@@2. "ReadAhead buffer"
|

#ifdef GP2X
|
||||
This option is for dealing with slow SD card access in GP2X, which makes FMV
|
||||
games unplayable. It will allow emulator not to access SD card for longer periods
|
||||
of time, but it will take more time to fill the buffer.

#endif
|

#ifdef GIZ
|

This option can prefetch more data from the CD then read by the game - not really
|
||||
useful for Gizmondo (this is a workaround for SD access problems on GP2X port).
|
||||
This option can prefetch more data from the CD image then requested by game

(to avoid accessing card later), what can improve performance in some cases.

wrote ARM recompiler and some HLE code for VR.

wrote ARM recompiler and some HLE code for VR. Credits to Exophase and

Rokas for various ideas.
|

* 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).
|
||||
read when new one is missing).
|
||||
* Fixed a bug where some key combos didn't work as expected.
|
||||
* Fixed a regression in renderer (some graphic glitches in rare cases).
|
||||
* Adjusted fast rernderer to work with more games, including VR.
|
||||
* Adjusted fast renderer to work with more games, including VR.
|
||||
* Fixed a problem where SegaCD RAM cart data was getting lost on reset.
|
||||
* Greatly reduced SegaCD FMV game slowdowns by disabling read-ahead in the
|
||||
Linux kernel and C library (thanks to Rokas and Exophase for ideas again).
|
||||
Be sure to keep "ReadAhead buffer" OFF to avoid slowdowns.
|
||||
+ 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.
|
||||
|
||||
1.35b
|
||||
* PSP: mp3 code should no longer fail on 1.5 firmware.
