A new version of GPS Tuner 6 is going through the beta test process (the public beta of which ends Monday), and the Regular Build released in a few days after that.
The new version of the program will be renamed GPS Tuner Atlas, so as to differentiate it from the previous version.
The new version will be a free update to existing users of GPS Tuner 6, so those users have good reason to rejoice, because this program is soooo much better than the previous version.
GPS Tuner Atlas should remedy most every bug that prevented users from making full use of the initial program, and also make it compatible with older devices that did not support the Direct 3DMobile API that the original program was written for.
