This is a SNES arrangement of Team Rainbow Rocket's battle theme from Pokemon USUM, where the original was basically a remix of the original Team Rocket battle theme from Pokemon G/S/C (was also present in Pokemon HGSS).
This was VERY hard to do honestly; 3-4 days were spent just to make the samples and fit everything in the MIDI I used to fit the SNES's 8-channel limit, and then another 3-4 days to optimize and sequence this MML. I'm surprised this has worked so well tho, considering the sheer amount of samples and MML size that this port has, and the MIDI also had 13 channels, so it was kind of a wonder how it was possible to fit in everything (as you can see by how busy this port is); guess this is the true power of making chord samples lol
This could be used for a long boss fight, or a long chase sequence, but other than that, I dunno if this has many uses; and again, this port is really large, so use this with caution.
oh yeah, MIDI is by ShinkoNetCavy btw
Update: Fixed the tuning of the distorted guitar, and (hopefully) improved the mixing a bit.
