Emulators for PSP

Name = PSP Genesis (Genesis/Megadrive Emulator for PSP)

Authors /Website = Sougen

Downloads = Here v0.18c 30th July 2005

Just another small update:

- Automatic support for loading old save states (untested since I don't have any old save states around)
- Option to change the sound quality. (44100 is not recommended because it needs a lot of processing power to emulate the ym2612 chip at that frequency), but it's there if you really want it.

Just some info on the 6-button setting. You should only turn it on for games that support it. A lot of games don't handle the 6-button controller properly (which is why there is a 'Mode' button on a real controller that you hold down when you power up the megadrive). I'll have a look at seeing if this can be autodetected.

Just so people won't be guessing/asking later on, I am currently really busy, so there won't be much releases for a while.

Here v0.17 24th July 2005

I've just uploaded the latest version of PSPGenesis. There are a lot of changes in this version, so there may be some unforseen issues, but the major changes are:

- 6 button joystick support
- zip support (using Ruka's unziplib)
- fixed a bug in save states (current saves won't work - if you really,
really want your old save I could consider writing a converter... ).
- user definable controls
- optimized the sound code a bit (more games run faster now).
- games list is now sorted
- implemented new ui
- user skins support for ui
- return to current game support
- frameskip options (note, if you have manual frameskip and the
game cant keep up, the sound will obviously be jumpy if u dont
have auto frameskip on)
- vsync option
- multiple save slots per game
- experimental 50Hz conversion
- added 266Mhz CPU speed setting
- other miscellaneous fixes and features

If you're running a 1.50 psp, make sure you have all the new skin files in the proper directory.

Here v0.16 17th July 2005

Just a small update. I've optimised the display code a little, so you'll notice a speed improvement in all scaling modes now. The emulator should run better than all previous versions.
And JcBoyCool, yeah, the analogue stick and trigger controls is just a temporary measure until a proper ingame ui is written.


Here v0.15 17th July 2005

Sourcecode v0.15 Here 17th July 2005

I have put up a new release of PSPGenesis. This is more of a test to see if people still get the random hangs. I've play tested the emulator for a few hours without any hangs so it looks like that bug is possibly fixed now.

The main changes in this version are:

- Fixed random hangs (hopefully!)
- switched to pspsdk
- Save state support
- Preliminary (unoptimized) Screen Scaling
- (Really ugly) preliminary source release

Currently you can only save/load to one game slot because I don't have an in-game ui, but this will be resolved soon when I rewrite the ui. Please see the readme for the in-game controls for saving/loading and screen scaling (Yes, I know it is a bit fiddly to use at the moment )

The main things on my list of todo's currently are
- 6 button support
- zip files
- ingame ui
- display optimisation
- game compatibility fixes
- emulator optimisation

In regards to the source code, you will HAVE TO read the README.TXT file just so you understand why the source was released in such a messy state as the password for the source code is in that file.
