Just a minor problem, it has the same title id as blargSNES
Out of curiousity, could the source and homebrew executables be put on github so they can be made available in Universal Updater so it has a chance of reaching even more people?
(Given just how good the emulator is in my opinion and probably for other people as well given that it means no longer needing retroarch for MSX)

v1.2
-Add support for MSXTurboR!
Good news for New3DS user. I tested many MSXTurboR games/ apps and all of them works full speed at 60fps on New3DS.
And bad news for Old3DS user. Most of MSXTurboR games/apps runs slowly on Old3DS.
It can't be helped because MSXTurboR has over x8 faster CPU than MSX2+.
But, silver lining is that many enhanced patched game work better with MSXTurboR and most of these games works full speed even on Old3DS.
You need MSXTurboR BIOS files to run MSXTurboR.
If you are using BlueMSX core for retroarch, fMSX3DS load it's BIOS files directly and no need for setup BIOS files.
If not, Copy following MSXTurboR BIOS files to the ROOT of your SD card or "FMSX3DS" folder("root\FMSX3DS").
MSXTR.ROM
MSXTREXT.ROM
MSXTROPT.ROM
MSXKANJI.ROM (A1WXKDR.ROM, KNJDRV.ROM)
MSXDOS23.ROM
MSXTRMUS.ROM
-Add support for PCM voice sampling of MSXTurboR
-Add support for MSX-View font and pseudo MSX-View font from A to C for MSXTurboR.
-Add support for MSX-View for MSXTurboR.
-Other MSXTurboR additional feature(MSX-MIDI and PCM microphone)doesn't support now.
Please wait for sometime.
-Removed unsafe option item "Load MSXDOS2" that makes many MSX-DOS1 disk games to go wrong (Snatcher etc).
If you want to use MSX-DOS2, Use MSXTurboR that can use MSX-DOS2 with more safely.
Or, simply opening MSX-DOS2 rom file with "[File Open]" menu enable you to use MSX-DOS2.
-Fixed bug that sram crahes infrequently in some KOEI games(Nobunaga no Yabou Sengoku Gunyuu Den etc).
-Fixed bug some game doesn't work due to sprite collision error(The Goblin(MSXdev23) etc).
-fixed bug that ESE-SCC doesn't save S-RAM when you reset MSX.
-Fixed bug that fMSX3DS has same titleID as other 3DS app.
-Fixed Z80 CPU flags for block transfer opcode().
-Add support for horizontal hardware scroll emulation in Screen Mode3 in MSX2+, MSXTurboR.
(F-nano2 etc).
-Fixed bug that horizontal hardware scroll emulation in Screen Mode4 in MSX2+, MSXTurboR go wrong in some case.
-Improve GUI menu for reset MSX to move cursor to currently selected MSX machine setting automatelly.

v1.3
-Add support for MSX0. fMSX3DS is first emulator to emulate this.
MSX0 is new offical MSX project start at 2023.
MSX0 can connect many kind of IOT devices and control these with MSX
,and many people make homebrew or doujin game/app with this feature.
To use MSX0 with fMSX3DS, Choose "[Option]" item in the fMSX3DS system menu, and enable the "Use MSX0" option item.
fMSX3DS use fake MSXIOT ROM file for MSX0 and you need no MSXIOT ROM file.
But, some MSX0 games/apps requires MSX-BASIC KUN(X-BASIC) ROM.
If you are using BlueMSX core for retroarch, fMSX3DS load it's ROM files directly and no need for setup X-BASIC ROM files.
If not, Rename MSX-BASIC KUN PLUS(X-BASIC2) ROM to "MSX0_XBASIC.ROM" or "XBASIC2.rom" and copy that to the ROOT of your SD card or "/FMSX3DS" folder.
Then, Choose "[Option]" item in the fMSX3DS system menu, and enable the "<MSX0 Option>/Load X-BASIC2" option item.
-Add support for touch screen of MSX0.
You can use it with touching the mouse icon on the lower right of the bottom screen when you enabled the "Use MSX0" option item in the option menu.
Then, you find MSX screen at Nintendo 3DS's bottom screen, then 3DS bottom screen works as a touch screen.
-Add support for Accelerometer device for MSX0.
You can use it with Nintendo3DS's accelerometer.
-Add support for Encoder anlog input device for MSX0. fMSX3DS emulate this with Nintendo 3DS's 3D Slider.
To use this, Choose "[Option]" item in the fMSX3DS system menu, and change option item "<MSX0 Option>/MSX0 Device A(i2c_a)" to "Encoder(3Dslider)".
-Other MSX0 devices such as microphone or LED light or internet connection(wifi etc.) or buzzer etc. doesn't support now.
Please wait for sometime.
-Fixed bug that CLOCK-IC get invalid value in some game/apps(chikuwa watch etc).
-Improve PCM voice sampling for MSXTurboR a lot.
-Add support for touchpad device for MSX. fMSX3DS emulate that with nintendo 3DS's touch screen.
To use this, Choose "[Option]" item in the fMSX3DS system menu,
and change option item "<Input/Output Hardware Option>/JoyPort A" (or "JoyPort B") to "TouchPad".
-Fixed bug that mouse icon and keyboard icon doesn't work if you insert a Mouse to joyport B.
-Add support for ".DSK" file of 5.25inch 1DD floppy disk image(Philips Video Graphics etc).

