 This adapter builds on the ideas from the Amiga Denise adapter V2, adapted for use in big box Amiga video slots.
 
 The main differences are:
-- The 7MHZ signal is derived via C1 XNOR C3 using an additional 74LVC86 since 7MHZ is not available directly from the video slot
+- The 7MHZ signal is derived via C1 XNOR C3 since 7MHZ is not available directly from the video slot
 - Two button connectors allow for both a rear slot cover bracket button and another to be used, mounted wherever desired
 
 The card edge connector used is from Amiga-KiCad-Library (https://github.com/JustinBaldock/Amiga-KiCad-Library). Approximately 1mm of space is left between the fingers and the PCB edge to allow for beveling.
 
-## Recommendations for builders & resellers
-- To ensure the best possible picture on all Amigas, builders should include C6 (47 pf capacitor). 
-- V1.0 boards can easily be updated to include C6 by soldering the capacitor between pins 9 and 11 of the Pi connector on the bottom side of the board
-- Try the default software profile first, and if any glitches appear on the image update the software profile settings to include the below settings:
-    - Settings Menu->Overclock CPU: 40
-    - Settings Menu->Overclock Core: 170
-    - Sampling Menu->Sync Edge: Trailing with +ve PixClk
-- A heat sink on the Pi is also highly recommended.

 ## Version History
+- V1.1:
+    - Routing changes that eliminate "sparkling" on certain image patterns
+    - Excessive overclocking and the extra 47pf capacitor should no longer be necessary
+    - Make use of unused gates on the original 74LVC86 instead of adding another
 - V1.01 Added spot for 47pf capacitor (C6) to ensure no sparkling on image, and grounded unused inputs on U5 per data sheet recommendation.
 - V1.00 Initial version.
