PicoDrive -- SEGA Genesis & SEGA CD Emulator Released Updated

Submitted by greg; November 18, 2007

Update: Version 1.35a has been released. The quoted paragraph below details the changes...

Well that test-a-bios-and-you-are-screwed bug was quite a serious one, so I've done an update: fixed a bug which prevented to load any ROMs after testing the BIOS. fixed incorrect CZ80 memory map setup, which caused Z80 crashes and graphics corruption in EU Mega CD model1 BIOS menus. added additional "set to 4:3 scaled" display option for convenience. added an option to disable frame limitter (works only with non-auto frameskip).

Something new to occupy a megabyte or two on your memory stick -- PicoDrive! The readme details everything you must know about Notaz' latest SEGA Genesis / Mega CD emulator. Still requires a bit of work, but works well no less.

This is yet another Megadrive / Genesis emulator for PSP, but with Sega CD / Mega CD support. Although it has been originally written having ARM CPU based devices in mind, it has now been ported to PSP too, by replacing ARM specific parts with portable C code. The base code originates from Dave's (fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville's Gens.

you really dont know just how difficult saturn emulation is, do you? i mean hell, pcsx2 has lower requirements than the best saturn emulator last i checked. not only that but the saturn was absolutly THE WORST system from a hardware standpoint. a horrid bitch to program for even, why so many devs left the system high and dry and went to work on making games for the playstation instead, easier to program for. emulating it on the psp IS impossible, the xbox cant even emulate it so why do you think the psp will be able to?

# L 2007-11-18 21:05

All I can tell on the WHERE can get games, is use google. But, this emulator, while it does need SOME work, runs AMAZINGLY well.

# Agro 2007-11-18 21:06

I'm guessing this won't work 100% on a PSP slim w/ hacked FW, since it can't run the 1.50 home brew?

# gregerson316 2007-11-18 21:32

Dont ask for roms or iso's here.

# Dipstick 2007-11-18 22:03

First post to call you a DumbAss!!! boooya!!!!

# lagunareturns 2007-11-18 22:39

# Hitmanthe3rd 2007-11-18 23:20

STFU and GTFO

Need less of you flame-tards here.

# Paddy 2007-11-19 09:43

i try'd some megadrive roms on picodrive and wow ,they all run super smooth and all the games that didnt work on gens work fine like EA sports titles and dragons fury ,also i have/used all sega emulators for pc and i have never saw once an emulator boot (virtua racing) megadrive version as its not supported and no one has ever emulated it as its hardware is unknown yet picodrive boots it and you can see menus and here music.

superb emulator for psp,32x emulation would only be nice for mabe 2 or 3 games so its really not a big deal,while segacd has many top games.

# Paddy 2007-11-19 09:52

if anyone is having probs getting iso's to work read this ..

when you have segacd iso it should have audio files,between 5 or 50 of them,the audio files should be in mp3 format.

the name convention of both iso and mp3 is important but the titles/names can be what ever you like example ..

iso sonic cd
can be named sonic.iso or abcd.iso

but the mp3 should be named the same in regards to the iso like this ...

sonic.iso
sonic_02.mp3
sonic_03.mp3

or
abcd.iso
abcd_02.mp3
abcd_03.mp3

it doesnt matter what you call the game/iso as long as the mp3's follow the same name.
track 01 is always the iso so your audio always starts at track 02.

hope this helps

# bambam 2007-11-19 10:16

need less of your lame ass comments. just here commenting on the emulator and i get screwed for it.
wtf?

# kato 2007-11-19 10:23

# bambam 2007-11-19 11:15

they go in the same place as the eboot(main folder). just make sure the bios is named correctly or it wont recognize it.

# Ferretboy007 2007-11-19 12:27

What does the bios have to be named?

# Ferretboy007 2007-11-19 13:05

Bloody AWSOME! Great news for us in the UK!
Sonic CD possible at 100%ish on this emu at all per chance? gonna give it a try - dam great work!..Any chance of support for the 32x in the near future??.. I really think that knuckles chaotix and space harrier would top off the immence PSP gaming experiance =]

yet again bloody welldone to you all!

# Hitmanthe3rd 2007-11-19 18:11

OK so I cant run sonic. IDK what the hell im suppose to name what? Where are the iso and bio files what do they look like ???

# NoOne 2007-11-19 18:36

You cannot emulate Sega Saturn is real time or even close to it on the PSP. The 333mhz MIPS cpu isn't capable of emulating the Sega Saturn's multiple CPUs and VDPs in real time or anywhere close to it.

Just consider how demanding PC emulators of Sega Saturn are and how inferior the PSP is to such a PC. Either way, no amount of fanboyism or dick sucking of an emulator author will get you Sega Saturn emulation with a good framerate.

# sj7(super_Jedi7 2007-11-19 18:42

yessss I know this site that has sonic cd roms to...think education+emuat ion...if you added those two words togthor and put .com thats a good site....cant help you more than that dont want to get in trobule...but that site has a working sonic cd (J) and (u) roms....gona try it later my self...

# KahnArtizt 2007-11-19 19:08

Do the Lunar games work on this? Anyone tried?

