a real PCB to find the difference.
Currently it beeps every time a player eats a dot. Seems right.
2. If "Hard" mode is selected, numerous bugs appear which
could be either an emulation fault or a bad rom. Some
bugs are:
a. Graphic error halfway up the left side
b. Score adds or subtracts random amounts
c. Score not cleared when starting a new game
d. Game begins on the wrong level
seems to be an emulation fault. Every revision we have
shows the problem, whereas the real hardware works fine.
- You start with 9000 points (instead of 0).
- On the screen where you are awarded your Bonus, you will
instead get (or sometimes lose) a random amount.
- At the end, if you got the High Score, it could be changed
to something else.
All these bugs can be cured by a simple 1-byte patch:
ROM_FILL( 0x47e5, 1, 0xc3), but why is it necessary?
- Space Chaser (schasercv)
These cheats exist in this game:
1. Hold down 2P DOWN (the F key) while it says INSERT COIN. Then
insert a coin and play. You will have 2 extra ships.
2. In the Hard difficulty setting, you normally start at level 4.
Hold down the 1P START (the 1 key) while it says INSERT COIN.
Then insert a coin and play. You will start at level 5.
- Space War (Sanritsu)
* I seem to recall that the flashing ufo had its own sample
