I just got fMSX compiled and running on my N3DS, if anyone's interested (hurray MSX Metal Gear and Metal Gear 2: Solid Snake!). I would've gone for blueMSX instead, but it has a bunch of undefined references to "glob" and "get_crc_table" or something, so I stopped messing with that for now. I didn't have to make any source edits to get fMSX to compile, just a minor makefile edit. The controls don't seem to do anything, though. Looks like I might have to make some edits somewhere (or I guess end up doing a separate port that includes a touchscreen keyboard or something)..

Having trouble with the Retroarch MGBA on N3DS(3dsx) for Fast Forward toggle/hold. I've no idea if it's working after binding it, Vsync ,Audio sync off, and FPS goes up to 60->90 on PKEmerald, but it's not nearly the fast forward speed I was hoping for if it is working. I have it at 10x maximum speed in the options, from what I'm guessing is the correct place to edit it, and I can't seem to find a frame skip option to see if I can make it faster. I'm extremely used to the speed emus like VBA, and GameYob have when you hold fast forward, and would like to have that type of speed.

Okay, here's an unofficial "port" of RetroArch's fMSX core. I haven't figured out a way to save games yet, so this is more of a proof of concept than anything.
Don't ask for tech support for this build, I just wanted to show that fMSX can run on the 3DS just fine.
The control bindings are as follows (mainly hard-coded for Metal Gear 1 and 2; unfortunately, MSX games don't have a standard control setup as far as I know):
A: Joystick button A
B: Joystick button B
X: Keyboard button F3
Y: Keyboard button spacebar
L: Keyboard button F4
R: Keyboard button F5
Directional pad: Joystick directional pad
Start: Keyboard button F1
Select: Keyboard button F2
To set it up, grab all of the ROMs from https://github.com/libretro/fmsx-libretro/tree/master/fMSX/ROMs and stick them in RetroArch's system folder, like you would any other BIOS files. After that, grab a ROM for your favourite game (I only tested Metal Gear 1 and 2) and enjoy. You might need to set the machine type in Core Options -> MSX Mode to get different games working. Metal Gear 1 and 2 run fine with MSX2+.
As for source code, I'll just post the tiny edits I made here, so you can reproduce it from scratch:
Retroarch's /ctr/Makefile.cores (add this somewhere in the big chain of platform comparisons):
In fMSX's libretro.c (make joystate global):

Metal slug3 is not going to run right now, did you see the size of the rom?
any way, please state build type (3dsx/cia) and and system(o3ds/n3ds) with every posts.
I'm curious to know how well fMSX runs on the old 3DS/2DS. If it runs decently enough, I'm almost thinking of making a standalone port or an emulator from scratch maybe. The MSX is a fun little computer.
Thanks for the answeer.
The rom I'm trying to load is Neo Bomberman.
o3DS, .cia build.
I just tested PSX core and wow, I wasn't expecting to load every game I put into it, the speed is ridiculous but man, is still amazing to see it running.
Anyone who's having problems with cps1 cps2 and neo geo roms working try them from here. I'm not linking any roms just the site if that's ok. It's in French this site just click on the right hand side arcade section. This site has all of them and only a few didn't work for me. Get the main zip and not the patches.

, Reason: DO NOT LINK OR MENTION ROM SITES ON GBATEMP
To add to this, I seem to have an issue where no retroarch configs are saving despite hitting Save New Config -> exiting afterwards to try to make sure they are saving. No saved configs can be found after restarting, and settings have reverted. I can see in the debug they are saving to the proper location, but that doesn't seem to hold true.
EDIT: It doesn't seem any settings are even be saved, when they are saved. Loaded many different configs and everything is always reset in them.
Save at exit is ON, etc..

AWESOME WORK. Thank you.
Did you make a pull request with your changes so the Retroarch team can add it into the official nightly builds?
Hope so!
you can't load/save configs manually currently.
just don't touch those and config will load and save fine by itself.
@daxtsu, yeah where is that PR ?

@SylverReZ I've never used a disposable, seems like a waste. kinda cool idea tho. It would be nice to have vape built in to a cell phone even. "The iVape"+1 -
