A quick look at the bot's OLED screens, rendered live at 128×64. Wheel tests run and the mini-game plays — the same pixel buffer and geometry as the real device.
The real device, with the real two buttons. L steps to the
next screen within the active tier and wraps to screen 1 at the end of either.
R performs that screen's action — and on Credits it's the only way into
the Advanced tier.
Everything here is drawn the way the device draws it — same 128×64 pixel buffer, same 25-column text grid, same arrow and progress-bar geometry. Live values use representative sample data.
Mod_1 and Mod_2 are two pages from the Advanced calibration
tier, reachable only via R:Advance from Credits, same as on the real device.
