MAME issue: Dancing Stage Euro Mix 2 (G*C23 VER. EAA) doesn't work

[mamicilla]

;A; hello guys, I'm desperate!
I've been trying so much to make this dammit rom run on MAME 0.142 but there's no way! I've got the chd file, I've got the.u1 and .u6 files (and mame tells me they need redump) and also it tells me I'm missing some other files "
I feel so helpless ;A; I'm a girl and I'm not that used to programming things on the computer.. Please treat me well!

I'll just copy the errors here, k? ;A;

700a01.22g NOT FOUND
gkc23ea.u1 ROM NEEDS REDUMP
gkc23ea.u6 ROM NEEDS REDUMP
ERROR: required files are missing, the game cannot be run

Thank you so much in advance :<

700a01.22g is inside the system 573 bios files, search and download "sys573.zip"

You can try to run mame but I doubt it works because it has two bad roms (the emu can freeze, screen glitches, etc):
gkc23ea.u1 ROM NEEDS REDUMP
gkc23ea.u6 ROM NEEDS REDUMP

Wait (months/years) for a redump...
