Basilisk II PSP Port (Mac Emulator for PSP) Test Release 20 20/07/08

July 20th, 2008, 22:20 Posted By: wraggster

Jf has posted yet another release of the Mac Emulator for the PSP, heres the release details:

Okay people, we're really getting down to the nitty-gritty... the goalpost is in sight. I'm tempted to consider this RC1.

Here's test 20. MAJOR changes:

The floating point has been SUBSTANTIALLY rewritten. I've incorporated SoftFloat into the FPU emulation to get extended precision floating point. I've also added most of the FPU functionality that's usually only present in B2 when using x86 assembly. The only compromise left is the transcendental functions are still done in double precision. I seem to have cured most of the FPU problems - the scrollbars in OS8.x work, Arashi and Maelstrom play properly, the calculator gives proper answers... I'd appreciate it if people really checked this as well as they can. This was a BIG rewrite of B2 code (for the FPU). This code should also be portable, so it could help folks trying to port B2 to other platforms as well. Given the rewrite in the FPU and other more minor changes to the B2 code that AREN'T platform specific, I've decided to bump the B2 version from 1.0 to 1.1.

The Mac would hang on RESTART, and I don't feel like chasing that bug down, so I altered B2 to shut down on restart instead of trying to restart. So instead of the PSP hanging and people screaming about that, now they'll just whine about the emulator shutting down instead of restarting.

Fixed some other minor bugs, but spent so much time on the FPU that I don't remember them anymore.

I still haven't heard any feedback on the IR keyboard support. I'd appreciate it.

Download and give feedback and Compatability Reports via comments.
