I am no expert here, but this sounds way too much GB, for a a PAL format as maximum resolution. Any lossless or uncompressed codec would produce much less than 90GB for 30minutes.
Uncompressed 13.5 MHz sampling, 8bit
720x480 = 345,600 pixels x 3bytes (YUV) = 1.037 MB / frame
1.037 x 30frames x 60sec x 60 min = ~112 GB / hr. for 4:4:4
4:4:4 sampling = ~112 GB / hour (uncompressed)
For 10bit multiply x 1.25 = ~140 GB / hour (uncompressed)
Also FLAC is just a audio codec AFAIK, but it is true that this codec compress audio with a 2:1 ratio.
One hour audio is about 300MB, so that is not the problem here.
How MAME will handle images with such a size, will be interesting. It sounds like pure madness to me, that a user should keep "master"-files with these sizes. A full Laserdisk collection would easily exceed multiple TB.
