Title: Problem on CRC of darkhors
Post by: emulajavi on 03 January 2010, 00:53

Hi,

i have got a problem on eeprom rom on darkhors
Dark Horse (bootleg of Jockey Club II) [folder: darkhors - parent: jclub2 - size: 6mb]

clrmame pro says its  missing
i have eeprom with crc:
45314fdb

and it says
missing rom: eeprom [size: 128] [CRC32: 1f434f66] [SHA1: e1bee11d83fb72aed9c312bdc794d8b9a6645534]

i cant find one with the correct crc

is it a problem of the dat? of clrmame? mine?
i made the dad with clrmamepro pointing to mameui32 version 136

thank you!!

Well, it's your problem ;) MAME's database gives the hashvalues, so assume they are correct (however there were rare cases in the past where crc32 values were wrong but fixed in a later version).

So, you need to find the correct file.

Sorry for the late reply by the way...end of year holiday.

just for your information: mame is right, clrmamepro is right, the file exists, you need to find it. MAME .136 added a lot of eeproms but they do all exist out there.

Hi Roman,

thank you

so i asume that this eeprom was changed from 135 to 136 right?? size is 128??

i think i have found it!
only one question: could someone who didn't find it have created a file "eeprom" with the correct CRC, Size and Hash, with nothing in it, only to have clrmamepro saying he has the complete set?


thank you, happy new year!

Not really. While it's rather easy today to fake a rom to match the size and crc32, it's nearly impossible to fake it so sha1 and crc32 and size matches.....or let's say, it's not worth the trouble to try so.
