(there was no r03 release posted to the WIP thread) byuu says: This should provide hardware-accurate mosaic support in the accurate renderer, with the exception that I'm still not sure what mid-frame vertical mosaic or mid-scanline horizontal mosaic writes do. Either the code I have is correct, or it bypasses the mosaic adjust and gives the exact H/V positions. I've also renamed the fast folder to alternative (thinking about naming it simply alt instead), and started on a brand new PPU renderer. So far it's just a barebones setup with some MMIO support and VRAM/OAM/CGRAM writing. I'm not even confident that I can get this to be faster than the current scanline renderer, but it's the only avenue that we have left for any kind of significant bsnes speedup, so I have to try. I'm going to finish up the MMIO stuff first, that way we have a clean slate with no actual rendering. And then from here we can try various different approaches.