Any chance of getting Yamaha V9990 support for games that make use of it? (Life on Earth being one of many homebrew games that require it), and the only emulators that currently support are WebMSX and OpenMSX
could there be a possible way to have a lower quality setting for yamaha music so games with yamaha music in them can run better on old3ds at the expense of not as good sounding audio. Its a trade id definitely be willing to take. If this isn't possible, that is fine. Regardless ,I'm glad to see work on this project still get done.
I'll try that.but, I can't guarantee anything because I don't know whether Nintendo 3DS has enough CPU speed to emulate that or not.

I still woring for speed up emulation especially yamaha FM sound in old3DS.
I tested your idea, it increase speed by by 20%.
Great improve , but more improve needed.

I accidentally made the mistake of setting the emulator to boot at MSXTR mode on startup, and now fmsx3ds crashes whenever I try to open it. It'll open, hang on the keyboard for a sec, and then boot me back out to Homebrew Menu. I've tried deleting the entire directory and reinstalling it, and it still does it. There is no config file in the directory or anywhere else to even delete, so I'm clueless.
EDIT: Nvm. Didn't realize it creates another directory at the root. Fixed that problem. However, it's still a problem with the emulator itself. TurboR mode just in general doesn't seem to function on this emulator at all -- so not sure how it's touted as a feature -- nor do the SCC & SCC+ sound cards. Sound in general seems to be something of a glitchy mess on this thing, often missing certain sounds in certain games, and overall just a little too low-volume. Can barely hear the the thing at all if I'm in a moderately noisy environment. Could use a volume boost a couple decimals. Then when I ask it to force the SCC+ soundcard in the emulator settings, I get nothing but the same standard PSG sound, but now missing a few layers or channels of music -- or no sound at all -- for my trouble. Is this a me-problem? or is everyone else having these issues, too? I'm using a New 3DSXL.
Other than that, it's a really nice emulator. But we're not quite there yet. V9990 support in the future would also be nice, as there's a handful of modern MSX homebrew where it's required.

I think I remember there a way to improve the sound quality of scc games. Forgot how it goes, but ive done it. I have experienced the same issue with turbo R though
Sorry for crash bugs for MSXTurboR.
I will fix that with the next update.
>TurboR mode just in general doesn't seem to function on this emulator at all
I guess you troubled with MSXTurboR BIOS files.
Caution that fMSX3DS can load BIOS files from BlueMSX core for retroarch,but in some case it does'nt work.
If so,you need these files to place in "FMSX3DS" folder at the root of SD card.
Please confirm its filename and filesize.
MSXTR.ROM (32KB)
MSXTREXT.ROM (16KB)
MSXTROPT.ROM (16KB)
MSXKANJI.ROM (32KB)
MSXDOS23.ROM (64KB)
MSXTRMUS.ROM (16KB)
Okay, thank you. After something of a wild turd hunt to track those files down, I did as you said and that has fixed the issue. I also set Turbo R as my console on start-up again, and it no longer crashes on start-up. So, those missing files must've been the culprit.
Thank you for this gift in development.
I've really been enjoying exploring more software for this odd little Japanese computer. Even bought Dim X and cranked on the 3D feature.So, another question I would have in light of this would be in regards to the BIOS files for the MSX/MSX2. Because I actually had those BIOS files already, as they were required for the original MSXDS emulator on the DS, and I dropped them all in the Root>3ds>fMSX3DS directory as opposed to the FMSX3DS folder in the root. Are they of any use at all in that directory, or is fMS3XDS indeed loading the MSX/MSX2 BIOS from Retroarch?
And I guess in regards to the sound issues I'm having... apparently it is often a general issue with certain fan-translated-English ROMs themselves. Tinkering between certain settings -- such as forcing the SCC+ soundchip -- has varying results. Fixes certain things in one game, breaks certain things in others.
Post automatically merged:
With the SCC+ soundcard, perhaps? Don't know of any other way you could possibly improve the sound apart from using a potentially superior soundcard that the individual game was programmed for.
I've explored this issue a little more, and apparently a lot of English fan translations romhacks just have inherent sound issues, such as the Project Melancholia English translation of SD Snatcher. Apparently, the SCC & SCC+ sound cards just straight-up don't work for it on most emulators. I myself always get the PSG sound, even when the game detects the SCC+ card and I command it to use it. Apparently someone devised a fix for this issue in Retroarch using dummy soundcard files. I downloaded them and threw them in the appropriate folder directories in fMSX3DS as well as in the Retroarch directories, and it hasn't made any difference. However, *not* forcing the SCC+ soundcard in the fMSX3DS emulator options settings leaves the sound in SD Snatcher broken. Enabling it at least fixes the standard PSG sound. But then, alternatively, forcing the SCC+ soundcard breaks the sound in Metal Gear 2, and disabling the setting fixes the sound in that. So, there seems to be a lot of individual idiosyncrasies regarding various MSX ROMs in terms of sound.
But certain games are still missing certain sounds/sound channels and whatnot, no matter what I tweak in the settings. And just generally, I feel like the sound is really low and subdued on this thing, even when I got the 3DS volume cranked full-blast.

