I was just updating my isomount to support autorunnable chroot ext2's and used this BosWars as one of my first autorunnable ext2 chroots.

Basically it puts the whole game in a single file you can run off an mmc like a rom.

You will need isomount v.1.0.3 and dbus-switchboard v.1.2.7 and then download the BosWars ext2 file (gzipped), extract it and click on it from file manager to run. Emelfm2 can extract it or extract on desktop to get the .ext2 file to put on mmc. Its a 76meg archive of a 100meg file so i kind of needed to compress it.

If you plan on running any autorunnable iso's you'll also need penguinbaits cdrom driver (for iso9660 filesystem support)... but BosWars is ext2 which maemo has built in support for so not needed for this.
