MSX games can be considered abandonware, but, that means nothing commercially/legally speaking.

There's a spectrum emulator at the official app store (I have it, BTW and Auf Wiedersehen Monty rulz), and even games being maybe older than MSX's games, emulator author have to sign individual license contracts with whoever still hold that specific game rights.
In my opinion, several MSXDEV developers would allow the author to freely distribute the games along with C-BIOS. I'm pretty sure that, even with this games, that would represent huge sales...
Maybe a donation to MSXDEV prizes based on a % of sales would be a great incentive for new games to be added to the package.

How about that?

Hi everyone, I'm the developer of the upcoming MSX.emu for mobile platforms. First of all thanks to everyone for having an interest in this app and to kaziebo for getting the idea started Smile

Now about the choice of using BlueMSX, it's mainly because I've used that emulator in the past and was more familiar with it. However, my app's front-end code is flexible enough that a different emulation back-end can be swapped in at compile time by just hooking up certain functions most of the time. If there's a demand for OpenMSX, I can certainly port it as well though I'm not familiar with what pros/cons it has compared to BlueMSX. The main issue with mobile devices is using the least amount of CPU while maintaining good compatibility so if OpenMSX is the better choice there let me know.

As for App Store distribution, I believe the main issue is that iTunes doesn't allow more than 5 copies of the app per account and that goes against the GPL. I'd need a license exemption from the BlueMSX or OpenMSX devs for this first. This isn't a problem with Cydia, the Android Market, and HP's App Catalog so releasing it as 100% GPL is fine there.

Good to see you signed up : )

I wonder if anyone knows if BlueMSX dev's are willing to give a license exemption? And on what terms.

Cool as hell! Thumbs up for the initiative.

Just one thing: please do not include ROM games without the permission of them authors. Freeware does not imply freely-distributable, so I strongly recommend that, if you plan to bundle the emulator with some games, ask them authors for them explicit permission. For example, I am also planning to distribute our games via the AppStore, so I probably won't give permisson for a 3rd party to release them. So, before trouble: ask first!

For the rest, is just great to have this kind of initiative. Count me in as one future happy buyer/downloader of the product!

Why not just ask them? :-) Oh, and personally, I'd opt for OpenMSX too. (and since those guys are active here.. might be easier to convince them ;-))

Seems Rakashazi has some more work to do : )

Good to hear people are enthousiastic about the project.

I asked you that on other topic and you never responded... Smile
You'll recreate the games in Objective C and OpenGL ES, or, will port an emulator to run the games on it?

Personally I would prefer remakes with retina graphics...
And, please, don't make them over 0.99 cents! That's where the money is.

Great news indeed. First let me say that choosing blueMSX is probably a pretty good idea. Its functionally equivalent with openMSX but its much easier to do custom ports because it doesn't have dependencies on e.g. SDL. The UI is fully in control of the developer to meet the target device look and feel. Although OpenMSX support some of the on screen stuff, its not necessarily desired to use those features in a port. Often you want to customize the interface, use an existing framework and just have a fairly low level interface to the core emulation. An example is the Wii port, which didn't keep anything of the Windows UI and just used the raw frame buffer interface. They btw added some enhancements in the frame buffering allowing for better porting which I brought back into the main source tree.

As far as licensing goes, I don't have any problems giving license exceptions, just contact me.

@dvik
are you going to fix the bugs in the emuulation of the vdp command engine?

Things has been quite busy last year and I haven't had much time to work on MSX projects, but I haven't forgotten about your bug report. I absolutely hope I can find time to fix the issue. I haven't checked the openMSX tree lately, but were they able to resolve the problems?
