I'd like to write a game for BBOS but want to know the best program to use. I can use either Windows 7 64-bit or Fedora Linux as my OS.

I don't mind if the program isn't specific to BB as long as it creates J2ME apps.

You won't be able to install it on a BlackBerry phone, as you can no longer get signature keys.

I think these are only needed for some features like Internet access. I've installed unsigned apps before.

My guess is whatever you made Apps with all those years ago... would be what's best to make them with today.

BBOS was very finicky about how it worked with java apps, it's why most developers I knew... used BlackBerry own tools. But it's nothing like today's tools where you can build some games in a few hours using prebuilt engines and graphics.

Lots of BB SDK tools can be found at the links below. But as conite pointed out, you will not be able to install an app on the device unless you have a valid signing key. You will only be able to run it on a simulator.

In case you still want to try I have recently been playing around with several versions of JDE (from 4.0.0 to 7.1.0) and BB simulators on a PC with Windows XP and Windows 7 32-bit and Java SE JDK 6 Update 45 (file jdk-6u45-windows-i586.exe). All BB tools are 32-bit so x86 Java is required even on x64 system. Java jdk-7u80-windows-i586.exe had some problems with earlier versions of JDE but was ok with 4.1.0+. You need to manually configure two system environment variables (JAVA_HOME and PATH) to point to Java JDK's installation directory.

Are you sure I can't install apps with no signing key? I've downloaded unsigned apps from phoneky.com.

Yes.

@conite, if I write a generic J2ME app rather than a specific BB app, can I install it unsigned? If not, why does Phoneky work?

I'm a bit rusty when it comes to development on BBOS. But as far as I remember, you couldn't install an unsigned app - that was part of the security of the device.

Could someone else's existing keys be used to sign a developed app?

Edit: In looking back through a couple of old pieces of information, apparently a couple of csj files from RIM that each developer would get were used with a "BlackBerry BarSigner Tool" to register with a Signing Authority (via the development tool of choice?). Was that back then a RIM Signing Authority (which probably no longer exists) or a separate external Signing Authority? Would just the csj files be needed nowadays or would a developer need to have already earlier completed registration with a RIM signing authority (with those csj files) before BlackBerry shutdown?

[SAVVYSCLUTTER]

@spARTacus, .bar is for BB10, not BBOS. Are you thinking of BB10 for the signing requirement?

[spARTacus]

Sorry, what I had dug into was for Playbook OS and BB10.

No. Keys expire.
