I have created new thread for more people to see it, but the thread somehow disappeared, so i'm posting this here:
Made a small program for packing/unpacking resource files(WatchFace.exe used from first post). You need .Net to run it
How to unpack:
1. Drag and drop the packed resource file with .bin extension (~ 1mb) onto mb4_resource_tool.exe
2. Next to the packed resource file, the unpacked file with .res extension (~ 3.5-4mb) should appear
3. Drag and drop the .res file onto WatchFace.exe
How to pack:
1. Drag and drop the resource folder onto WatchFace.exe
2. Drag and drop the file with .res extension (~ 3.5-4mb) onto mb4_resource_tool.exe
3. A ready-to-flash packed file with the extension .bin (~ 1mb) should appear
