The needed sprites can then be read from this on every scanline, rather than having to parse the VDPs memory and generate the sprite each time it is drawn. It probably won't save a whole lot of time per scanline refresh, but when taken over the several thousand scanline updates per second that have to occur... If this is your first emulator, I found http://www.codeslinger.co.uk/ to be VERY helpful, especially with SMS graphics emulation. I believe he also has a gameboy section.

I'm writing an GameBoy emulator and I'm about to start working on the graphics emulation. I would be very be interested to read about the specifics of your sprite caching or any other sprite/tile based emulation optimisations. Thanks. Hi, nice blog you’ve got here.
