There are no major changes to report with this update; it synchronizes the PSP version with the Marat’s official distribution. There are changes to the VDP (video) code, although I haven’t noticed any differences in rendering or performance.

This is a small update to fix current known issues. Changes in this version:

• A Spectrum joystick button/keyboard key can now be assigned to multiple PSP buttons
• Sticky key status will now be correctly reset when the virtual keyboard is toggled on/off

Download

This update fixes the following issues present in version 0.9.0.2:

• Palette corruption on various PSP units
• Bug in the sound rendering engine that would cause occasional sound slowdowns

Updates from 0.9.0.1 (just to reiterate):

• Added various game image types missing from the initial release
• New virtual keyboard
• Added monitor type selection (color/grayscale)
• Fixed a serious memory leak, which would manifest itself when opening ZIP files
• Fixed the “tape loading hang” bug
• Added +3 support
• Added Kempston joystick support
• Added “hack cursor” support (keyboard up/down/left/right)
• Lots of code reshuffling

New in this version:

• Added various game image types missing from the initial release
• New virtual keyboard
• Added monitor type selection (color/grayscale)
• Fixed a serious memory leak, which would manifest itself when opening ZIP files
• Fixed the “tape loading hang” bug
• Added +3 support
• Added Kempston joystick support
• Added “hack cursor” support (keyboard up/down/left/right)
• Lots of code reshuffling

This version also includes extended DSK support; however, this does not seem to work correctly at the moment. Since the next version of Fuse is going to have drastically revamped 765 support, I’m probably not going to work on this until the next version.

UPDATE At least one user has reported palette corruption problems, so I’m pulling the new version down until I can revert the psplib code back to an older version. Please bear with me, and if you have the version originally released, please don’t distribute it.

Joining the cornucopia of emulators today is a port of the Free Unix Spectrum Emulator (Fuse), a Sinclair Spectrum emulator. A nice addition to the PSP port is support for ZIP files.

I’m happy with most of the port, however, there is an issue with intermittent tape loading hangs that I will be investigating further. To mitigate this issue (and Spectrum’s slow tape loads), I’m (grudgingly, for those of you who remember Caprice32 ) adding support for Z80 files from the game tab. The ‘autoload slot’ feature is also available.

Please check the documentation for any other issues. Feedback is always appreciated!

This is mostly a bugfix release. Here’s what’s new:

• Bugfix - many games, especially MegaROM games did not load correctly in the previous version (thanks Victor)
• Added Fast Forward button mapping - while disabled by default, you can map any button to fast-forward emulation in the Controls menu
• Custom mapper types can now be embedded in source code. This version includes built-in support for Zanac Ex and Mon Mon Monster. Contact me if you’d like to add additional mappings

This version no longer includes a version compiled for firmware 1.50.

Download

New features in this version:

• Games/applications that require MSX Audio/MSX Music will no longer crash the emulator if either is disabled in System settings - there will simply be no Y2413/YM8950 audio
• ROM type settings are now saved between sessions - up to 500 different ROM’s can be tracked by CRC32 value

The second feature requires some experimentation, and I welcome any feedback you may have. As mentioned, the limit is 500 ROM’s - this is not counting the “auto-detect” ROM’s, for obvious reasons. The list is updated when ROM type is changed via the System menu - to remove an entry from the list, simply set ROM type to “auto-detect”.

Searching through the CRC values is done in linear time, when a ROM is actually loaded, but for 500 entries, this is not likely to take long (I’m not sure how long reading/writing these entries will take to memory stick, however).

The list is loaded from stick when the emulator starts up, stored in memory while the emulator runs, and saved back to stick when emulator is exited.

UPDATE Version compiled for firmware 1.50 does not work. Please use the 2.00 version

Mislabeled settings are the reason why FMPAC games failed to run even with MSX Music enabled. Versions up to (but not including) 3.5.2 incorrectly labeled the MSX Audio engine as MSX Music and vice versa.

Version 3.5.2 fixes this issue and is now available for download. Note that if you don’t want to download it (it adds nothing but a correction to the typo), simply reverse your settings for MSX Audio and MSX Music and try running your favorite FMPAC-based games again. Note also that running FMPAC-based games with MSX Music disabled will hang the emulator.

The FMPAC diagnostic cartridge, Aleste 1 and 2 have all been tested and run fine and with sound. Please note, however, that the MSX Music engine requires more CPU power, so you will need to increase the CPU frequency (and disable vertical blanking/vsync) if you want full-framerate MSX goodness.

Special thanks to Victor Sartori for his help in tracking down the issue.

Today’s emulator’s been in works for several months now, and while it’s still not 100% complete (menu system is still incomplete, and no documentation yet available), I figured it’d be best to release it anyway. I’m happy to present (as far as I know) PSP’s first CPS3 emulator.

UPDATE April Fool’s! Hope the prank was not too cruel - if it helps, I’m hoping for a good Capcom Play System III emulator on the PSP myself. While the platform has few good games, the Street Fighter III series alone are worth it

As promised, ColEm has been updated. Here are the changes:

• PSP version brought up to date with the official release (changes are mostly internal)
• Replaced the rendering engine with a more stable one
• When switching games, latest save state will be automatically highlighted
