PicoDrive for PSP v1.40b - Genesis/Sega CD Emulator for the PSP

April 6th, 2008, 21:52 Posted By: notaz

This is a bugfix release only, don't expect any speed improvements. It also has a few new features.

SVP emulation is working, but it's unplayable (too slow), because dynarec is not implemented (it needs too much work, and I want to work on something else, again). The dynarec from GP2X version is not suitable, because it's ARM only and non-portable.

Full changelog below:

• Fixed sprite masking code. Thanks to Lordus for explaining how it works.
• Added "disable sprite limit" option.
• Added black level adjustment to display options.
• Changed reset to act as 'soft' reset.
• Added detection for Puggsy (it doesn't really have sram).
• Some small timing adjustments.
• Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing. No recompiler for PSP version though.
• Changed config file format, files are now human-readable. Game specific configs are now held in single file (but old game config files are still read when new one is missing).
• Fixed a bug where some key combos didn't work as expected.
• Adjusted fast renderer to work with more games, including VR.
• Fixed a problem where SegaCD RAM cart data was getting lost on reset.
• PicoDrive now comes with a game config file for some games which need special settings, so they should now work out-of-the-box. More games will be added with later updates.
