You can't convert, you can actally save a value stored in RAM to SRAM, like this:
You'll load RAM $58 and save the value in SRAM $700080.
EDIT: LEVEL UP!

I'm guessing the next part is guessing what's used and what isn't.
Either way, thanks.

IIRC, you can use SRAM addresses from $700800 onwards. You'll have 131,072 bytes of free SRAM if you expand your ROM's SRAM size to 128kb (which can easily be done by changing PC [x81D8] to 07).
It may be worth noting that most if not all SRAM addresses are initialized to $55 by default, not 00.

Well, you can use the SRAM for saving things by using a patch called SRAM Expand, you can choose which RAM will be saved and what's the size of the SRAM.
And by the way, RAM is initialized to $55 and SRAM is initialized to $60 not $55.

Except in the later versions of bsnes (I think 0.80 and newer, but it might be 0.82 or something), where regular RAM is initialized to random values...and I don't know what SRAM is initialized to, but it is presumably random as well.

Ok, so when I go to use the sRAM, I have it set the sRAM I'm using to whatever value I'm going to use as "locked" when the player starts a new save file, and then have it save that sRAM to the "unlocked" value whenever the player unlocks that item, right? Ok. I think I understand this a little better. Thanks guys.
EDIT: Different question. Didn't want to double post.
Is CODE_00F5D5: A5 19 LDA RAM_MarioPowerUp ; \ If Mario is small, kill him a good place to hijack for a HP patch?

I'm trying to implement the Koopaling fixes described here (http://smwc.hostzi.com/SMWiki/wiki/Koopalings.html) via a hex editor (0xED on Mac).
I set 0x1DF6E to [84 CC A4] and 0x1DF73 to [B3 B3 B2]. I think so anyway, I don't see the "0x" part anywhere.
But for "Lemmy's palette can be changed from yellow to green. In the range of addresses 1D42E-1D49C, the lower digit of each byte that ends change in 5 must be changed to B, while leaving the higher one as it was. To make Wendy use a pink palette instead of the red one, in the range of addresses 1D4B8-1D526, each byte with a low digit of 9 must be replaced with F."... I'm not sure what a lower digit is. What I ended up doing was change all the 05 in that range (for Lemmy, for example) to 0B. Broke a few things when I tried to test it.
Can someone either guide me in the right direction, or be super nice and create a patch with these changes already implemented?
Thanks,
|

Yeah... there are countless errors there. First of all, there is not even an org $xxxxxx where your code will be placed, DEX #$03 does not exist, db is completely static (it won't change at run time), and doing org $xxxx like that won't work since it's static as well.

QuoteDEX #$03 does not exist, I should just DEX DEX DEX instead, right?

Wow, that is... haha. Good to know that won't work. Looks like I'm going to have to find some other way to change the player's behavior at runtime.

I'm pretty sure this has been asked numerous times, but how exactly do I draw tiles to the status bar? I was planning on using a loop to do it in comparison to freeRAM.
...
I was planning on doing it this way so I wouldn't have to use super huge tables or anything.

Where I can get button addresses? I can find them at all.

Check these addresses:
| $7E:0015 | 1 byte | I/O | Controller data 1. Format: byetUDLR.
b = A or B; y = X or Y; e = select; t = Start; U = up; D = down; L = left, R = right. |
| $7E:0016 | 1 byte | I/O | Controller data 1, first frame only. Format: byetUDLR.
b = B only; y = X or Y; e = select; t = Start; U = up; D = down; L = left, R = right. |
| $7E:0017 | 1 byte | I/O | Controller data 2. Format: axlr----.
a = A; x = X; l = L; r = R, - = null/unused. |
| $7E:0018 | 1 byte | I/O | Controller data 2, first frame only. Format: axlr----.
a = A; x = X; l = L; r = R, - = null/unused. |

Hello,
I have 2 noob questions...
1. how can I spawn (in a block) a "bounce block sprite" (at the position of the block)?
2. how can I spawn a "score sprite" (like the "1UP")?
I have found soe things in the ROM Map but that doesn't help me
I hope you can help me

Two questions:
-What would I have to do to get the game to save upon entering specific levels of my choosing (LevelASM?)
-Is there a way to notify the player of how much Yoshi Coins they have collected in a specific level?

You could attempt to save the number to a location on the status bar. To do this, use this code:
Where $XXXX is the status bar address. Possible values are:
