Today I published a demo of MSX.js emulator at

This is a MSX emulator 100% written in JavaScript. It's based on the jsMSX project and forked from the gmarty / jsMSX GitHub repository.

I got the sound working but the quality is not so good yet.

Thank you and any help is welcome!

Hi! Great work, welcome! I've tried msx.js with chrome and IE8 and there is no way to play zaxxon
Is it possible to upload a generic rom file ?

Tried Zaxxon here in Chrome and it works. I do have to refresh the page after a reset of the vtirtual msx.

I'll fix the reset buttom and improve/fix some other things, but, for now, the sequence is

1. Load a bios
2. Load a rom
3. Press start button
4. Play the game
5. Reload the page and repeat from step 1 to play another game

In IE 11 I can load the ROMs (expert_1.0_basic-bios1.rom and ROAD.ROM) and when I start the emulator the interrupt counter starts running, but the display stays black and I also don't hear any sounds.

In Firefox 26 I can't even load the roms.
