The game has a 217-index RNG at address 0x02. When it reaches the end, it cycles back to the beginning. Here are the RNG values, in order:
8, 66, 18, 148, 161, 13, 107, 89, 204, 101, 42, 83, 158, 243, 155, 218, 208, 130, 20, 165, 44, 98, 19, 156, 227, 31, 255, 248, 193, 14, 115, 159, 251, 217, 200, 68, 35, 25, 206, 117, 174, 118, 182, 176, 129, 12, 99, 27, 222, 241, 139, 94, 245, 170, 87, 191, 250, 209, 138, 86, 183, 184, 195, 30, 247, 186, 211, 154, 210, 146, 144, 128, 4, 33, 9, 74, 80, 134, 53, 172, 102, 50, 149, 169, 79, 121, 205, 109, 104, 65, 10, 82, 150, 177, 137, 78, 113, 143, 127, 252, 224, 7, 57, 207, 125, 236, 100, 34, 17, 140, 103, 58, 215, 187, 219, 216, 192, 6, 49, 141, 111, 120, 197, 47, 122, 213, 171, 95, 253, 232, 69, 43, 91, 220, 225, 15, 123, 221, 233, 77, 105, 73, 72, 64, 2, 16, 132, 37, 40, 67, 26, 214, 179, 153, 202, 84, 167, 60, 230, 54, 180, 160, 5, 41, 75, 88, 196, 39, 56, 199, 63, 254, 240, 131, 28, 231, 62, 246, 178, 145, 136, 70, 51, 157, 235, 93, 237, 108, 96, 3, 24, 198, 55, 188, 226, 23, 189, 234, 85, 175, 126, 244, 162, 21, 173, 110, 112, 135, 61, 238, 116, 166, 52, 164, 36, 32, 1
These numbers are not used in the RNG:
0, 11, 22, 29, 38, 45, 46, 48, 59, 71, 76, 81, 90, 92, 97, 106, 114, 119, 124, 133, 142, 147, 151, 152, 163, 168, 181, 185, 190, 194, 201, 203, 212, 223, 228, 229, 239, 242, 249
The RNG starts at frame 2 and advances once every 8 frames. The RNG affects what happens when you shoot an enemy, and the game checks it at the frame when your torpedo collides with a fish or sub. Divers sometimes are spawned when you kill an enemy. By paying attention to RNG values, you can control whether the diver spawns, and which side of the screen they spawn from, which saves a lot of time.
Thank you CoolKirby for adding my RAM watch file to
