MEGA MAN X2: MMX2 Skip Intro with Assembly

Simply skips the introduction/reploid factory stage and goes directly to the boss/stage select screen similar to classic NES Megaman.

Assembly file is also included.

ASM file can be used to load a specific level from startup screen and run it an infinite number of times.

Apply patch to a Megaman X2 headered rom. Recommended to use Flips for patching.
The assembly file is included (but not required). Recommended to use Asar for assembler.
This patch will also work for Rockman (J) X2 headered, since the address locations
for the patch are the same.

Function
----------
Simply skips the introduction/reploid factory stage and goes directly to
the boss/stage select screen similar to classic NES Megaman.

Why is this useful?
If you'd prefer to just edit the regular stages and the Sigma stages
and you think the intro stage is a nuisance then this patch is for you.
Or if you'd rather just get into playing the game without the introduction.

Assembly
---------
Hacks the assembly to load default level 1 after the reploid factory stage
and changes a value to record that the introduction has been finished. If you
run the game without the second instructions the level runs in an infinite
loop (like the intro stage).

How to Edit
------------
The assembly is very useful if you'd like to edit only one of the levels
for the game and load ONLY that one level. Since you need to defeat the intro
to get to the stage select screen you will infinite loop on whatever level
is loaded, both after you expire your 2 lives, or even if you defeat the
boss for that level, if you remove the second set of instructions.

Comment out this code (using semi-colon):
org $9675
ldx #$04
nop
stx $1FD2

You can also change the level ID to start the game from any level, just change
the value in the first set of instructions.
