XaviX - ignore unaligned palette select bits in bpp modes > 4 (ttv_lotr boot screen) (#4213)
* ignore unaligned palette select bits in bpp modes > 4 * map some inputs in rad_ping (nw) * fairly sure these don't use Y index (used in ttv_mx road calcs, although still not correct) (nw) * dma IRQ allows ttv_lotr and drgqst to run further (nw) * name fix (nw) * change irq handling a little (nw) * timer notes (nw) * (nw)
