			0x18: PV seems good, audio good, chart and score broken? -- timing resets, notes don't
			0x14: PVs a little bugged (not major), chart and scoring fine, life still doesn't reset
			0x10: life resets now, but old graphics don't clear

			0x15: same as 0x14
			0x16: doesn't actually reset????
			0x17: crash
			0x12: like 0x10 but life isn't cleared

			case 0x11 seems to clear life
			case 0x15 seems to clear score (maybe note data)
			case 0x18 seems to fix timing

			patch 0x15 at 1401038cd (was 0x12), 0x18 at 140103b94 (was 0x16)
			then call with 0x11
			hopefully it'll work

			percentage doesn't fully reset by the looks of it????
			rip
			(actually was hold and slide scores -- fixed by manually clearing them now)
