CMD is the command prompt, which can be used to run applications. *Copy* cmd.exe from C:\Windows\System32 into your folder

Copy and paste cmd.exe into the folder, open it, and type "xkas.exe patch.asm rom.smc", without quotations. This is to apply an asm file that is a *patch* to your ROM, using xkas. However, you'll want to point the patch to free space, which should be outlined in any xkas tutorial in this forum.

What exactly do you need help with? Be specific otherwise we won't be able to help that much.

Also, do note that there are other ASM tutorials floating around. You should try them out too if you don't get this one (you can find some in the Tutorials Section of the site and some in this forum).

So... What would I have to put into the code if I wanted to implement ON/OFF blocks into a block? As in I want the block I am making to react to the ON/OFF Status.

You probably shouldn’t waste much more time. You wouldn’t want all those nice depleted steak isotopes to settle down.

The address that controls the ON/OFF status is $14AF, so just create a branch statement depending on that:

Code

LDA $14AF BEQ SwitchOn ; this code is executed if the switch is off ; make sure you have a return statement here, ; or the SwitchOn code will be executed ; even if the switch is off SwitchOn: ; this code is executed if the switch is on

Well after:

Code

LDA $14AF BEQ SwitchOn

I want to load Mario's x Position, so would I have to LDA again as the start of the next part of the code?

Example:

Code

LDA $14AF BEQ SwitchOn LDA $7E ... ...

Yes? No?

It should be

Code

db $FF,$FF,$FF,$FF

.

This isn't really the place to ask that, though; this thread or this one would be more appropriate.

You know... this tutorial is extremely outdated =/

I think we should either update it to work with xkas and btsd, or simply close this and put focus on imamelias tutorial.
