, but feels like sipping a warm cup of green tea?

Or maybe like something that has a decent, fully GPU-accelerated compositor at 240 fps GUI, yet offers infinite backwards compatibility and speaks of software preservation without blinking?

Fast forward to July 2025, and we're in alpha — running apps like Solitaire, Minesweeper (including the very original XP version!) and a Calculator with a slick, as cozy as you want GUI. Now, we need you to help us brew something truly epic.

The reverse engineering (when involved) should occur under the relevant laws, to avoid any ambiguity and "religious" understanding of the reverse engineering approaches: some community members of other projects tend to abuse the "ideological superiority" of the chosen project, by bending, obscuring and twisting the processes.

Examples are notable comments by project leaders like Alexandre Julliard citation "You should not look at ReactOS code at all, a lot of it is reverse-engineered using methods that are not appropriate for Wine. It's not a usable source of information for us." - source https://bugs.winehq.org/show_bug.cgi?id=50464#c6

Such comments, historically, speaking from the shared experience of multiple contributors, tend to create a harsh "us vs them" environment for everyone, implying that the "other" project is somehow "bad by default" because it "does not follow" some obscure, unclear, never fully specified rules (even when it's completely unintentional and the rule authors a
