Like .Rar, .7z, or .Zip?
The reason I ask is because I only have a 2GB MicroSD Card and space will become an issue. Especially when 500MB roms like Pokemon B2 could easily become 250MB if compressed.
My card is the R4i Gold 3DS Revolution from nds-card.com btw, incase it matters.

How efficient is TokyoTrim? Also, would it be possible to later reverse the trim (without the original file)?

ROMs doesn't compress well in zip/rar anyway, you will have better file size by removing unused trailing bytes (trimming all the 0 after the actual game's data size).
if you used zip/rar on your flashcard, you would need to extract it every time before launching the game as the DS doesn't have a background processor to do it while playing, and you would end twice the size of the game on your SD card.

Flashcarts aren't capable of running compressed games. You can trim the ROM files though.

it's possible to remove 00's but not the other way around, you'd need to write somewhere where those 00's belong..

Anyone know if Lameboy can run GBC games from in zip folders?
I have my GB/GBC romset with each individual roms in their own zip folders...
