Okay, thanks. I will probably just redo the configuration stuff, but make sure I get all the roms, boxart and metadata carried over. I have another SD card I can experiment on, so I'll give it a go.

OK, thank you for your answers !

@theroamer
Sorry was on holiday the last days without internet. Happy that everything works for you too. Any progress with kodi controls?

Aha! It is the non-LR mupen emulator then. It always takes me 2 tries to get that to compile for some reason. I will give it another shot tonight.

As for OC, I'm done with OC on the RPi3 for now. I have tried everything and none of them were as stable as the vanilla clock speed. I may revisit it once I give the above a shot again. Thank you for your hard work, videos and contributions to this community. I subscribed to your channel.

Thank You! I found it.

Hopefully I'll finish it! I'm still a little skeptical everything is going to work out as planned, but so far so good.

you are just seeing the end of the boot sequence. Depends on speed of sdcard etc how quickly the machine boots, but the splash is on a timer.

Yes haha it took me a week or so to learn the magic of the sudo command

@tdodm

These emulators are not 100% cycle-accurate, but they're pretty darn close. Outside of a regional rom issue, any change in timing would be almost imperceivable. Also, if there was a speed shift, you would notice a change in the music and basic game play as well.

@herb_fargus - thanks for that :)

My version of scph5500.bin has the correct MD5 checksum of 8dd7d5296a650fac7319bce665a6a53c and the CRC32 checksom of ff3eeb8c

I think it might be a filename issue. I'll experiment with added a dash in it like scph-5500.bin

Edit:
I've tried many filename cases but non seam to work when trying to play Japanese games but I did find out that it really doesn't matter what case the BIOS files are to play the US games and also worked with just about every BIOS version (US games playing with any J, E and U BIOS files 10x, 100x, 300x, 350x, 500x, 550x, 700x and 750x). Some US games will even play without a BIOS file but it gives a quick message stating "no BIOS found, expect bugs!"

I'm testing with 2 Japanese games: Captian Commando and Nekketsu Oyako. Maybe neither one of these work with the emulator.

Does anyone out there have any Japanese games working and which one(s) did you get working?

I don't know what your setup is so I'll assume it's exactly the same as mine. https://retropie.org.uk/forum/topic/3/read-this-first

In your retroarch-core-options.cfg file, what are your below settings showing? Mine are set to the following. These are all default though so I don't know why yours would be different.

gambatte_gb_colorization = "disabled"
gambatte_gb_internal_palette = "GBC - Blue"
gambatte_gbc_color_correction = "enabled"
gambatte_gb_hwmode = "Auto"

edit: i tried another usb stick, and it's working fine again, so we'll just use that!

@aaaccc1 it shouldn't, but always wise to backup as mentioned on the wiki

I have modified the configure script for advancemame to avoid this. In general configs are not overwritten, but there may be a few cases we missed with older emulators.

@hansolo Just wondering if you found a solution to your problem? Basically I want to have multiple controllers plugged in as player 1 so if I don't like the controller I'm using I can just grab another one as I'm playing a game. Thanks.

@thrussmeister
With arcade games, there are a variety of resolutions and aspect ratios to consider, making bezel overlays a difficult choice unless you run on a per rom basis, and use overlays like this:
http://libretro.com/forums/showthread.php?t=5085
Although I suppose you could just use a non-bezel based 1080p overlay to cover the lot, like this style Scanlines_4x_1080p_Borderless.cfg.

So instead try using a shader, you can apply using

video_shader = /opt/retropie/emulators/retroarch/shader/crt-pi.glslp video_shader_enable = true

in the emulator/system based retroarch.cfg
