Description:	With this code, you can easily create a unique password system for your level. Define inputs that have to be done in the correct order and one of these things will happen: -Kill the player -Hurt the player -Give the player 1-UP(s) -Give the player a Power-UP -Give the player some coins -Give the player Star-Power -End the level (normal exit) -End the level (secret exit), triggers the keyhole animation -Spawn a sprite -Change ON/OFF Switch state -Activate P-Switch -Teleport to current screen exit -Teleport the player to the overworld, no event triggered -Teleport the player to a different overworld position Every option is very customizable, so make sure to change the defines in the asm file. V1.1 fixes - You can now define an unlimited amount of inputs and not only 10 - HUGE code optimization making the code about 200 lines shorter - P-Switch music now correctly plays - Sprites now turn into silver coins when using the silver P-Switch

Seems like changing the address loaded on lines 139 and 143 from $16 to $15 fixes the A button issue.

Can confirm, the "A" input does not work at all. This code needs a bugfix. Also why "A" or "B", shouldn't they be separated inputs? Same with X and Y. Why not separate inputs? This hurts the usability of this ASM a bit. Next version would be nice to fix that.

for some reason the "A" inputs don't work for me. All other inputs work just fine but nothing happens if I press "A". Using choice 12 if that matters

this will be VERY useful for me in a future, good code!

Tested with: LM 3.10, UberASMTool 1.4, SA-1 1.32, pixi 1.2.12, Snes9x 1.60.
Indeed a nice update, glad you fixed the couple of issues of the previous version and I saw a lot of improvements in the code. Also very nice that now you can define codes of arbitrary length.
As westslasher said you could also decrease the code for spawning normal/custom sprites since almost all of it is shared, but since doing this doesn't affect the insert size it doesn't really matter.

Seems like a very nice update, you can also shorten the code that you are using for custom and normal sprite spawning.

Example:

Code

if !spriteType == 0
;Normal Sprite
LDA #!normalSpriteNumber
STA !9E,y
else
;CustomSprite
LDA #!customSpriteNumber
STA !7FAB9E,x
;Add-in extra-bytes here.
endif
;x/y offsets go here.

Great! thank you!

Tested with: LM 3.04, UberASMTool 1.4, SA-1 1.32, Snes9x 1.6. The code works well and it has a lot of interesting options, so accepted.
I found a couple of small issues that would be nice to fix in an update: when enabling the PSwitch option, the song doesn't change. Also, for the silver PSwitch, you need to add a "JSL $02B9BD" to turn all the on-screen sprites to silver coins.

Besides that, it would be nice to make an update to optimize the code (it's not a major issue, but it could also be a useful exercise for you

). Right now you've encoded the different inputs with separate defines, so there's no room for expansion and there's a lot of duplicate code to check all the different inputs. A much compact (and faster, probably) way to do this could be to encode the inputs in a table (that could be expanded beyond 10 entries), so you wouldn't need to check !freeRAM for each possible value and jump to the different (but basically identical) subsections: you could just use the same code, pulling the correct value from the table using !freeRAM as the index.
