Since Blueretro version 1.8.4 has been released, and since I hadn’t yet integrated the small specific changes made to Methylene in the official repo, I had to make a new version and re-flash the STANDALONE Methylene cards.
In theory, shipments will take place on Wednesday August 16.
Please note that if you have already downloaded and flashed with the version made available, I advise you to flash the new version via USB. A bug in the image name of the Methylene version may prevent subsequent OTA updates.
