We are glad to anticipate the release of the Lizard Toolbox, the PC application that will be the companion of Maximus Lizard when used attached to a PC. The functionality of this application is to receive the files that are read with lizard and also serve the patched files (custom FW) to lizard for drive writes.
We have added a tab "CFW Generator" whose function is to generate the patched firmware from the file you read with the device, pretty much all that is needed for a really quick job. Please read the attached readme.txt file for general information on how to use it. We will post proper tutorials really soon.
Lizard Toolbox (from now on TBX) will be very useful in the meantime while the Stand-alone mode is released. Its important to consider the Stand-alone mode will be releasing in stages after launch date. We will go 1 drive and 1 feature at a time, we will start with the most popular drives at the moment. Remember lizard will have the possibility to upgrade anytime its firmware so your investment is protected. People worried about 0225 key reading, I guess they missed our launch video long time ago 
Consider the TBX application as Beta and even when you don't have a lizard yet you can help us testing the CFW Generator, we will appreciate your feedback and suggestions, error reporting, etc.
Last but not the least we want to make clear we are not taking credit for custom firmware at all, all credit its and remains to c4e.
