It’s pretty much complete. I’d appreciate it if a few people could try it out and report any problems. Especially those who had problems with the Mario Bros core.

Gave it a try! Looks good, I saw some random letters on the screen. I don't remember if that's normal or not.
Thanks again for your efforts!

Thank you. Looks like it still needs some work then.

Yup, I'd say it's about 95-97% complete. Well done!

Looks like coining is a bit difficult to validate.Else it seems to run quite fine.
Thank you !

Thank you @gaz68 ! Some issue on my side to add coin not working everytime.

Having issues with Mario Bros here as well - disappearing sprites (mario's head) and other graphical errors. Seems like the game runs fine briefly sometimes and then some havoc starts to happen.

Mario Bros works fine for many but for others its' doing some random stuff. It still needs some work.

Donkey Kong 3 expects a short pulse for the coin input. If you do a quick press and release it will work every time. I think I can 'fix' it though by generating a short pulse after the button is pressed.

Thank for the change of add coins in DK3. It is working great on my side !

great improvement in coining for dk3
works every time now.

Thank you : the game is really fun to play !

on donkey kong 3, it looks like there are some random characters appearing sometimes on various part of the screen.
I am not sure that they should exists.

I have the reset issue too, tried copying files directly on microSD(no ftp), changing microSD, removing Power Switch, started without SDRAM module. Only three times the game started, totally casually, then the reset issue has back.

Not sure why no responses here, but I'm having similar reset issues mid-game with DK3 as I am having with MB. Basically, plays fine for a level or so then suddenly returns to the attract screen. My MiSTer doesn't have any DRAM installed, currently, but I didn't think it needed any for these cores.?

I uploaded Mario Bros build with improved stability on this thread.
I'd be happy if anyone facing random issues could test it
