This patch adds a world select menu when starting SMB2J.
Make sure to only choose files 0, 1, 2 or 3, any other files will likely just crash the game.. But that's half the fun.
Usage:
- Press select to switch between lines
- Press Left or Right to change values by 1, Up or Down to change by 16
- Press B to save your selections to disk
- Press Start to start the game!
- Press Start+A to start the game with the hard mode flag set (doesn't do much except change how the level name is displayed on the title screen.)
The 'file' behavior is a little weird, so if you want to match the original game:
- If you want to play 1-1, select File 0 and pick World 0
- If you want to play 5-1, select File 1 and pick World 4
- If you want to play 9-1, select File 2 and pick World 8
- If you want to play A-1, select File 3 and pick World 0
A couple of extra things to be aware of:
-
The selectors are 0-based, so if you pick world 0, area 0, you will get what's normally 1-1 (the title screen will show 1-1.) This was done to make it easier to remember level numbers rather than having to remember that you were on "right side of a cloud - copyright sign"
-
The 'area' selector picks areas not levels. If you play a stage where there's a pipe entry cutscene, it is it's own separate area. This way you can access every single area but the numbering can be a little off.
First, download the latest patch from the releases
Then simply apply that IPS (using for instance Lunar IPS) to the original, unmodified version of the "Super Mario Brothers 2 (Japan).fds" ROM without an FDS header.
The MD5 checksum for the ROM you should be using is 7f38210a8a2befb8d347523b4ff6ae7c.
You will have to use the "patch-fdsheader.ips" file instead of "patch.ips" if the system you will be running the game on requires an FDS header (like the Powerpak.) Unfortunately you will have to test one first and see if it runs, if not, try the other!
Have fun!
