Is there a game for SMS with multitap? I could find list of 4 players games but none of them to play simultaneously for 4 ppl.
I found this on the Mister FPGA forum. I would have thought that either gauntlet or bomber man would be in the list. https://misterfpga.org/viewtopic.php?t=2673 Sega Master system 4 player games Golfamania Great Golf Olympic Gold: Barcelona '92 Parlour Games PGA Tour Golf R.C.

I think cram dots were already always active, now that you have the option to turn off with it off the samurai shodown is without the graphical problems. I'll leave it on, because I want 1:1
I just wanted to say thanks for porting this and thanks for giving us the sneak peak!
Hello, will this new Mega Drive core support Save States in the near future?
Hard to say. The code of MD is netlist which is more harder to adopt for save states.
I noticed that Hellfire (any region) has slowed down music. This is accurate to a model 2 MD, but the older Genesis core has an fmbusy quirk to make it run the music at full speed like a model 1 MD. Would be nice to see that in this core too, if it isn’t too much trouble
Same as Daisenpuu / Twin Hawk? The Analogue Mega SG has this option, but there is no option in the MiSTer core currently that I'm aware of.

There is similar "glitches" happen in Sonic 2 in dual player, bottom player has glitches on top. There is no such glitches on Genesis core. Why? That's because Genesis core's VDP and Arbiter are written based on known functionality like soft-emulators while real hardware had some limits giving such artifacts (similar to CRAM access collision producing visible dots). So, yes, Sonic 2 glitches happen exactly as on real hardware.

It’s actually like that on a real Mega Drive from what I can tell, I found this stream VOD from 11 months ago that shows the exact same glitches.
Shining in the Darkness, top right corner after naming your character there are graphical glitches, a scanline of pixels randomly flickering. https://www.youtube.com/watch?v=YDnbgw8lWx0 EDIT: This occurs on original hardware confirmed, so disregard.
Don’t know if it works on real Mega Drive, but the Korean game Superboy for the SMS only have sound but no image
i cannot test on real HW but according to info i found it's bootleg MSX game originally, so it most likely uses non-SMS video mode and thus most likely cannot work on original MD as well.
On the SMS mode, Phantasy Star, the song for the introduction when you first start has some odd ringing that is not present in the SMS core. I don't have a power base converter to compare to see if this happens on original Genesis/Mega Drive hardware however... EDIT: It seems that most SMS games have this ringing on the PSG now.
i see. Need to revise filtering. Set audio filter to "no filter". Ringing will disappear
You can use mgl file if you want to use MegaDrive core with Genesis name (and Genesis core for games). Att: it will share settings with Genesis core!
Make sure you have only one MegaDrive rbf, or mgl may pick the older version.
Thank you!! This version works perfectly on my CRTs via directvideo! Very much appreciated :)
something wrong with TMSS. I will check. Please disable TMSS for now.
TMSS It's the charm of the Mega drive :)
Thanks Alexey, the Demons of Asteborg music sounds great with this version
This core is great! Thank you for your great work! Love the SMS part too! Sorry for the noob question, but is it possible to point the rom folder to “genesis” instead the folder “MegaDrive”? I use a HDD (USB 0 - exfat) for games and tried to create a shortcut/link using winSPC but I couldn’t get it to work.
open linux console and enter MegaDrive folder then type there: ln -s ../Genesis Genesis ln -s ../SMS SMS It will create Genesis and SMS links inside MegaDrive folder.
