Version 1.0 should have a crc of b515dd0d and be 597250416 bytes in size thats 569MB might show as 570MB
Version 1.1 should have a crc of 7af84f63 and be 664806912 bytes in size thats 634MB might show as 635MB
I'm guessing at version 1.1 that you have there
The one we have up is version 1.0, judging from the file size, the crc is mismatched but it is in img format created with clone CD that 9 times out of 10 messes something up nothing bad realy it just puts FF instead of 00 in hex for blank spaces
P.S. you posted in the wrong section, Everything Emulating is for emulating consoles on a computer, that would of been easier as it happens... oh well

not to worry I shall move this for you to Everything Console
P.P.S. do you need a cue file to go with that or not?
Almost forgot about a certain boot CD you can get for chipped PSone consoles, works with all PSX models it was just originally made for the PSone when it came out
Import Player is what I'm thinking of though your not using it to play imports

it has some anti mod chip option on it, I forget the exact term they used as it's been years since I needed/used the disc, but worth a shot for you
You can get Import Player Lite from

Make sure to grab the
Import Player light (U) [NTSC] version
