PicoDrive for PSP v1.35b - Genesis/Sega CD Emulator for the PSP

**brianon** · January 27th, 2008, 20:20

Hi Guys,

I have a PSP Slim. Dark Alex 3.80 m33-4 fw.

Am having trouble getting PicoDrive 1.35b going.

First off...does this work with the slim ?

If it does...here is what I have...

H:\PSP\GAME\PicoDrive%
H:\PSP\GAME\PicoDrive
In here I have my roms/ISOs & the ciorrect BIOS files.

On PSP PicoDrive shows up but when I run it it gives an error saying "could not be started".

Any ideas ? Any help much appreciated.

Cheers,
Brian.

You need the normal version (with just one folder), not the kxploited one (with two, one normal and one with %).

Thanks for the reply. I actually downloaded what I thouhgt was the non-kxploit version from pspupdates.

Turns out both versions there have the PicoDrive% folder also.

Just downloaded there from DCEmu and it doesn't have the PicoDrive% folder so I will try that one tonight.

Much aprpeciated. Thanks.

Just a quick note of thanks to Tinnus for your help.

PicoDrive working great now

Can't get the two Sega CD games I have working though. NHL 94 and Sensible Soccer.

Both are ISO/MP3/CUE. Both load the little sonic logo and then the screen goes black and stays that way.

Any ideas anyone ? MP3s are referenced correctly in the cue file. The mp3 names are quite long though. Could that be a problem ?

You don't need a .cue file, just the .iso and the mp3s named correctly.

They must be named as the readme tells you:
"
The game must be dumped to ISO format, but BIN can be used too. If you want
CD music, you must use ISO+mp3 files. Audio from BIN files won't be read at
all. Also BIN files are usually larger, so it's better to use ISO. ISO+mp3
files can be named similarly as for other emus.
Here are some examples:

SonicCD.iso data track
SonicCD_02.mp3 audio track 1 (CD track 2)
SonicCD_03.mp3
...

Sonic the Hedgehog CD (US) - Track 01.iso
Sonic the Hedgehog CD (US) - Track 02.mp3
Sonic the Hedgehog CD (US) - Track 03.mp3
...

It is very important to have the MP3s encoded at 44kHz sample rate and they
must be stereo, or else they will play too fast/slow or won't play at all.
Be sure NOT to use anything but classic mp3 format (don't use things like
mp3pro)."

But having them named incorrectly should only make the cd-audio not work, the game should still run.

Also from the readme:
"
Sega/Mega CD: If the game hangs after Sega logo, you may need to enable
"better sync" and/or "Scale/Rot. fx" options, found in "Sega/Mega CD options"
submenu, and then reset the game. Some other games may also require
"CDDA audio" and "PCM audio" to be enabled to work (enabled by default).
Incorrectly named/missing mp3s may also be the cause."

I've only played sonic CD and night trap (and a whole lot of MegaDrive games), both worked great.

Much thanks again. NHL 94 now boots with "better sync". Unplayable though as too slow. Ah well.

Readme is about an apt name as I can possibly think of, I don't understand why people see them but don't think to check there first when they have an issue.

I mean I don't mind copying/pasting that from the file, but it would have been a lot quicker for you to have checked there to find an answer to the issue first.

First off... Thanks for this amazing emulator!

I wanted to report a possible Bug and Sega CD load time variance.

PSP Info: Phat original 1.50 running custom firmware 3.90m33 1.5 kernal v2. Default Game folder set to 3.xx
The Bug: When using the eboot in the Game folder, the HOME button does not work. If I move the eboot to Game150, the HOME button is working.
Its nothing Emulator breaking because you can still exit via the menu, but strange. While testing this, I found something else. It seems Sega CD games load faster from the 3.xx Game folder versus the Game150. On Sonic CD the difference is 15 seconds. Again, nothing ground breaking but wanted to report it.

It could be the Firmware, but Masterboy and PSPDoom 5.0 do not have this issue when moved back and forth.

Oh and Thanks for the windows port running Virtua Racing!
