@barbudreadmon
I figured it out.. it was older retroarch mame cfgs
in the retropie configs folder.
I deleted them and it came right on.
No sound problems, no black screens.

@shift

Thanks, good to hear.
I am playing with it a bit and I could add it for more drivers this way from EXTRAS.
I will see how it evolves.

@mitu well, seems it was really that easy, I didn't do the update obviously. Sorry.

But as a warning to anybody else: I am pretty sure something is going very wrong at the moment. Compiling has been running since my last post. From the file names I think the games that were in scummvm folder are beeing processed aswell... Which I don't believe should be the case :D won't abort this now, I will check the result.

@mitu said in Display frontend on VGA666 CRT instead of HDMI with Pi4 and KMS:

Thanks for taking the time to answer!

I'm surprised this configuration worked with fkms, but I think it's no longer going to work on kms alone. I've seen your - similar - post on the RPI forums, the definitive answer if this configuration is supported should come from a RP engineer (6by9 is their expert on this).

Yeah, that's the first place I asked. I was hoping it was some stupid mistake on my side.

EDIT: one thing to note, the RetroPie image is currently based on the legacy RaspiOS buster version, a lot of work has been done on the pure KMS driver on the current Linux kernel. You can get the current RP Linux kernel with rpi-update (not recommended) or by manually installing RetroPie on current RaspiOS bullseye (still in beta at the moment), my recommendation would be the latter.

I did try a rpi-update as an extreme attempt, ready to start from scratch. Unfortunately the situation didn't change.

The other idea is to have a second Pi driving the marquee, which is a solution I have mostly working with one last annoying quirk that I wasn't able to iron out yet.
It would be great to do everything from one device though.

I guess you're using the RetroArch master for the switchres support added after v1.15 ?

Yes that's correct. And it seems to work great, possibly much better than the "old" Pi3-style runcommand trickery based on fbset and vcgencmd.

I remove lr-mupen64plus-next and lr-ppsspp from retroarch setup.
I install it again and it works ! I can go into the rgui menu (strange thing i mapped hotkey on the xbox button and i can with select + Y !!! (but i can !).
With another emulator (lr-beetle-psx, i can quit a game with select + start.
Not from fresh install emulator. Have i something to parameter in rgui menu

Regards.

@top-specci So when you said "this is the solution" to @sleve_mcdichael 's suggestion to press the button "shortly", you actually meant it didn't work ? It was a bit misleading.

Does it work if you plug a keyboard and press the "lshift" key ?

@Lolonois It installed. Do i need specific Bios files in a certain directory on the pie as the game kicks right back out, super fast, to ES when i try to launch a game/disk with lr-apple2win.

@orbian No problem. Glad it worked. Keep them all in that folder, you'll find its a lot easier that way

All is working as it should now, thanks again!

@genos98 Yes.

@roslof Thanks! I've figured out to change the .ini file so I've got full control now. :)

Rip your CDs as cue/bin files directly. Verify the files are correct by comparing the checksums for the .bin files and the .cue file's contents with the ones published on redump.org. You can use ImgBurn on Windows to rip the disc to .cue/.bin files.

@yfzdude Totally worked. Thanks for pointing out the doc.

I don’t know how to mark this post as [solved], but I’ll try to make a summary of the lessons learned here anyway:

lr-fbneo-msx needs all MSX BIOS files in on pack named msx.zip in /home/pi/RetroPie/roms/msx/msx.zip lr-fbneo-msx needs ROM files to be zipped and verified against DAT checksums (the filename and CRC must match) MSX ROMs that are downloaded together with lr-fmsx does not work with lr-fbneo-msx (CRC are different for all files); you have to find the right BIOS files elsewhere. I still unable to load ROMs with lr-fmsx (however lr-bluemsx is a good alternative so far) In lr-bluemsx you can use the keyboard in MSX if you add a input_enable_hotkey in /opt/retropie/configs/all/retroarch.cfg or /opt/retropie/configs/msx/retroarch.cfg:
input_enable_hotkey = "tab"
Normally you would press "F1", when enabled you have to press "TAB + F1"

Thank you @mitu and @Folly for your help!
Happy MSXing

@sega-dude can't you just install the binary from the experimental package list?

@mitu got it, thank you! thumbsup
