Fantastic!

Every now and then I look into MSX emulation on the 3DS and I'm always dissappointed - this looks like it cures everything!

 

[ber71]

Glad to see a new homebrew on the 3ds scene.
I've tested it for a few hours. So far, no big issues.
If anything, the menu is a bit too sensitive to dpad. Many times, it reads two presses instead of one.
An option to remember the last used directory would be handy, too. There is the a recently opened rom list, but it's not the same. Alternatively, a way to set the default directory, instead of sd root, would be fine.
The wide 800px option is a bit weird in 2ds systems. If you mess with it, you'll get a wiiiiide display wich doesn't fit. Yeah it's not mean for 2ds.
Sometimes, when opening a zip file, it asks for which file inside to load. If you cancel, the console crashes. Not always reproducible.

[Harry7228]

This is so exciting! I really wanted to play the original Metal Gear games, and any further emulators on the 3DS is always welcome. We should be able to make VCI's with this correct?

The fan Translation one,and the emulator is in the 1.1

while I have yet to test out snatcher on 1.1, I read in the readme that you need to select below load a cart, in the option menu, Load konami Scc+ Rom. Im not sure if their an order to it or you can load it at any time. I was able to boot snatcher on 1.0 I think withot doing this but idk. I think I used file open instead of open disk or cart.

 

[reddragon4000]

I feel like there's so much stuff missing on the Universal-Updater lol

 

[solidgui3]

Yea,It realy is,someone should update it

 

[N7Kopper]

The O2DS isn't compatible with HoriHD. Oddly enough, the N2DS is, despite it being an abuse of the 3D capabiliies.

 

[CrashMidnick]

Thank you !
