I just started to begin with DSi Emulation, using lr-LemonDS, and came to the point the tutorial ends: games will only start via the DSi-Menu, so "boot directly into rom" has to be disabled in the core-options.
Only difference: i have full access to the DSi-Roms in the /ROMS/DS-Folder from there and dont have to use prestuffed NAND-Files (would also be a fishy way imo, not the way it should work)

And this is an issue:
first of all on the official FAQ-Board it is recommended to keep this option at its default (=off/boot into rom), in special when the DSi-Bios is used.

Secondly the Retroachievements for DSi-Games only launch up when booting directly into the rom, you can see the widget, everythings fine.
Only problem: the screen keeps being white and silent.

Booting into menu works as mentioned, so the BIOS-Files are good for sure.
I can start all my games from there, but without Retroachievements Support, so i hope to find a way to boot directly into the game (as it should work :)).
I allready tinkered with further core-options, but had no luck.
If anyone has an idea it would be much appreciated.

It works on the 2010 MAME core in Retroarch.

Looking for a save for this game (MK2Plus) and UMK3Plus with complete unlocks. For Retroarch FBNeo Core.

The ones from Fightcade's FBNeo emulator don't work... I get a CMOS error, which makes it go back to default factory settings.

Can anyone provide a hand? It would be greatly appreciated.

Hi there, I stumbled upon your project while searching for STL files for the ATARI ST 520 case. I want to put in a MISTer FPGA in exactly the same case as you project, would you by any chance considering making your 3D printed parts public or sending them over? It would help me quite a bit, your configuration would be a great starting point 😊

I've already completed an Amiga 500 MISTer mod, but the Amiga needs it's historical counterpart 😊

@Plantor07 been literally dealing with this for days with 8bitdo and Stadia. Tried this and it worked for me.

Just came across this script, very nifty, but can't log in. The login window on my browser just keeps popping up after I enter my credentials. I've verified that the service is running through Terminal. Any suggestion? Python, RetroPi, etc are all up to date. Running on Rpi4. I updated/changed the login credentials, but should still work.

@hoeveler Hi, yes, you are right. It has greater access to the GPIOs and supports additional controller types besides arcade. Also, it does not have a DAC/amp.

BTW: Is the DAC/amp an important feature in your case?

Hi! Does anyone know if it's possible to set the the to look as the "multi artwork" version? Or if there is any alternate version? Thanks!

@Unknown Late to this thread but what about XEMU? https://xemu.app/

In case you have not found it yet by yourself: [1] discusses this.

TL;DR you will need some extra circuits (monostable circuit or timer IC NE556) to do this.

And in addition to the StackExchange post you will also need a circuit for the falling edge of the latched switch.

Then you can use the "momentary switch approach" [2]

Thanks for the help and advice so far

I did manage to resolve this by -

1). Installing the PINN multi-boot software from the Raspberry Pi Imager

2). Using PINN software to set-up a dual boot set-up on the SD card

3). Installing -

3.1. Raspberry Pi OS
3.2. Retropie OS

4). Adding the various games and ROMS that I wanted on each OS / partition.
