Image_blit
BlitBeyondWidth
Demonstrates the interaction between 0x9F image blit operations and assigned GPU tiles. A blit operation is configured with a target smaller than the source. The target address is set within an active GPU tile such that the blit would extend beyond the end of the tile and a guard value is tested to prove that the blit is clipped to stay within the tile. A similar blit is performed outside of the tile, demonstrating that unprotected blits may overdraw the target region.
BlitRenderBlit
Blits an image into a render surface, then performs a 3d render on top of the surface, then another blit on top of the composited two. Finally does a srccopy to blit the finished composition to the framebuffer. Demonstrates apparent incorrect ordering in various versions of xemu.
DirtyOverlappedDestSurf
Performs a 3d render into the backbuffer, then a 2D srccopy that completely overwrites it. Finally performs another 3d render, demonstrating incorrect behavior in various versions of xemu.

Overlap_BL_Inside
Tests the boundary condition of xemu's 2D blit overlap detection by performing a 1x1 pixel blit exactly inside the bottom-left corner of a 3D render surface.
Overlap_BL_Outside
Tests the boundary condition of xemu's 2D blit overlap detection by performing a 1x1 pixel blit just outside the bottom-left corner of a 3D render surface.
Overlap_BR_Inside

Overlap_TR_Outside
Tests the boundary condition of xemu's 2D blit overlap detection by performing a 1x1 pixel blit just outside the top-right corner of a 3D render surface.
OverlapFIFO
Demonstrates that image blits overlapping the pushbuffer are performed without issue on HW. A blit copying the test image over the current pushbuffer write address is queued, followed by a blit copying the data from there to the screen. This is flushed to the HW, along with a wait until the pushbuffer is fully consumed. Failure to wait demonstrates a race between the blits and subsequent instructions, generally leading to some corruption near the top of the image.
