Works with G510 now. Right-click mmoloader tray icon, check for updates, and select MQ2G510.dll.
It will be included in future compiles by default.
FYI, I really didn't do shit, yet - brainiac updated the SDK for G15/G19, so that it supports up to current keyboards (including the G510). I added a few preprocessor directives, so in future we can take advantage of any config differences - such as being able to control the 510's color.
Works as is, currently, using the currently configured color of your 510 lcd/backlighting via the logitech CC.
