History:
1.0 : Added DS tracks and battle arenas, replaced Donkey Kong JR. by Donkey Kong, working CPUs.

1.1 : cosmetic changes i think??

1.2: FIXED!!!!!!! i resolved the jump issue! Actually it's because my "unmodified" SMK rom was actually saved through epic edit, with no track changes but epic edit adds patches anyways. the old download is still included of course. I'm working on 2.0, which will eliminate... or at least attenuate the very small tracks, i'm remaking them from scratch. Very slowly. Very VERY slowly. But I finished 4 tracks as of me writing this (17th of february 2022). here's a comparison image: https://data.nimages.fr/oldvsnewcheepcheepbeachdjx.png
