Romcenter

I checked my mame 0.273 ROMs folder with Romcenter 4.1.1 and it showed: atarisy1.zip - Rom needs fix, kinst and kinst2 folders - Rom needs fix, nss.zip Rom needs fix, 6331.sound-u8 Ok (bad dump)

How do I fix this?
All other files are green Ok

Hi
Please have a look to the wiki page https://wiki.romcenter.com/wiki/doku.ph ... start:menu
Yellow roms are fixable by selecting them and clicking the 'fix' button.
Bad dump means there is no good dump available and you must stick with it until a new one appears.
