Genesis / Megadrive core ported to MiST

[vebxenon]

Well, after formatting and defrag the card, now I'm able to change the game without resetting the board. Hope we'll see new updates for this great core .

I've done a thread on Twitter with pics of 30 Mega Drive working games:

All the shots done directly to the MiST monitor using my mobile's camera (Lumia 950).

And all the games work perfectly ?

These 30 games are perfectly playable athough there are some minor glitches.

I've found some time to play with the Megadrive MIST core recently, and have managed to reduce the sprite flickering problems significantly.
Updated binaries are here: http://retroramblings.net/?p=1189
and source here: https://github.com/robinsonb5/fpgagen
It's not a total fix - there's still some flickering in busy scenes, but it's much improved from what it was. Please test - I've only tested on my very early MIST board - hopefully it will be stable on newer boards too.

Nice one! Will try when I get a chance.

Great to have you back!

Hi!

Thanks for your work!

Still not perfect, but let me show you the progress on a pair of 'before-after' pictures:

[DanyPPC]

Thank you very much for this great update.

I will test it on both Chameleon and MiST platform

I'm testing it. Thanks very very much!

Just when I thought the MiST was dead, you came around with an update to the Genesis core. Thank you. This is a nice improvement.

Just a question, Megadrive pad support will be added?

[DanyPPC]

I think it's not possibile (pins are different, to switch 5 and 7 for the power), unless you make an adapter.

It's more simple to map 3 and 6 button megadrive pads on a standard CD32 joypad.
But in this case better use a commercial supernes or megadrive USB style pads.

I've ordered a Mega Drive style USB pad

[vebxenon]

Now I have 70 playable games in my SD . Still testing games . I think a region selector could be great for some games . Great improvement!

[DanyPPC]

Hope in a future audio improvements too

Yes, some games now are graphically playable, but sound is bad . Also, it could be possible to adapt this core to the general OSD?

Possible, yes - but not a high priority for me because I want it to remain buildable for Chameleon64 and DE2 as well as MIST.

Ok . Well, I've tested a lot of games and now I have 90 in my SD. That's great!

I've bought a Mega Drive like USB pad, but button layout is weird, A, B, Y and X to start. Can I remap the buttons?

Ah, remapping would be an excellent idea even with a 'correct' pad to be honest...

If all else fails though I guess rewiring the pad itself is not such a big deal, their construction is very simple.

[DanyPPC]

But not in the case of a USB pad.
Better an option or a ini file to configure for the core.

My opinion

[Gryzor]

Ah yes, you're right, I was thinking old-school.

Not impossible depending on the construction (in some case it's actually easier, in my MAME cab I used the boards from some cheap USB pads and just re-arranged the wires where they were inserted into the board), but if the pads are surface-mounted indeed it's a PITA.

Yes .

Here's the official tutorial how to remap USB game controllers on MiST:

I tried it earlier with a Thrustmaster T.Flight Stick X joy, and works great!

, I'll try it at home.

Ooh nice!
