-----------------------------------------------------------------------------------
To do:
- lordgun: in the 3rd leg of the ship stage, sometimes part of a far jetboat is drawn above a nearer sub (both sprites).
But this is correct considering both priorities and sprite list positions. Original game bug?
- lordgun: wrong colors for tilemap 0 in the 2nd leg of the last stage (where some sprite priority bugs happen too)
- lordgun: in the jungle level, final enemy, tilemap 0 does not scroll. It may have wrong priority, or may need to be
disabled, even though it is used by enemies to hide, so it's probably just odd but right after all.
- aliencha: no info on the PCB (clocks, chips etc.)
Notes:
- aliencha: when booting into service mode, keep buttons 1, 2 and 3 pressed to show more options
- aliencha: original videos at http://www.youtube.com/watch?v=TRHb3WTGuvk, http://www.youtube.com/watch?v=_RaCpHwyS78.
The latter shows English text and a 1995 copyright (instead of 1994) in a different font.
- aliencha: routine at A34 - english/chinese text, A38 - english/chinese names, A3C - Alien Challenge/Round House Rumble title
