Summary	04124: 19xx and clones: Bonus awarded for beating the final boss is wrong if time needed is over 4' 15''
Description	The game features a point bonus (also called "rank"): S(pecial), A, B, C, D and E, which is awarded to the player in accordance to the time spent for beating each boss (faster is better). In the final battle, if you spend too much time beating it (over 4 minutes and 15 seconds), the rank bonus awarded is still rank S and not the correct rank E. This is reproducable only in the last one, since all previous bosses escape sooner if they are not destroyed.
Steps To Reproduce	Destroy the last boss in over 4 minutes and 15 seconds

No.06879 AWJ Developer Nov 22, 2010, 22:15	This is almost certainly a bug in the original game. Can you test if it happens in the set "19xxj"? That set has a newer release date than the parent and other sets. It's possible that Capcom fixed the bug but only bothered to release the fixed version in Japan.
No.06880 Iaspis Tester Nov 22, 2010, 23:41	It happens in 19xxj too.
No.06881 ShimaPong Tester Nov 23, 2010, 15:15	It's original bug. If you destroy the boss in Stage 6 and 7 just before they suicide, you will be able to get maximum rank. Hi-score player already know and it will be famous among them so that you can see info about it even in the internet. The point-earner used by timer bug is known in some games, Alien Syndrome, Assult etcetc. Therefore, I ask you. have you investigated the walk-through for this game... for example game magazine?
