m52: improvements to alpha1v (promoted to working) (#4223)
* m52 - use multiple palettes and regions instead of kludging into one (nw) * split alpha1v into different class etc. * with named regions these comments are redundant (nw) * (nw) * duplicated line by mistake (nw) * this seems plausible (nw) * fix sprite colours, looks like mpatrol could potentially support 3bpp anyway and the existing kludigng of the sprite clut prom was to save memory * mark it as working, I'm pretty sure 99% of the badness now is just the game * TODO note (nw)
