Used by the routine at main_loop.

| speed_score | 9CC2 | LD HL,($A24A) | Fetch current speed into HL | |
|
This code makes little sense.
|
||||
| 9CC5 | LD A,L | Speed low byte | ||
| 9CC6 | RR H | Bottom bit of H moves to carry (H now unused) | ||
| 9CC8 | RLA | Merge carry into LSB of speed (wrong end?) | ||
| 9CC9 | SRL A | Divide by four | ||
| 9CCB | SRL A | |||
| 9CCD | LD E,A | Needless move | ||
| 9CCE | ADD A,$00 | Add carry in, perhaps for rounding? | ||
| 9CD0 | DAA | BCD correction | ||
| 9CD1 | LD DE,$0000 | Zero high part of score increment | ||
| 9CD4 | JR increment_score | Exit via increment_score | ||
