Getting to level 81 on Tempest (including the bug)
I used:
MAME 141
tempest1 ROM (must bug is fixed in version 3)
save states (Shift-F7=save F7=load 0-9=save locations) to get to lvl 24
end your game with a score of 183,x46 184,x46 or 185,x46
enter initials quickly (30 sec timer running)
WAIT until you see the TEMPEST title screen the SECOND TIME
press start - you can now start up to level 81 (shift-f7

My friends and I not being good Tempest players often play a start at
level 81 and keep continuing (down levels) until you can beat one and
that is your score

I'd be interested to know what level you can
finish
