Looks like the test mode pin is connected to the upd78p214 along with the serial port(?). Would be neat to make the networking work.

only unemulated feature is the dipswtch that I'm not sure what is supposed to change (maybe the game time? game score?)...

That's a very expansive cart :p

yeah, it seems the board had some sort of serial connection. its emulation is probably beyond my current set of skills, though (my frustration with MegaDrive serial EEPROMs exposed that I clearly suck at understanding serial comms from the running code), so if you want to take a look, the relevant slot device is at src/mess/machine/sns_event.c

crazyc: to quote byuu from this reddit, "there was no score uploading from the SNES to another machine, there was no networked play".
What did it do? "That connector was only used to feed status register bits. One of the bits activated a mode where each player got to enter their name, and then the system would wait. Once all players had their names in, the host could clear that bit and the game would start playing for everyone at the same instant. It ensures that everyone finishes at the same moment."

Did any of the other currently dumped "championship cartridges" do that kind of stuff, besides NWC? In that case, perhaps there's still some chips awaiting to be dumped in those?

We'd probably need a dump of the mcu prom ( which looks like it'd be possible) because as Logan says, I don't actually know what it does or if it's even a serial port.

I'm going to commit very soon some uber preliminary SA-1 code
For the moment there is not much more than ROM & RAM mapping (maybe with mistakes too), still it is enough to reach a few title screens which were impossible to get until now in MESS smile

one of the shogi games gets even in-game then it dies (probably when the SA-1 is used for the opponent AI)

OTOH, the most interesting games don't offer much to see at the moment: Kirby Super Star, Kirby's Dream Land 3 and Jikkyou Oshaberi Parodius sits to a black screen and the following is all that SMRPG has to offer

This is a bit of a necro-post, but I just now noticed it. Seeing as the Super Smash Brothers series has always been Nintendo's way of pillaging their historical archives, I wonder if they got the idea for the Home Run Derby mode in SSB:M and SSB:B from this.

about home run challenge, I think there were various 16bit games offering such option, not sure where Nintendo got its inspiration for the SSB game mode...

anyway, with some further change Jikkyou Parodius now boots up and gets very close to gameplay

too bad it fails when things would become fun

I find it surprising how far SA-1 can go without interrupts and DMA wink

Not sure if I'll be able to improve it further: my attempt to hook up NMI & IRQ lead to a bunch of regressions (I guess I failed to properly notify back the acknowledgement...)
We will see...

Guys help!! I can't get any "software" to show in the picker list in SNES. All other MESS "systems" work ok except snes. My games images/roms are in .smc format, and is a set from about a year ago. Could that be the problem? Please help frown


The developers of MESS have my sincere gratitude. Thank you guys.
