I just upload new version of all executables on sourceforge.
The source is uploaded also.
This new version 2.0 add the features:
There is two kernels of linux. The Old abi (Application Binary Interface) and new abi (gnueabi).
Tirwal, and others firmwares are Old ABI and TIGOR and BUGGINS are GNUEABI
These kernels are not compatible and the binary executable is different.
The dumb rule is: one executable works and the other don't work. Take the good one and delete the other.
The exit to bookshelf is fixed and now is possible run a program, exit and continue working.
Installation is easy. Just extract the zip folder on the root of a SD card and use Bookshelf to navigate. Then select gnueabi_*.exe.fb2 and if this don't work then the *.exe.fb2 must work.
Thank you and sorry for any inconvenience.
