@Machtroid Thanks for the confirmation. Btw, if you upgrade now (again) the OS packages, there's a new kernel & firmware update (20230509~buster-1) that should fix this and the config.txt change should not be necessary any-more.

I found the answer, and it was the most obvious, of course.
The SMS pause button is configured as the Port 1 Start button in retroarch, so whatever input I bin to Port1 Start does the job. Fortunately this still works if I have the input type as Light Phaser.

I just found out about this while installing retroarch on my tablet, super impressed with it, i really hope this will be included into retropie sometime soon.
Thanks for the instructions of adding it ourselves.

Don't you just hate when you have had a problem for days and you finally ask for help, you happen to figure it out? I guess it's cause at that point you abandoned your train of thought.

Anyways for anyone else trying to get the analog features working for farious SEGA games and rebind them for your flightstick or steering wheel I've made a little chart so you can add the rebinds manually

Find your games keybindings file, as example i'll use Afterburner II on the MegaDrive. which can be found at: "/opt/retropie/configs/megadrive/Genesis Plus GX/"
In my case with filename "After Burner II (USA, Europe).rmp"

Open it in notepad and adjust your keys, here is an example of the default buttons, with the A,B,X,Y buttons added, and the vertical throttle removed.
I've also made a little picture you can use as reference, you'll find that under the code, it has all the numbers you need to use.
That's all, have fun setting up your flightsticks and racewheels on a 16bit console.

#Device ID for XE-1AP: input_libretro_device_p1 = "773" #Start and Select input_player1_btn_select = "2" input_player1_btn_start = "3" #A,B,X,Y = East,South,North,West input_player1_btn_a = "11" input_player1_btn_b = "13" input_player1_btn_x = "10" input_player1_btn_y = "12" #D-Pad is unused so lets add Select and Start to it incase your flightstick doesnt have enough buttons input_player1_btn_up = "-1" input_player1_btn_down = "-1" input_player1_btn_left = "2" input_player1_btn_right = "3" #Left Joystick input_player1_stk_l_x+ = "16" input_player1_stk_l_x- = "17" input_player1_stk_l_y+ = "18" input_player1_stk_l_y- = "19" #Right joystick (Throttle) input_player1_stk_r_x+ = "-1" input_player1_stk_r_x- = "-1" input_player1_stk_r_y+ = "21" input_player1_stk_r_y- = "20" #Left Shoulder buttons input_player1_btn_l = "10" input_player1_btn_l2 = "12" #Right Shoulder buttons input_player1_btn_r = "11" input_player1_btn_r2 = "13" #No idea what E1 and E2 buttons are for, but lets add them to the thumbstick buttons (R3, L3). input_player1_btn_l3 = "1" input_player1_btn_r3 = "0"

Works a treat! Thank you so much.

lr-opera worked on Lemmings with Player 1 as the mouse, it didn't occur to me to try Player 2 for Sega CD.

I've only had it happen on my 3B+ setup with the lr-genesis-plus-gx emulator. And it wasn't unique to megadrive games. I has some Master System ROMs also do it.

Hope they can resolve this in an update before long.

Hm, it might be something with the new RetroArch version and bezels. I don't have bezels in my installation, but I frequently use shaders, so I don't think the shaders have any influence.

Let's see if we can reproduce it.

@melbmatt50

Hmm...
bios.gg in the BIOS folder.

Try disabling threaded rendering in retroarch.
Launch run-command, make sure there are no setting that look awry, perhaps resolution; launch with verbose mode enabled, and try to get the log from /dev/shm/ posted to pastebin here.

Thanks - but I don't think it's a Dolphinbar specific issue. I can get it to crash with just a plain old keyboard/mouse switch too.

Doing a bit of debugging work I have found if I comment out this bit of code on line 2489 of libretro.c it no longer crashes. You lose the crosshairs obviously but otherwise it works fine, so it seems that something in the crosshair generating code is related to the crash. At least now I've got an idea of where the crash is originating from, I'll see if I can debug further and once I've got some better idea of the root cause I can post the issue to the core's github repo for further discussion.

Lines 2487 - 2490 on libretro.c

if (input.system[0] == SYSTEM_LIGHTPHASER) { //draw_cursor(input.analog[0][0], input.analog[0][1], 0x001f); }

@luisv96 said in Certain roms dont work on lr-genesis-plus-gx:

@mitu when i try to run verbose logging nothing happens

What do you mean "nothing happens"? Did you check the log in/dev/shm/runcommand.log ?

Please ignore this - I found out what the problem was, I'd turned on Shader #0 Filter to LINEAR. That is what was causing this effect in lr-genesis-plus-gx.

The repository has been updated and I can now build in x86_64

@edmaul69 got it. I didn't have ssh on, thanks.

Yeah I would rather the cue and not bin files listed. You can always add the extension manually though.

I am hoping that seeing as how supergrafx now supports chd format that it will make it's way into the genesis_plus_gx core..saves a LOT of space and tidies up nicely.

Won't have to worry about missing cues and no music ect...
