Hello i'm new here in this forum but i am a old user of OCREMIX(since the origins of this site ;D)
I love specially orquestral and tecno remixes, but i think you need more Jazz and Blues, specially for Nes remixes. I give you some example of great compositions who never are remixed here, perfect for a Jazz/Blues remix:
Duck Tales - African Mines(specially this) and Himalaya
Teenage Mutant Ninja Turtles 3 - Stage 4(city) Stage 7-1 (Elevator) and 7-2(Building)
Rockin Kats - All the music in this games are Jazz and Blues.
Akumajou Special Boku Drakula Kun - The SD Castlevania. Stage 2(CLouds) have a perfect music for jazz, and one of my favorites konami works.
Chip N Dale 1 - Too many jazz and Blues here, but i think the best are the music in Zone B, F, G, and Last Stage.
