  • Is a demonstration
  • Bankrupts three (3) CPU players after end of input
  • Manipulates luck
Recorded in FCEU 0.98.16, but works in v15 and probably in all versions.

You would think manipulating six rolls at once after end of input is impossible. Even BasicBot and the delay search program monopolysolve.cc would not work.
However, I found a solution.
The program used was monopolysolve2.cc. Given a starting point (9000 iterations from the beginning seed) and using a search distance of 100000, the program takes a random RndVal1 seed and tests, for all 256 possible RndVal2 values, whether it produces the six rolls necessary to bankrupt the three CPUs. Each CPU must roll either 3+3, 4+4, 5+5, or 6+6, followed by 1+1, 1+2, or 2+1 (but 3+3 -> 1+1 is disallowed). The program did output the following:
Done delay 5000
5 6 3 CB4129 5F 8039
Done delay 10000
6 4 3 390B11 8D 14372
Done delay 15000
5 3 5 ED528 D2 19135
Done delay 20000
5 4 5 CD8061 C6 20317
3 5 5 F8D5FC 54 22506

done
I took the first strategy, 5 6 3 CB4129 5F 8039, with a RndVal1 iteration delay of 8039.
After testing that the strategy worked (by using cheats to set up the CPUs, then poking the random seed values in), I constructed the run.
I wait at the name screen to manipulate three cards. Otherwise, I mess around while waiting. Rolling the dice is the fastest way to iterate RndVal1, but it also affects RndVal2, so I carefully set up RndVal2=5F, then spend enough time to get RndVal1=CB4129. These values appear three frames after the movie ends, just before RAM(27) increments to 1.
I may consider cancelling my other submission, but I will wait and see.
Thanks to the Monopoly competitors for the strategy, and thanks to everyone who contributed ideas.

Cancelled. Could be made cleaner. See submission #1186.
