The Supercard “magic” homebrew patcher is a very simple utility that patches a homebrew .nds/ds.gba/whatever file and creates a .sc.nds file which is guaranteed to work on the Supercard series of flashcarts.
Due to the way the Supercard firmware works users are required to run ds.gba files renamed as .nds. Simple enough since most homebrew is distributed in both forms, however a lot of older stuff only came as .nds meaning an extra stage prepending the ndsloader was required. Over time the extension .sc.nds became adopted for these types of files and the first supercard specific homebrew patcher ( scconv ) was developed.
scmhbp was inspired by this initial patcher ( and dsbuild.exe ) however both older utilities just blindly prepend the ndsloader.bin to your file, even if it would have worked anyway or already had a ndsloader. scmhbp checks if the file needs a ndsloader, removes any extra copies in addition to ensuring the file is a valid nds homebrew file.
Basic usage instructions are included within the zip, however in a nutshell you simply drop your .nds/.ds.gba on scmhbp.exe. On linux ./scmhbp /path/file.nds.
Version 0.2 was uploaded only recently but the only difference the previous version were very small changes needed to add linux support.
