Here is the source.
It is a little different to the 0.5 ipk as I've added the option to rotate to 0,90,180,270 degrees since that release.
I'm experimenting with drawing the tiles the correct size to start with so that there is no resizing of bitmaps to do. I haven't finished that but I think I've taken all of it back out and got it to a reaonably stable state.
I use the .pro file to build for qvfb on my laptop, .zpro for Sharp ROMs and .opro for opie builds. They each produce a Makefile, ZMakefile and OMakefile resp. The opie stuff is a bit ad hoc since I've broken my opie build environment (actually it got out of date and I'm on dial-up so I haven't been able to get it properly up to date).
Let me know if you need any help to get it to build (timwentford AT hotmail DOT com).
One thing has occured to me which could be part of the trouble. I cheat with zlib and just use the version embedded in liibqte rather than an external one (you need to copy (IIRC) zconf.h and zutil.h to the zaurus includes directory). This doesn't work on opie because zlib isn't embedded into qte for opie builds - maybe something like that happens on the 6000? If opie-reader works on the SL6000 it is unlikely though, since I do the same trick there.
