Note: The script is not very fast, it may take up to five minutes (at max_attempt=999999) to finish. It will freeze Bizhawk in the meantime

For Famidash v1.2.1+. Does not apply to v1.2 and earlier.

This script tells you, starting with an RNG value either specified or read from memory, whether Lucky Draw will eventually be successful within "max_attempt" loops (modes 1&2), or alternatively whether the first attempt is successful or fails a particular check (modes 3&4).

mode 1: Starting with initial RNG given below, determine whether Lucky Draw will eventually be successful within "max_attempt" loops, and how many attempts it takes.
mode 2: Same as mode 1, but with RNG value read from memory address 0x1B (4-byte little-endian)
mode 3: Starting with initial RNG given below, determine whether the first attempt is successful, and if not, which of the 788 checks it fails, and the final RNG value upon death (this RNG value is the value for the next attempt).
mode 4: Same as mode 3, but with RNG value read from memory address 0x1B (4-byte little-endian)

This script tells you, starting with an RNG value either specified or read from memory, whether Lucky Draw will eventually be successful or end in an infinite loop (modes 1&2), or alternatively whether the first attempt is successful or fails a particular check (modes 3&4).

mode 1: Starting with initial RNG given below, determine whether Lucky Draw will eventually be successful and on which attempt, or end up in an infinite loop and state which attempt repeats which attempt, and what the RNG value is when it repeats.
mode 2: Same as mode 1, but with RNG value read from memory address 0x1B (4-byte little-endian)
mode 3: Starting with initial RNG given below, determine whether the first attempt is successful, and if not, which of the 788 checks it fails, and the final RNG value upon death (this RNG value is the value for the next attempt).
mode 4: Same as mode 3, but with RNG value read from memory address 0x1B (4-byte little-endian)

A Lua script that converts passwords to levels, levels to passwords (both "Sonic 1 cart" and "non-Sonic 1 cart"), levels to stages and stages to levels. This wiki site, this online level/password generator, and this description of the algorithm for encoding and decoding passwords, have some more details about how the level generation works

This Lua script uses Lua 5.4 bit operators and requires BizHawk 2.9.1 (or standalone Lua 5.4)

This is a small Lua script which is used for Mega Man games that use the "MMX RNG". In case you don't know what I mean by this, it's a 16-bit period-43534 RNG starting with the value 0xD37 and governed by the following formula:

local function nextrng(rng)
	local rngh=(math.floor(rng*3/256))%256
	local rngl=(rngh+rng)%256
	rng=rngh*256+rngl
	return rng
end

This Lua script uses a reverse lookup to display the index of the RNG (0xD37 = index 0, 0x275E = index 1, etc.).

This Lua script also displays the R-F value for X-X6, which is (RNG index minus current framecount) mod 43534. When inside a stage, a ROM subroutine auto-runs the RNG at one cycle per frame without using it, so this value can be used to detect unusual RNG advances which *are* used by the game. MM7 has similarly a "R-2F" value (since RNG runs at two cycles per frame), whereas R&F does not run the RNG except when needed and so does not need to display such a value.

This Lua script also displays the current RNG value, the 3 RNG values before it, and the 6 RNG values after it.

Displays the index number for RNGa and RNGb. Reverse lookup for RNGa and 139*value mod 256 for RNGb. Might need to raise "max_number" value if not enough RNGa values.
