#2331: mythgame computing bad crc values, all systems, all bad
 Reporter:  njustn at gmail.com  |       Owner:  greg   
     Type:  defect            |      Status:  new    
 Priority:  minor             |   Milestone:  unknown
Component:  mythgame          |     Version:         
 Severity:  medium            |  
 I'm running current SVN dev mythtv and mythgame, and just switched to that
 from V 0.19, both have calculated bad crc values for every rom I have.

 Example, snes rom Donkey Kong Country (V1.0)(U)[!].zip

 mythgame crc: 4ad0bf54

 zsnes crc   : c946dca0

 romdb crc   : c946dca0

 As far as I have been able to determine, zsnes gets the crc right, i.e.
 matches romdb, in pretty much every case.

 My system is a dual 1800+ athlon MP, 1.5GB ram, running gentoo, my
 filesystem is reiserfs.

 Also tested, with identical results, on an Intel Pentium4 3GHZ laptop, 1GB
 ram running gentoo, same files, on ext3.

 The snes roms are zipped, but the sega ones are not and they show the same

 Any thoughts why this might be happening? What code is used to generate
 the CRCs that go into romdb, can I test it to see if it comes up with the
 same values as mythgame is giving on my computer?

 Anyway, sorry to bug you guys here, but as far as I can tell, nobody else
 seems to be having this problem, so this is kind-of a last resort
