making a one level demo?

Well As I was working on my Hack a bit, I was trying to see how can I make it to where it's playable for just the first level. Kind of like in S1ZX for instance in which only GHZ was playable as a demo level. I was wondering If possible would I have to disable certain parts in each level or just for GHZ itself in the main asm file?

 

1) Disable the Level Select.


2) Add a check for when the area for what you want finished to go to the Sega screen or something.


3) If you need to, remove levels.


And that's how I'd see it. Though the last part isn't needed, it'll combat a certain PAR code that allows precise selection of the level, but it's not that important for casuals.

 

I tried the 2nd option and it worked, Thanks a bunch dude.
