New Online MSX emulator

Hi guys!

First of all, thank you for the awesome response and feedback! Please keep them coming! I will post here when I release new versions, with possible solutions to the issues found.

Being a software that will be run in every Browser/Platform/OS combination, its VERY VERY challenging to make it work equally good in all of them. Please bare with me! And keep in mind that I do much of my testing primarily in Windows with Chrome, them some in FF and much less frequently in other combinations like Linux, OSX, etc... So if you guys have the possibility to try it in Windows/Chrome, with a relatively good machine, that is my primary target.

Other browsers, for instance, like IE do not even support some of the technologies I am using. Sound and joysticks for example will be completely disabled in some browsers.

Also, I see we have very experienced MSX people here. So if you have any idea of "why" the emulator is having some weird behavior, please let me know what you think may be the cause, or give me hints! You see, I made this emulator but I do not program anything on a MSX since I was 14 (and yes I am over 40 now :-).

Sorry, but I'm not much of a "community guy", so I generally don't know much people of the forums and I do not follow things in the scene closely. The language barrier also get in the way a little. I am more of a "programmer hermit" :-)

So, I do not know the majority of the newer MSX software written. I can remember really well the games I played when I was a kid, like Goonies, Zanac, Eggerland Mystery, etc. So those are the titles I first tried to run with perfection.

Well... Thank you for all the reports. I will try to answer every single one of them and try to give a solution in the next releases!

I am now working in line-accuracy for the next release.

Thank you guys!

Hum, I see... I have a feature for multiple keyboard layouts, but for now it only supports en-US and pt-BR. I plan to add more. So I guess ES will be the next one. :-)

For now, you can try to use your keyboard like a US layout keyboard. Then you will be able to enter any character.

One other thing you can use to start CAS images is the "auto-run" feature. Whenever you load a CAS image while the machine is OFF, it will automatically power on, detect the software at the current tape position, and load it!

You can also press Ctr-Alt-Shift-F8 or click the litlle "Cassette" icon on the bottom bar with the middle mouse button while the machine is ON, and it will type the correct command to run the program automatically.

Regarding the screen, that was not supposed to happen. It should auto adjust the HEIGHT to your screen, and leave black bars on the sides. Can you tell me what screen resolution you are using?

About the 48K ROMs, I will look into that. Can you give me any mainstream example of such ROM so I can test?

Did you try to open the CAS image with F8, or drag and drop the file while the machine is OFF? It will not trigger auto-run if the machine is ON. Its not safe for the emulator to reboot the machine automatically or type anything with no warning if you want to change tapes on the fly while some software is running, so it will do that only if the machine is OFF at the moment you open the CAS image, or if you open it with Ctrl pressed! (alternate Auto-power, its in the Help screen).

Ok, will try them! Thanks.

Yest that is EXACTLY how it works! You can pass URL parameters like "rom", "cart1", "diska", "tape", "state" and even "bios" and point to a URL containing the file. The emulator will automatically load and play them.

But remember that unfortunately, the Browser cross-site security policy will not allow the emulator to download files from a different domain. So those options are intended for websites that wish to offer the emulator and auto-load games from the SAME domain.
You will not be able to, for instance, launch the emulator from my official website pointing to a ROM file from your own site. It will not work like this. You will have to put your own WMSX served in you page, which is the right thing to do anyway.

But you where right on the spot! Those are already implemented and working. :-)
I just have not written any documentation yet.

This makes possible to put WMSX running software in any webpage very easily. You can even make the emulator auto-start a Savestate file directly in action. Is that cool or not!

no scc support? would be nice if the roms and disks could be loaded online rather than from local pc

Boa tarde!

Necron, can you please tell me your machine specs? Operating system, browser type/version, etc.
You're maybe having a speed problem, or maybe too many browser tabs or open programs in the background?
If you can, please try to do a "clean" test.

MSX emulation in Javascript is kinda heavy stuff! :-)
