Umihara Kawase Christmas Community Challenge hack
« on: December 22, 2019, 11:07:12 PM »


It's the 25th Anniversary of the SNES game!
We started a collaborative ROM hack at the Umihara Kawase Discord a few weeks back and now it's done.
The IPS patch is here: https://www.dropbox.com/s/hk5sdfpdc8t9rbe/Umihara%20Kawase%20Christmas%20Community%20Challenge.ips?dl=0

I tried to squash all bugs I could find but if you've got something, let me know in this thread.
Be sure to play all the way to the end, there's a very special surprise and I hope you like it!

Thanks to all collaborators.

EDIT: unfortunately, sometimes the game crashes in the final boss, right as the tadpole jumps into the water. The best way to mitigate the crash is to not be onscreen with them once this happens, and instead just holding up in front of the door right when you know you're going to win.

Great job, field 2 is my favorite. The new graphics are great too. Seeing the boss lay frogs is hilarious ;D and ironically enough his hitbox seems closer to this new sprite

I've been itching to use that secret tech from umipasta for a while  ;D

Right. So, long story short, I have a Super Famicom again and a flash cart.

I've built the ROM with LIPS, gets an MD5 checksum of 5591e3bb07acecbbec2c3fb3294904b9.

This seems to run ok on bsnes, but when I run it on real hardware it hangs after the menu - I can start a game and the music kicks in, but the level never shows.

Any ideas?

To answer my own question, you need to change $7fd7 from $0a to $0b (a = 8mbit, b = 16mbit), the header incorrectly identifies the game as 8mbit and that causes the flashcart issue. This is a general issue with any ROMs made by Riverback.

But now I've done it, and played it, and it's great! Well done everyone. Especially amused by the boss.

Hi! I was wondering if there are any plans to make more community ROM hacks? I've really enjoyed the hacks that I've found from this site and I'd be delighted to play more of them.

My apologies if this thread is the wrong place to ask.

Hey there, Combi~ringer.
There are no plans currently but I suppose if there's enough interest we could make a new one, bigger and better than the last  ;D

If mappers are needed I would like to be a part of it
