Firefox comes up with an T2K port based Jaguar emulator for the GP2x.

Author release notes:

As a few of you may know, I started work on a GP2X port of the T2K Jaguar emulator quite some time ago.

In the last week or so I’ve managed to scrape some time together to do some more to it, and now it runs well enough that I feel the time’s right to release a work in progress demo version.

There’s still no sound, and there are a few bugs that need ironing out. The GP2X version is based on an early copy of the emulator code that is only complete enough to run Tempest 2000 and the VLM (CD BIOS). I’m planning to upgrade the GP2X version to the latest codebase which successfully runs more ROMs, though.
