Summary	02579: All Sets in neodrvr.c: neogeo.zip bad crc's and misnamed (or renamed) sfix.sfx
Description	It seems that from mame (i686) .127 to .128 expectations for neogeo.zip have changed, and the file sfix.sfx is now named sfix.sfix. I do not know if this is a typo as far as the filename goes. I also do not know why the checksums have changed. Nowhere on any site have I found a neogeo.zip with a file named sfix.sfix, they all contain a file named sfix.sfx. Here is the output of the command mamepp mslug5 (i simply extracted sfix.sfx to a folder, renamed it to sfix.sfix and then added it back into the neogeo.zip to fix the following missing file error): 000-lo.lo WRONG LENGTH (expected: 00020000 found: 00010000) 000-lo.lo WRONG CHECKSUMS: EXPECTED: CRC(5a86cff2) SHA1(5992277debadeb64d1c1c64b0a92d9293eaf7e4a) FOUND: CRC(e09e253c) SHA1(2b1c719531dac9bb503f22644e6e4236b91e7cfc) sfix.sfix NOT FOUND sm1.sm1 WRONG CHECKSUMS: EXPECTED: CRC(94416d67) SHA1(42f9d7ddd6c0931fd64226a60dc73602b2819dcf) FOUND: CRC(97cf998b) SHA1(977387a7c76ef9b21d0b01fa69830e949a9a9626) 263-m1.bin WRONG LENGTH (expected: 00020000 found: 00010000) 263-m1.bin WRONG CHECKSUMS: EXPECTED: CRC(46ac8228) SHA1(5aeea221050c98e4bb0f16489ce772bf1c80f787) FOUND: CRC(38ffad14) SHA1(03d526a887aad28306400c21abd131b9c301c221) ERROR: required files are missing, the game cannot be run. After adding the renamed sfix.sfix file to the neogeo.zip even though there were CRC checksum errors, mslug5 runs fine (and the cheats now work in .128 YAY). What's the deal with the wrong checksums though?
Steps To Reproduce
Additional Information	Extracting sfix.sfx from neogeo.zip renaming it to sfix.sfix and adding it to the neogeo.zip will allow you to play neogeo games. I have no idea why the CRC's for the files (and the sfix.sfx filename) in neogeo.zip have changed from .127 to .128.
