Rosetta OS v0.6 + Rosetta Patcher

Rosetta Patcher for Windows: pick dumps of your own D-70's v1.11 EPROMs (IC4 + IC9, either order, or one combined 128 KB file; not included), and it builds D-70 Rosetta OS v0.6: two 27C512 images to burn (IC4 even, IC9 odd). Every build runs the full check set first (a few minutes). Keep your original chips; hold EXIT at power-on for the plain D-70.

v0.6:

• DLM page with a live view of the loop slice
• WAVE sweep through every wave with its name; EFFECTS page reloads the effects chip
• arpeggiator: up / down / up-down / random, 1-4 octaves, tempo, hold
• MIDI OUT page: key mode, split, velocity, per-section channel, program, volume, transpose, zone
• Alpha Dial in every menu, sliders keep working in the menu, KNOB LOCK (SETTINGS): slider 1 keeps the parameter it grabbed
• EFFECT/CTRL and MIDI OUT buttons open the Rosetta pages
• stock tone / rhythm / effector / MIDI / data-transfer screens cut (4 KB), their menu numbers open Rosetta instead
• Hex girl boot drawn at 2x

Do not share the built .bin files: they contain Roland code. Share the patcher instead.
