What's your set up? You planning to produce music from like say just a laptop or you have your own rig set up with midi keyboard and stuff?
If you are on the go most of the time and don't plan on making extremely complex pieces you can go with boscaceoil or use a full music producing software otherwise. I use FL Studios
If you have an iPhone you are in luck because I just bought a software that you would love. It's a synth called SquareSynth2 and I also have the original in my iPad. The original is more simple but also more limited. Apparently you can use SquareSynth2 with Garageband by using Audio Unit V3 or additional audio bus software for rerouting your sound to garageband, but the most convinient solution is to connect your phone to PC and record everything as a sound clips inside a DAW program.
From where we get to the next topic. You can create chiptune songs inside the Square Synth and export them. This is the easiest way to do and simple enough for anyone. However when you get to the next level, you need to get DAW software for your PC or MAC. I personally use FL Studio, but there are also free alternatives like Reaper which can be evaluated for a certain time. I also would use windows as a platform because there are lots of great Vst plugins made for it that can be acquired and used freely.
"Does anyone know the name of Of that program that makes actual snes music"
If there is one, I'm very interested. Unfortunately only possible way to actually produce "actual" snes music is by the hardware itself. Everything else is an emulated solution which tries to mimic the sounds of the Snes. Also nes and snes has a modular chip which can be programmed and thus, all the games might have a little bit different sounds for their music. They can also have samples, which means that they have unique sound clips recorded during the preproduction, thus they are copyrighted and cannot be used.
They are most convinient way to create music and try different solutions and era's for your midi track. Be aware that you need to be sure which soundfonts can be used commercially, because they might include these copyrighted samples.
QUITE a bit late, but if you're still looking for programs to use:
SNESMod (an IT to SPC converter)
XMSNES (an XM to SPC converter) -you'll have to search for this one, or compile it- IT2AMK (IT to SPC and MML, for AddMusicK, converter) chipsynth SFC (by Plogue, brand new VST plugin for DAW's to create authentic SNES music, but no export to SPC) *non-free* Super Audio Cart (by ImpactSoundworks, gives you SNES-like samples with the SNES Verb plugin they created) *non-free* SNES Tracker (by bazzinotti, newly released with still very early builds, it's a true SNES Tracker program that outputs to WAV and SPC)
If you don't want to jump through major hoops to get authentic music, go with Super Audio Cart. If you want authenticity and are not worried about SPC output, I HIGHLY recommend chipsynth SFC. For the nitty gritty, get your hands dirty and learn some tools deal, then go with IT2AMK, SNESMod or even the new SNES Tracker (if you don't mind using music tracking software). I prefer IT2AMK due to having ASDR envelopes instead of pure gain like XMSNES and SNESMod does (which creates a lot of popping).
Highest recommendation is chipsynth SFC, however. Once you learn how to use it, and it's on sale right now for chump change, you'll be able to bust out authentic 8-channel limited SNES tunes with true SNES echo effects. If you need guides on how to use it, check out tssf (Mathew Valente's) YT channel for a series on how to use it.
The second draft of my script is almost done, and I don't think I'm going to write a third draft. I'll make changes to dialogue here and there, but I'm happy with the series of events the way they are.
Just found an obviously custom effect (i.e. edited by me) in my resources>sounds folder called "rip jaw off". Dear Lord what is wrong with me as a person that at some point I needed a sound *specifically* for THAT??
