This release has been built on Linux Mint (a Ubuntu derivative), using Vincent Rivière's GCC 4.6.4 cross-compiler. The custom tools used in the build process were built with native GCC 4.8.4.

The source package and other binary packages are available at:

The extras directory (if provided) contains: (1) one or more alternate desktop icon sets, which you can use to replace the builtin ones. You can use a standard resource editor to see what the replacement icons look like. To use a replacement set, move or rename the existing emuicon.rsc & emuicon.def files in the root directory, then copy the files containing the desired icons to the root, and rename them to emuicon.rsc/emuicon.def. (2) a sample mouse cursor set in a resource (emucurs.rsc/emucurs.def). This set is the same as the builtin ones, but you can use it as a basis to create your own mouse cursors. To use a replacement set, copy the files containing the desired mouse cursors to the root, and rename them to emucurs.rsc/emucurs.def. For further information on the above, see doc/emudesk.txt.
