This is still a very fast CPU. I actually don't even own a computer with a CPU this fast.

Mame strives for accuracy, but in actuality it's far from it
It is my great regret that we live in an age that is proud of machines that think and suspicious of people who try to.

It is among the most accurate software emulators and the whole community owes a lot to the work that went into Mame. E.g. when everybody was fine with decrypted cps2 roms, people from Mame implemented the proper encrypted roms, when everybody was fine with the wrong enemy behavior in Bubble Bobble Mame corrected it. The list goes on.

Like the Linux kernel, MAME rejects almost all patches that come from outside their small group. MAME has grown so monolithic that patching the sound to work in one game will break behavior in 50 others. MAME merging with MESS made things 10x worse. Fixing accuracy in old games can turn into a major project.

I totally disagree. I've even got code in MAME. In fact, it spurred further improvements from others which was also accepted.

If your code doesn't make sense then it'll probably be rejected. If not, anyone can submit. Not sure where you got that idea from.

They've rejected my fixes in the past. Afraid that fixing something axiomatic might break a game (but no tests or proof that breakage occurred).
This was years ago, but it poisoned me on contributing.

To be fair, "if your code doesn't make sense" is going to depend upon the perspective of the person who is reviewing your code, and that can often be skewed :P

This must have been before they were up on Github, I didn't see your username up there in any pull requests or issues, which is very probable, it's such an old project and you've been involved in this scene a long time too :) I was curious to see what happened with that.

You can't generalize MAME though. Each different driver in MAME could be an accurate or not so accurate representation of the game being emulated. And there are certainly tradeoffs. Older and less complex hardware might be emulated in a way that is faster but not particularly accurate. But depending on the behavior of the game there may not be any noticeable impact from doing it that way. But if you did emulate more accurately you may get a huge jump in the requirements of the host system.

Either way, more options for playing and preserving these old games is always a good thing.

I'm certainly looking forward to seeing how this Saturn development goes.

I second that, especially since most of the talk is clueless. Go learn MAME first and then, if you have concern, talk about it on MAMEdev or just fork it and talk about your fork in your fork forum.

This is a topic about the Saturn and a core development of it.

I see absolutely no reason to be skeptical. This guy has been responsible for some of the MiSTer's best cores.

Not sure what you mean by"the dev's fpga", maybe you could elaborate. Do you mean that you don't see the de10-nano in the shot, or do you mean you don't see the OSD?

Core development for the MiSTer does not require the core to be integrated into the framework prior to development beginning. Core development also doesn't have to begin on the de10-nano (PS1 core is being developed currently on a xilinx arty7 a100t board, because ultraembedded is used to it and xilinx's toolchain, and the team will figure out porting to the mister later).

Oh you're right. Either way, I think it's useful that people recognize that FPGA core development doesn't necessarily require the MiSTer framework at the beginning. :P

At 1:47 you can see the Mister HUD. Though I don't know why you are doubting the guy who oversees the Mister project itself.

just for the record, I wasn't doubting him. I was responding to someone who was doubting him. And srg320 doesn't oversee the mister project, sorgelig does. Different people :P

srg320 did the SNES core among many other awesome contributions.

I see no reason to be skeptical either. As far as the Mister menu, srg320 mentions in the comments that it is not the Mister menu, but just a placeholder menu.

I probably missed the menu part that's my bad! :oops:

Like i said excuse my skepticism, i come from the time where said they were emulating a lot of stuff when in fact there was nothing untill a lot later.
I've read in another thread where it said the developer Sergey Dvodnenko is a well respected developer so in that matter i've jumped the gun to express my doubts.

Anyway, i am really excited and curious on how well this core will turn out and will keep an eye on this one.
So many good games on the good ol' Saturn!

Could be nice box to be reworked for the Mister once the Saturn core will be there (I really cross my fingers that this happens a day).

It seems that a non official case is already on the go

This is a temporary menu for development.

The wording of the question is pretty ambiguous, and mixes up MiSTer/non-MiSTer with development/release distinctions. I'm sure srg320 just meant that the structure/definition of the menu will change radically before release, not that it's some non-MiSTer menu mechanism.

Not sure what all the apparent mystique and speculation is about.

In order to test multiple things in a single build (because builds can take a half hour), developers will make many changes to menu options during development. So it most certainly won't be the official menu until days before release. But the OSD popup was based on the framework.

Also, for purposes of speeding up builds, some developers also use modified frameworks - Jotego routinely builds without HDMI support (during development periods) because the HDMI scaler accounts for about 10 minutes of build time.

And I'm not even sure how the other question is relevant - related to which dev board in being used...
