Home Page Forums MAME MAME The SNES WIP topic

Shit, i forgot about the Cx4: I have a megamanx2 cart for that as well.

As for money: we may want to have one person sort of 'consolidate' any donations together, then send that to dr. decapsulator at the end. Mr. Do on the mameworld forums does something similar for buying bezels, and smittdog does something similar as 'the dumping union' for buying rare pcbs for mame.
Money should if sent via paypal be sent as gifts since that way paypal takes much less of a cut of it.
I nominate byuu to accept donations for now.

We should aim to do a dsp-1b first imho, so I'll see if I can find a cheap dsp-1b cart on ebay or find someone who's willing to donate one to the cause. (I'm working on this)
Edit: Done. Just got a ballz 3d cart from ebay for $4 including shipping.

As for upd77c20/77c25 code to work on to get the core working: Sega's air rescue arcade machine used a upd77P25 (eprom version) with the protection bit NOT set, allowing it to be dumped, which it was; the chip is used for intermachine communication only afaik, but it should be valid code. Also I have the upd77P20 code from that prose 2020 speech synth which if shifted around a bit to make the bits line up should also run on a 77c25 (the 77c25 is backwards compatible with 77c20 code with appropriate column shifting of the roms, that's why the ram increment ignores the highest address bit on the 77c25)

And before I forget:
UPD7720 = nmos mask version
UPD77C20 = cmos mask version (I have one of these on the Infovox speech synth card rachael sent me, not dumped yet but is unprotected)
UPD77P20 = nmos eprom version (I have one of these on the prose 2020 speech synth, dumped)

UPD77C25 = cmos mask version, has protection bit. DSP-X are these, with protection bit set.
UPD77P25 = ?cmos? eprom version, has protection bit. Sega air rescue uses one of these, with the protection bit clear, which was dumped.

LN

I do not remember exactly in what MAME drivers, but sometimes emulation of the real hardware has proven to be faster than the simulation.

The later Namco games. VivaNonno's black box simulation of the sequencer running on the M37702 and C352 synth chip ended up being significantly slower than actual emulation of the chips.

Actually this isn't a bug. Setting the frameskip to "automatic" fixes the problem.

Did I've already said that bsnes is right and photo subject should be centered since I've tested it on real HW?

I'll try to act surprised that this is the bug that bothers Kale the most ;-)

On the DSP-1b decappin' - I am in for $50. I like the pool method. Send to byuu now or should we wait for people to commit the rest?

What game is that?

I've posted about the fundraiser on my front page, and I have three offers. One sent $50 so far. Another was for $10 and the last one didn't say.

Once I have $200, I'll throw in some money myself as a tip per LN and send it over, along with the transaction ID# and a screenshot and all that.

I suppose we can coordinate when and where to send stuff once Ballz 3D arrives and the money is ready.

ht1848, thanks for your interest. You can e-mail me at setsunakun0 at hotmail (please don't send money to my hotmail address! I won't be able to retrieve it) and I'll give you the PayPal address (don't want people sending me money out of the blue), or post on my forum. Either way


Bishoujo Janshi Suchie-Pai. I only know that because I fixed an issue with the PPU counters that was affecting it :P

Well some graphics problemas in SMW2 - yoshi's island:



And the DDR-4 Top Gear now Brokes after reache the planets screen (just before the race begins)...
