@mitu I agree, it should, but it doesn't. None of the buttons do anything. It's using the default button mappings that work fine for all my other 32X games, nothing different.

[EDIT] Ah, there was a Picodrive update available, that sorted it.

Yeah, it looks like I assumed the official doc was still the page I needed to check. I was able to find that now (although it was a bit confusing since those are two different things...settings vs controls). However, it's working now.

But now I'm wondering about something. None of the other emulators that use the six-button controllers require me to force the six-button settings in the Retroarch core first (or at least the Sega-based ones). With core remapping, I'm able to get them to cooperate. Would there be any benefit to turning on six-button in the other cores (where core remapping is already working fine)?

Hello All,
I'm dealing today with the same issue but my investigation shows so far that for me it is only related to PAL MD games

I opened a separate threat here with some more research : https://retropie.org.uk/forum/topic/34696/megadrive-50hz-games-with-genesis

The problem that I have if I use 1980 x 1020 @ 50Hz is that the monitor for whatever reason has black borders all around and I experience this on PI4B

I forget which emulator but one of them has a core option for 6 button and 3 button controls. The other just has some of the 6 button games working with 6 buttons and some are stuck on 3 buttons.

@mbrett Do you have a screenshot to show the problem ? Have you tried toggling 'Integer scaling' on/off to see if it makes a difference ?

@quicksilver I have 6 button setup working on both emulators as of now. I found the settings you mentioned in Mortal Kombat II but changing them made no difference. I went over everything on my setup and was stumped. I booted up a fresh image, completely up to date, configured my SNES and Xbox controllers and put on my Sega games only. I made the changes to the respective config files and presto it works. After changing the setting you pointed out that I missed earlier in Mortal Kombat. I don't know why my original setup was not working. It has to be something I modified but I haven't found it. Thanks for you help and if I track it down I'll let you know.

Update: I think I found the problem. When I updated in the morning I did both binary and source, I've never used source before. It wrecked my controller configurations. It had my generic SNES listed as generic and just SNES, and the Xbox controllers were listed as generic Xbox, the original config, and Xbox 360 Pro. Every game I launched listed the two controllers I had connected twice and then worked in piece. Not sure why updating from source would do this as I have updated from binary and it was fine. In the future I will probably unplug all controllers and use the keyboard for updating.

I've fixed this issue, went through the key binds once again and now it works, another problem though so I'll make another thread.

If it also happens on Kega Fusion, it's going to happen on real hardware.

If it's excluve to PicoDrive, try updating the core because there has been some major improvement in 32X emulation (exclusive to the core, not the base code).

Else, you'll have to live with it because there's no other portable open source 32X emulator (until it gets fixed).

@titchgamer Good to hear you were able to solve.
Yes, sometimes things can really get messed up.
Backup is your friend ;-)

@capeman Nope,

I had to manually rewrite it.
It seems swapping the controllers caused it to automatically over write it.

Strange really :s

for me the problem was the cpu/cyclone git either failed on 443 or it was intentionally trying to use tcp-9418 which was blocked by my firewall. I gave it temp any-any-allow rule and it made it through the install.

@moltavia Use the binary install (looks like you tried to install from source) or clear the source directory - not sure why git failed. networking or old source tree left over.

@gizmo98
Thanks a lot, I'll take a look inside that script :-)

@beretta9 Your solution worked for me, thank you very much. Too bad lr-genesis-plus-gx has a far less satisfying performance.

@backstander

Just keep them away from 'Donkey Kong Jr. Math'. An ape in a diaper has no business teaching arithmetic.

For anyone interested, I was able to figure this out,

I was using crt-pi shader, but for whatever reason this causes problems with genesis plus gx. Using crt-pi-vertical shader produces the identical results that I get in other emus using crt-pi shader.

@Pyjamarama short answer: no

@Lyle_JP I'll have you give that a try - I've been using Picodrive since RetroPie 2...

The binaries have been updated.
