Zelurker has released 2 very quick updates to the continuation of Yoyofrs original Neogeo CD Emulator for the PSP, heres whats new in both new versions:

<blockquote>Version 0.7.1
Just a fix for a stupid bug which made quite a few games to crash in 0.7.
Thanks to the quick tests which allowed to spot this one very quickly...

Version 0.7
Less bugs, better sound quality, a few little additions, and a loooong list of changes :

- Fixed crash in breakers : this is once again related to the upload area,
so I can just hope it won't break other games
- Try harder to recognise game files from ipl.txt : some originals have
weird filenames in the ipl.txt (a double dragon version is in this case).
Now if I can't find the file type in the extension, I look for it in
the whole filename, which seems to work for this double dragon version,
at least.
- Fixed sound effects : they are now much clearer, and in real stereo.
The difference is especially noticeable in bust a move.
- Fixed a last possible corruption of the memcard.bin file if quiting with
the home key. Now it should be safe to use the home key to quit at any
time, and there should be no way left to corrupt any file (mp3 or other).
If you use fw 2.0, be sure to use the Exit command from the gui though,
or do otherwise at your own risk (I am not testing neocdpsp with fw 2.0)
- The sound effects do not stop anymore after 3 or 4 games (finally !)
- Added some game messages at the bottom of the screen (now you know
when an mp3 track is starting to play, if it didn't find it, if there
was an error decoding it, and so on...)
- In previous version, if an mp3 had some id3 tags it couldn't be played
in neocdpsp. This is fixed now, sorry for those who encountered this
problem.
- Now you can also place your mp3s in PSP/MUSIC. Example :
say you have a game in a directory mslug. The you can put its mp3s
as previously in mslug/neocd.mp3/ but now you can also put them in
/PSP/MUSIC/mslug/ if you prefer. After all these are mp3s, so you should
be able to play them from the psp interface if you want to !
The directory in music where you put the mp3 must be named exactly like
the directory of the game for neocdpsp.
- The mp3 decoder is a little more resistant to crashes, that is if you have
an mp3 file at 0 or 1 byte after you have filled your memory card, it
won't crash anymore. I don't say it will not every crash again though,
there are probably files which can make it crash !
- Fixed sound and music in top players golf
- Fixed Art of Fighting 3 freezing at start of gameplay
- The loading of zipped games is even faster than in 0.6.2 !
- The ingame sound effects of samurai spirits rpg work now, the game is
still very long to load, but it was already long on the original hardware
and is now limited by the access speed of the memory card.
- Now the memory card is writen only when you quit the game, not everytime
the game tries to write to it.
- Added "Select lock" option to the gui. When enabled the controls become:
Select + LTrigger instead of LTrigger for the gui
Select + RTrigger instead of RTrigger for snapshots
and Select + Cross instead of Select alone (pause in most games).
This for those who press the triggers by accident !</blockquote>
