Missing MAME ROMs

There are a few MAME ROMs that I am missing, one of which was from several updates ago, and for the death of me, I can't find them anywhere. Please help me. They are...

sqi_mips:irix_5_2_b

msx2_cart:megascsi2

msx2_cart:megascsi4

rm380zhrg

Again, please help me with getting them. Thank you.

 msx2_cart:megascsi2 and msx2_cart:megascsi4 are still coming up missing, but glad the other two are working, specially the first one, been driving me nuts for awhile with why I couldn't find it. Thank you for this!!!

They are all the same .....hmmmmm....I have not checked my SLthe 0.264 relase yet ..........

OK, so just renamed them adding a 2 and a 4 at the end and it worked. Thank you!!!

After auditing my roms, it seems that I'm missing 1 after the update.

The download section doesn't seem to have this file nor does the Mega update.

Can anyone please help?

Thanks
