[ukvac] Help Mr Do
Hi there

Can anybody tell me what roms I need to burn from which Mame files???

I have a Bootleg Mr.do which I sort of fixing for a mate... this board has
the amp on it.....

However with being a bootleg board there is no pal.... all the eproms match
the original except number 4 which either matched MR lu or Mr du.....
however this does not correct the problem of the missing pal..

I no the board is ok as if I try a pal the game is then fine... well that
part of it anyway...

Anybody know???? I'm sure this was talked about on here before...

But Yahoo seems to be messing me around again.

Regards

Daz

RE: [ukvac] Help Mr Do
Ahh, having just re-read this post (or rather actually read to the end!) I know
this one!!

If the pal is the same IC that I think it is then there is a rom which just
needs a single byte changing. Myself and Juno did it to one of my Mr Do boards
to fix a problem with the game locking up which was caused by the IC failing
when hot (it was a genuine Taito board, not a bootleg). So we changed the byte
in the rom and removed the IC - worked fine from then on.

So what you really needed was for me to have dumped that rom before I sold that
board - which in typical fashion I never did (and was meant to for Juno -
oops!).

Juno, you reading this? If so, you have the answer :O)

If you look at the mame driver code it tells you about it, and says that it's in
memory region "REGION_CPU1", but that only narrows it down to one of four
roms...

Let me just correct myself there before anyone else does (cheers Lee!)...

IIRC the board was not a genuine Taito as it is in dispute whether such a thing
ever existed at all (all known ones have no Taito marking whatsoever which is
NOT like Taito at all). But in fact the fairly common bootleg version with
"Licensed by Taito" (or whatever) on the title screen.

Doesn't really help though as that one (at least mine anyway) had the PAL in
question.

Does this just make it a "good" bootleg, or would that throw some weight behind
the conspiracy theory that is the Taito MrDo! (the fact it used the PAL that
is)?

The board I have with the Taito license on the title screen is an
original Universal PCB...

...The board I have with the Taito license on the title screen has the on-board audio amp (big deal), lack of Taito markings or little white sticker (as mentioned before) BUT the printed text on the board marking out the various ICs is identical in style, colour and size to my genuine Taito Dark Mist PCB. Coincidence?
