I expected the cat to fill a little more of the screen - can you double or triple it in size? Otherwise, a good start here. Needs the stars, too =P
The song itself is just what, a 3 second long piece plus a 27 second piece that loops over and over..... Is it possible to use the actual audio without pushing the rom over any technical limits?
I don't see why not - MarkyTheJester did looping PCM music in Jester's Challenge and it works in an emulator just fine.
Sir, I'll take your challenge. EDIT: Here we are and an mp3 for anyone who has/wants no business in SMPS binary files.
GenesisFan64 ok now combine the SMPS and the file you made and make the Nyan cat sprite bigger. Simple right?
v0.2 - Now using MarkeyJester's song port - STILL NO BG BECAUSE I'm TOO LAZY I CAN'T FIND A CATLESS GIF FOR THAT kthx oh and don't hold B and C at the same time and soft-reset, just don't. + - (first time making a humorous post) Source code... later if someone wants to finish this, because I got tired.
If you want, you may send me your source code to me. I may add some things with C. + - Hey, this ROM was originally a test one? . Oh, and also, nice joke for the MD's BIOS. Oh, and the "IT'S MAGIC" screen was awesome too.
I've recently seen a Hank Hill version of the Nyan Cat theme (Nyer). Maybe a Boomhauer-copter boss? It's up to you, it's your hack.
