A few tools for game development using Marmalade and IwGame
You may find more information about these tools at http://blog.yjpark.org/
This is a simple tool to convert Cocos 2D Font / BMFont to Marmalade's GxFont format. run it like (use --help for more details):
marmalade-font-tool -c -f gen/fonts -t data/fonts -n Dialog
the -f param specify where to find the original font files, the -t param specify where to save the converted files, the -n param specify the font name (in this example, supposed Dialog.fnt and Dialog.png exists under gen/fonts folder). If the converting was done correctly, Dialog.gxfont anb Dialog.tga will be saved under data/fonts folder.
PIL is needed to run the converter, you can use pip install PIL to install it. (of course you can use easy_install as well, though IMO pip is much better)
