openMSX port for Android

I don't know about that, but it's very easy to install: click on the link and Android will download it. Then go to downloads and tap the file and it will be installed. It will ask you whether it is OK to install non-store apps though.

To uninstall openMSX: press and hold the icon in the app manager for a few seconds and then drag and drop it to the trashcan. At least, that is how it is done on a samsung galaxy nexus with stock android 4.x. This will uninstall openMSX and remove the configuration settings from the splash-menu.

Though, the folder <sdcard>/openMSX with all system roms and the openmsx preferences will be retained. You will have to manually delete it if you want to completely get rid of all traces.

We plan to eventually put the stable release of openMSX in google play, under my publisher account (xelasoft) so that anybody can choose between running either the stable official release from google play or running the latest build from the fixato build server. The above mentioned behaviour will be the same when you install from google play. It is intentional behaviour so that you can uninstall and re-install openMSX without loosing all system roms and your openmsx preferences.

As we're preparing for a release, please give us your final comments on the developer builds. Then we can take the along!

Thanks for your feedback. Some reactions:
1) This is a known issue indeed.
2) What exactly do you mean with tablet-keyboard and emulated one?
3) The file browser remembers the last used directories and has short cuts to the sdcard's share/software directory
4) We half-implemented touch scrolling. It kind of works, but it's not completely like how you would expect. Try a bit!
5) automatic screenshots? Who should make them and when?
6) a known issue indeed. We'll enable it some time in the future.
7) you can change the theme in the SDL setup, perhaps the others are clearer for you?
8) Why do you need a Catapult? Almost everything can be done with the built in menu... Try the menu key! Some people even prefer it on PC I don't know what OELSHA is working on, but I don't think a separate GUI is very comfortable on a phone or tablet.

Thanks again for your feedback and enjoy openMSX!

2) the OSD keyboard has a hold function, which makes it possible to hold down SHIFT for example, while pressing another key. This can be activated with the 2nd mouse button on a desktop PC. But I think we forgot to manage this correctly for touch screens I'll make a ticket for this new issue.
3) Just put the system roms in the systemroms folder, its location is explained here: http://openmsx.sourceforge.net/manual/setup.html#installrom - if you insist you can also assign any other folder as system rom folder, but you will need to use the openMSX console to set that up, see: http://openmsx.sourceforge.net/manual/commands.html#filepool
I suggest to just use the default pool.
5) Ah, that's nice indeed, so when quitting openMSX, save the state automatically? Note that you can already save states manually and browse them with screenshot in the "Load state" menu option from the main menu.