Thanks for this super cool and niche emulator! I wanted to report a major bug I encountered in MSX2 Dragon Quest 1 (specifically with Django's partial English translation applied):
After speaking to the old wizard in the starting castle area who rapidly flashes the screen with light after speaking to him, the color palette of the entire screen became incredibly washed out, with not even resetting the console or saving in-game making it go away on that save. Only starting a new save got rid of it, but when I went back over to him, it happened again. I'm pretty sure that's an important NPC, too.
I also had a couple questions and some feedback:
-Why does the "no scale" option under the "screen stretch" option display the image in the corner of the screen instead of the center? Is there a way to center it?
I also remember that another option, I think "keep aspect" when the separate "screen filter" option is disabled, made the image about 10 pixels horizontally off-center.
-The navigation sensitivity in the emulator settings menu is very high, meaning you have to be actively careful and precarious during basic navigation for it to not fly all over the place. A similar thing happens with needing to very quickly jerk the stylus away from the touch screen to not accidentally select, say, the wrong MSX model mode to reset to when using that screen/the virtual keyboard on it to bring up a menu. I think the sensitivity should be adjusted to match digital UI standards where such issues don't exist, and the user doesn't have to exert such vigilance.
-Whenever you exit and re-enter the emulator menu, it has no cursor memory and doesn't remember where in the menu you last were. Having to navigate through the entire menu from the top to get back to the function you want to use every single time quickly gets tedious, especially for the save state and screenshot menus all the way at the bottom.
I think that cursor memory should be implemented, and pressing the B button/bound "back" inputs should just take you back one menu layer (with cursor memory for between layers, too) instead of backing you out of the menu entirely. The start button/touchscreen/etc should be what's relegated to an instant exit. All of this would further align with menu design standards.

I just did the same thing as you. I can't say that was easy either. Thanks for running in to this issue before me so it was easier than otherwise would be to sort out!
I agree. This is probably one of the most mature and robust emulators for the 3DS. I've been having a blast checking out the MSX through this thing. It amazes me that so many things I thought originated on the NES actually got their start on this computer. It's also neat to see the progression of companies that exist today because of this.
v1.31
Immediate update for bug fix.
-Fixed bug that fMSX3DS can't boot if you setting the emulator to boot at MSXTurboR mode on startup with missing MSXTurboR BIOS files.
-Fixed bug that fMSX3DS crashes in MSXTurboR mode with you missing "MSXDOS23.ROM" file.
-Add new option item "Sound Volume".If you feel volume is too low, increase this.
-Adjust sound blace of Y8950 to get rid of noise in too loud Volume.
-Improve MSX0 emulation to show hardware info with linked with your 3DS info(Battery level, heap memory, wifi strength etc.)
-Fixed bug that fMSX3DS can use some MSX0 feature even if "Use MSX0" option is off.

Thanks for report.
As to Dragon Quest 1, It will take some time because i have to play english translated Dragon Quest1 to find a solution.
