Hi. I upload here a not accepted version of Wild Fang by MAME team. A year ago around this date, I dumped a board that came to my hands, and sent the binaries for them to be studied.

These binaries were classifed as a hack, not sure why, they didn't gave me any reason. They only saw that "too much info inside was different", but not what the info or the gameplay was changed.

So here is for you all. Check it by yourselves

Edit: I see this was submitted along with PCB pics etc. so great work.

From the commits i can see people thought it was very different from the original release.
Even if the year was hacked then it would have been a different revision.

However, it turned out to be a 2-byte different version.
Not sure where the confusion came from that it was largely different revision.

Thanks for releasing this for all to check out if indeed it's just two bytes different :)

This is another 1991 version, not the one mentioned before.

Mine has a lot of different changed code
 
Even if they thought it was a hack surely it should have been added to mame? half the roms in mame are hacks / bootlegs.

No idea. They said that the Mitsubishi stickers should say it's a non licensed hack. I have waited a year for free it for avoiding problems with MAME team, so I don't want any discussions with them

A set was submitted to Mame, added, but then later removed as stated a two-byte hack.
Nem's screenshot shows a bigger difference than just two bytes, and the gfx roms are really different.

@Tailsnic Retroworks : To get around the initial confusion, you had two sets? Can you also post the set that was later removed so we can see if it's actually a two-byte different version please?
 
I pinged Haze on Twitter and he said only difference was the date, so maybe there is confusion on which set was submitted.

I linked him to this thread so he's welcome to chime in if he's a member.

The uploaded here is the one discarded. The MAME team said that was so much common to see sets with the 2 bytes of year changed, but mine is also more than that
 
Guy's, according to Haze, the reason is as follows:

WildFang_1991_3S.BIN 1.3s IDENTICAL
WildFang_1991_5S.bin 2.5s 99.998474%

the only change is 89 -> 91, operators sometimes did this to make the games they had look newer, it's not likely to be official and really isn't interesting

the problem is people are comparing it to the 'wildfang' parent set, it's a date hack of the 'wildfangs' Japan set.

Again, this is not from me, I asked the MAME dev and that's his answer. He's been really helpful before and I don't doubt his knowledge on it. I'm just posting so we have all the info.

@Tailsnic Retroworks thank you for both submitting it to MAME and for posting here. I appreciate it!

So, it is really a "1991" byte hack and the rest of CPU info is re-arranged. Well, that's a pity, xD
