Hi, all.

I have one question.

Recently, I'd found out my MegaFlashROM SCC+ SD has the files such as opf, opfx and opfxsd in the drive "A". When I make my own MegaFlashRom cartridge, I used opf. However, when I visited to the original shop, opf and opfx are already obsolete and they recommend to use the opfxsd.

What's the differences between those files? Any information of those files?

Simple as that:
You got a MFRwith additional memory mapper and SD slot? Use the OPFXSD app to flash your card.
The OPF is a early version, made for MFR w/out this features. And, you guessed right, OPFX uses cartridges with SCC build in. Why the still remaining on your cart? I´m happy about, so I can use it for all my flashcards, if they bother you, than delete, kill, erase or wipe them out.

Original MegaFlashROM SCC with 512kB flash: OPF
Improved MegaFlashROM SCC+ (has 1MB flash): OPFX
Extended MegaFLashROM SCC+ SD (8MB flash, 1 or 2 SD cart slots, optional 512kB RAM): OPFXSD

Only the latter is still being sold, that's why the other ones are marked as obsolete, I guess.
