zipped 2Gb roms are not being recognised, the CRC is correct but the size is showing up as -2147483648
bigger roms are not working either, e.g. a 3Gb rom is showing up as 0 length
unzipped the roms are recognised correctly.
Also found when processing a few hundred 7zipped files that RC gets upset and says "error 8007000e: Not enough storage is available to complete this operation". Using 10 threads on Win7 64, 4Gb RAM. Seems it runs OK for a while then suddenly starts guzzling RAM. All the archives unpack just fine when I use the commandline. When this happens RC concludes that the files are bad and deletes them (if fix preferences are set that way). RC does not appear to release the memory when it has finished either.
