Manual gives all setup to upload a palette from the host. But nothing forbid to render directly in the palette buffer. (GS rule nb 1, there is no rule ^^) Fix Virtua Fighter 2 dark colors However I'm not sure we can fix HW renderer. Rendering is done on the GPU but palette handling is done on the CPU... So we need to read back data (ouch, and slow). A quick test didn't get the expected results. Potentially there are others bugs (aka not gonna happen on the HW renderer)
