Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.
This patch lets you remove the COURSE CLEAR scorecard and/or the zooming circle effect at the end of the march.
What's removed is editable in the ASM file. However, the palette fade will always be removed.
Good fix. It's great alternative to original SMW "Course Clear". I find it odd that after defeating Mode 7 bosses scorecard doesn't appears on screen (if enabled obviously), but that's probably just design preference (or limitation).
Ive had some problems with Reznors after applying this patch. The music/whistle keeps looping and it never ends.
I must note that it was the final boss, and should trigger the credits.
Not sure if it was related to this patch, but might worth checking...
*** Apparently freezing sprites after beating the boss solved the problem
