i do have a question how do you know the crcs are right if you need to repair them they may be corrupted?
The two I listed are the ones that came up as GOOD against the older RomIdent program. So those are the two I want to match to see if I can find that particular set.
5 sets checked all had same crcs
1c = ofefba
1d = oc9ba9
Not sure how you got those CRC's either..... are you checking CRC32 ?
Yours don't match anything I've seen yet.
ROM files I just dumped from real chips with CRC according to RomIdent -
============================
1a.bin:[E2902B4E] Not Found!
============================
1b.bin:[715A1A80] Not Found!
============================
1c.bin: (1/1) [6AE01102]
- 1C : VS. Exite Bike
============================
1d.bin: (1/1) [F58A392E]
- 1D : VS. Exite Bike
============================
2a.bin:[D8A79A84] Not Found!
============================
2b.bin: (1/1) [80BE1F50]
- 2B : VS. Exite Bike
ROM files available in MAME files (not including Japan version) -
mds-eb4.1a 8192 b9ab7110
mds-eb4.1b 8192 4c0c2098
mds-eb4.1c 8192 89baae91
mds-eb4.1d 8192 7e54df1d
mds-eb4.2a 8192 a9b49a05
mds-eb4.2b 8192 80be1f50
did you check the jap set might have that crc
I did check and they don't match anything I have either.
I started out by just dumping this whole set to see which ones were bad. Three came up good in the old RomIdent program, so I went with those and starting looking in MAME....that's when I found only one file matched between what I dumped and what MAME has.
When I run these files I have against the old RomIdent program they get recognized. When I run them against MAME's romident they are not recognized.
(except for the one 2b file that matches both)
So I've been digging to find a set that RomIdent apparently had in their database.
Now whether it was a good set..... I don't know. But I'm looking anyways.
