Notes
from Kold666:
I noticed that mame misses completely some sprites that are present on the pcb. On all levels there are red enemies riding horses and you have to hurt them to make points.
That's why the game is so boring in mame! ;)
Also as I already said on the mametesters forum, the pcb has some serious sprite lags, sometimes obstacles desync comparing to the speed of background (they seem to move ;) ) and there are many slow downs where there are many sprites at the same time.
On the main board there is a 13.4mhz osc, on the second board (sprite? if I disconnect it I can't see any sprites) there is a 4mhz one.
Roms 12 onward are on the second board.
EPROM content is the same as in MAME, it is split in half size chips. This should be noted in the driver.
