The SPC2 format was designed by Kevin Horton. marshallh and CaitSith2 created this conversion program. https://forums.nesdev.org/viewtopic.php?t=8558
SPC2 format specification: http://blog.kevtris.org/blogfiles/spc2_file_specification_v1.txt
Usage: spc_pack.exe <DIRECTORY_OF_SPC_FILES>
Creates an .sp2 SPC2 file in that directory's parent directory, with the same name as the SPC directory.
SPC2 files can be played on Analogue Super Nt, running JB firmware.
