Net Yaroze only provides a very limited background handler: - 16x16 blocks - fullscreen - non-scaling - non-rotating - non-semi-transparency (I think). Some people are trying to work around the 16x16 thing - and there has been success. There is an 8x8 handler from SCEI that displays a map at any screen co-ordinates and any size, but you'll have to make up the comments yourself. As far as I'm aware (and I've looked at a lot of these things), no-one has yet produced anything to get over the scaling, rotating and STP problems for 2d BGs. If you'd like to try, I think your best bet is with GsSPRITES and solid maths in for-next loops. Otherwise, you might consider building your background from 3d tiles. Loaded did this, and it has been done better in a very similar game on a recent PSM coverdisk (the name of which I can't bring to mind). If you find a solution - let me know!
