I love this emulator, but how come it doesn't play sega master system games? I want to play some wonderboy 3 the dragons trap.

dont like the lag

Gba games lag a lot...

It sucks so much i play 3 Fucking hours save a lot of times load a lot of times, leave the game come later back and 3 hours playtime are away and there is a old save. For what i haveDonate

and if you wait a little longer the save disapers completly

I had this problem to but the solution is very simple. you just need to backup youre savefiles somewhere on youre computer. there should be a way to do this automatically but I don't know that for sure. so, just backup youre file. if it corrupts, delete it and put youre backuped file in icloud. then it schould be solved. good luck.

There is a ugly bug with the saves.

Whan i save a game and load it all is nice but whan i save and leaf the game fore a while and come back it loads a old save but whan i look on one drive there is only one save how is this posible.

I looked down the comments and a lot of ppl have this Problem.

What can i do that my save is save

cant save Mega Man X2 and X3. Also Developer busy, doesnt look this site

how come the onedrive button does not appear anymore?

Might be a stupid question, but 1. can i actually play this on my xbox one and 2. how xD

1. it is a dumb question, and this only works for xbox one unless you have an xbox controller connected to your PC, and to get here on xbox just go on the web browser, duh

well that was rude 😂 but yh I figured it out already 👍

Good website for getting ROMs? (Or however you get ROMs, I'm new to this stuff)

(Edited 1 time) the game,open zip n extract,and upload the file to ur OneDrive. as it won't pick up the folder n enjoy feel free to ask questions

Should I be worried about any viruses? I'm pretty cautious about these things...

Also, after I logged into my OneDrive, it just takes me to a blank page (I checked the HTML, there was nothing there, so it wasn't a loading error...)

The link

No don't worry about viruses Ive never had one from emuparadise and any further questions just ask and I'll try my best to answer

Thank you a lot! I've been playing the original Zelda, along with Ocarina of Time. (Also downloaded a ps2 emulator, and the original Fallout, been a lot of fun!)

You're very welcome mate

how is it going any progress ??

just curious is anyone else having an issue with mega man x. Ive downloaded different versions of it and all of them allow me to play 1st mission and select the next area but once i make it to the boss itll just say that i beat him kick me out and start the 1st mission all over agai

download v1.1

Hello, is there any way to adjust speaker volume on Genesis and SNES? On both systems I have bad speaker pop throughout games. No problem with NES audio. Program is so awesome other than that!

Please developer, I discovered a Genesis button mapping error. In games using 6 buttons as in Ultimate Mortal Kombat, the Y button is mapped together with the C button and so failures occur and there is a missing button to complete the mapping control of Genesis in all games that are used 6 Street Fighter , Mortal Kombat among other fighting games. I made this discovery doing tests of all possible ways to correctly map the 6 buttons and I was always missing the 1 of them, X, Y, Z and ABC are all but Y is synchronized with C and it is as if we were using the 2 in 1 button only. Thanks if you can correct this will be perfect the Genesis Emulation.

Is there a site where I can download .nes .smc .sfc .gen .smd .mb .bin .gba .gbc .gb files? Because emuparadise only has zip downloads and I can't seem to find a way play these games....

Try opening zip files, very intresting huh?

Why not Master System?

@nesbox hey guys, any news on the save+OneDrive fix ? I'm really looking forward to it !

How and where do I get the roms to play as it says file empty

Is there any way to increase the game count from 200? OneDrive holds up to 5GB by default but nesbox only registers the first 200 roms. I would love to be able to have every game available to play without having to delete roms to switch them out with different ones! Either way love nesbox!

its start to not save. i was saving nice before

Could the NESbox UWP app support the same kind of cloudsave? I'd love to play from one to another. Using Edge doesn't really work for me, as I it does not support keyboard and I don't take my controller around.

Best app ever!

Is there a way to map C and Z in the xone app?

what does this do?

You are the best great work!!! some questions:

1)extension needed for the saved states files to load on 1drive to work with this emu? maybe in next update enable to load saved states?

2)i know you say no but PLEASE consider n64 emulation

3)donations to keep the project going???

My game was partially saved because I was playing Pokemon Gold and my Quilava was at level 24 and now it's back down to a Cyndaquil at level 13 or either that it just randomly selects a save. Please fix

I downloaded the Namco Museum for the GBA the graphics are a bit wonky but the fps is terrible.

yes, seems to browser doesn't have enough performance to emulate GBA

So GBA is more powerful than SNES, intresting. Cant you make app to download for Xbox Developer mode?

Can you do a MAME version like this?

It's possible but I'm not going to add new emulators, sorry


N64 Emulator would be awesome!

This is by far the greatest app ever! If there is one thing i have an issue with is the screen seems to be cut off at the bottom.

I would agree, some games like mario land on gameboy the bottom of the screen is cut off so you can't see where actual floor you can walk on is, or if it's a hole... if there's anyway to slightly adjust screensize that would be awesome...

know about the issue, will try to fix


will you be adding new emulators

not going, sorry

can you fix the gameboy colors i want it black and white

there doesn't seem to be a way to use the C button when playing sega genesis games. please fix.

(Edited 1 time)

please fix street fighter alpha 2 snes it's not working right and the emulator needs a little update fix the bugs and audio

Will you be adding the Sega Master System to this emulator? It would be great if you did. Thanks again.

This is awesome. I get to play the games that started Nintendo's popularity. I even got to play the finished but unreleased "Star Fox 2". Now, Would it be too much to ask for a N64 and 64DD emulator for Xbox one? They removed win10e from the app store before I knew about it. Also GBA lags too much for me, everything else is fine expect color on GBC.

GameBoy ROMs don't load correctly

Incredible job, thank you so much, wish you find a way to download it to Xbox. But anyway cant play Genesis games, its says "Developed for use only NTSC Genesis Systems or PAL Mega Drive Systems"

try to add (E) postfix to the rom name

gamename (E).smd' for example

It worked, thank you so much. You are awesome. You should make a UWP Arcade emulator for W10 devices. Like MAME. Of course it will work if Microsoft allow to Windows Store.

the emulator don't work

have you given up or are you working on it ? no complaints just wondering

not yet, sorry

I'll announce when I fix the save issue

when i played mega man x i szved my game ahd when i come back it was gone please fix it

Yeah, this issue is really critical for a lot of users/players here. Unfortunately most of the games have some kind of progression and loosing it is really awfull. Plz try some workarounds or anything else, but plz solve this issue. Have some many games that I want to play but I'll not till tis get fixed.

fix your grammar, leontada.
