buckrgrs fails to load -- CRC has changed out from under me

[gorgatron1]

I recently upgraded to the latest vpinmame (3.6.0-998-a77c2d2) and noticed a couple of games that used to work no longer work. For example Buck Rogers (buckrgrs.zip). I get a message saying that the game failed to initiaize, so I ran the tester in Setup64 and sure enough there is a file missing: A1752CF.bin

It looks like it is probably down to this change from about 4 months ago:

- GTS1_2_ROMSTART(name, "u5_cf.bin", CRC(e0d4b405) SHA1(17aadd79c0dcbb336aadd5d203bc6ca866492345), \
-                      "u4_ce.bin", CRC(4cd312dd) SHA1(31245daa9972ef8652caee69986585bb8239e86e))

+ GTS1_2_ROMSTART(name, "A1752CF.bin", CRC(614a3bd9) SHA1(febca18fb6f96037ca82e515dd161dfcb0e4c776), \
+                      "A1753CE.bin", CRC(4cd312dd) SHA1(31245daa9972ef8652caee69986585bb8239e86e))

My filenames match the u5_cf.bin but I think it is actually matching on the CRC and now my u5 doesn't have the right CRC.

What is the proper way to handle this? Is there a way to have it accept the old files (that I have)? Or do I need to find replacements (which I have been unable to do so far)? Is there a way to know all the files that are missing?

Thanks!

Sooo, I think I figured this out -- please let me know if this is right:

• I remove the u5/u4 files from the buckrgrs.zip
• I create a new gts1.zip using files with the new crc/sha1 (which I found by searching by crc)
• vpinmame now finds the files in gts1.zip
• I repeat the first step (removing the u5/u4 files) from every zip that contains those

The first and last steps should not be necessary, as long as you have the correct (updated) gts1.zip.

(unless you want to clean up unnecessary files)
