How do I get unstuck when I never got the downward or upward thrust?

Solution 1:

I did some testing on my end and discovered the memory address for thrust is

 0x0796 

Apparently a hex value of 00 (Dec 0 )means that its disabled. And a hex value of 10 (Dec 16 ) means that's it's enabled.

So just use your emulator program to modify the above address to this value and you will be able to downward thrust.

Further testing shows that a hex value of 14 ( Dec 20 ) will enable both downward thrust and upward thrust.

To make this even easier if your emulator supports pro-action replay codes ( most do). The below codes will work.

0796-10 - For Downward Thrust Only
0796-14 - For Downward & Upward Thrusts