# mannufld 2007-11-19 19:47

Lunar Eternal works great! The emulator works better on PSP as on GP32x

# Fernando 2007-11-19 19:49

# keyblade 2007-11-20 00:05

I can't seem to get the EMULATOR to recognize the BIOS. Can someone shine some light on the subject please!

# DepheCt 2007-11-20 01:01

Worked flawless on reading the bios, game, etc. Tried to load Mortal Kombat and after the intro it freeze's, skipping the intro makes it freeze :(. Trying sonic now.

# KahnArtizt 2007-11-20 03:10

cant get lunar Star Story to work... anyone else having this problem?

# Paddy 2007-11-20 07:04

anyone having problems running some segacd games needs to enable (megacd options) (better sync) this option is needed for some games that have fmv in the intro or through out the game,you can enable it to get past the intro then disable it when playin the game as it does slow down the emulator.

there is a a fix to the above,once (better sync) is enabled you can then disable (emulate z80) from within (advanced options) this will speed everything back up enabling fmv games like road avenger and cobra command to run much faster,tho if you do this you will need to set the renderer to (fast) and also frame skip to (2).

# Paddy 2007-11-20 11:04

compatibility for segacd
---------------------------
sonic cd - snatcher - road avenger
cobra command - shining force cd
heart of alien - dracula unleashed
dungeon explorer - ecco the dolphin cd
final fight cd - keio flying squadron
lunar- mad dog mcree - mortal kombat cd
prince of persia - rise of the dragon
robo aleste - sol feace - thunder strike
time gal- soul star

all working fine tho some games need different setting to boot or to run at a good frame rate.

im testing another 20 segacd games the nite

# seanus 2007-11-20 13:10

Hey =]
you naming the BIOS right? just rename them with these =]
US: us_scd1_9210.bin EU: eu_mcd1_9210.bin
JP: jp_mcd1_9112.bin

Hope this is of some sort of help =]

I have a mega cd (segacd to you :) so i dont need the sega cd support :)

# keyblade 2007-11-21 02:56

Thanx, but it still won't recognize them. They go right next to the e-boot, right? or in a different folder?

# keyblade 2007-11-21 03:23

I still can't get the emulator to recognize the BIOS even after I re-named them! They go right next to the E-Boot... right? or do they go in a different folder? ...so sad...

# keyblade 2007-11-21 04:21

SWEEEEET!!! I got it!! All I did was removed the .bin from the bios files! and PRESTO!

# Manabyte 2007-11-22 16:17

I'm having problems with the audio and my game wont play. It's in iso/mp3 format. I have it renames as DarkWizard.iso DarkWizard_02.mp3 DarkWizard_03.mp3 Darkwizard_04.mp3 etc... The iso loads, but then I get an error that the mp3 files aren't in the right format, that they should be 44100K. They already ARE. I've messed around with every combination of CDDA and PCM off/on config, and the mp3 files still won't load. I'm really frustrated. HELP!!!

# Manabyte 2007-11-22 16:21

I can't get my game loaded! I'm using iso/mp3 format. They're properly named DarkWizard.iso DarkWizard_02 DarkWizard_03 DarkWizard_04 etc. The iso loads, but I get an error when it gets to the mp3's. It says "Wrong format, must be 44,100". The thing is, they already ARE! I've verified this with Nero media player and Winamp. I've tried mesing around with the CDDA/PCM settings, using every combo there is, and the mp3's still won't load. Someone HELP!!!

# Paddy 2007-11-22 18:33

Problems with sound ...

use program called (Media coder google it)

Just open it, set the 'LAME MP3' tab on the right to CBR, Stereo and somewhere from 96-128Kbps, go to the 'audio' tab on the left and set resample to 44100, set the output folder up top, hit 'add', choose all the mp3s, hit start and wait.

i got this information else where and had to sort some of my own mp3s out for segacd isos and this method works great.

# Paddy 2007-11-22 18:51

detonator orgun - puggsy cd - f1 circus - bc racers - slipheed - starblade - jaguar racer - battle fantasy -space adventure cobra - road rash cd - ecco the dolphin 2 - popfull mail - lunar 2 - sonic cd (us) afterburner 3 - battlecorps - flashback cd -

all working so far but roadrash seems very slow unless frameskip is on and also needs the sync fix
anyone playing sonic cd should use the usa iso as it runs much smoother than the pal 50 uk iso,if you dont like the us music just change it with uk music.

# Paddy 2007-11-22 19:19

i love this emu but i would love to see a few added options but i hate to ask ...

1,set frame rate to adjust (ability to set to 50 or 60 fps not dependant on bios.
2,scanline (makes fmv games and intros look much better.
3,overclock volume (i find this emu very quiet)
4,include more button setups to (better sync) can be mapped to a button (needed mostly for intros)

i really cant think of anything else this emu needs, its superb.

# Bozza 2007-11-24 06:56

Guys love the fact that there is no a mega cd emu and saturn emu, can someone point me in the direction of how to transfer my original mega cd games on to psp and also it will not detect my mega cd bios, i have tried 3 different ones and putting them in teh correct folder, ANY help would be welcomed, cheers

# Paddy 2007-11-26 09:20

bios files dont go in a folder, they should be in the main emu directory folder along with the emu eboot, bios files should also be named correctly.

you can use nero burning rom or any other program that lets you create an iso of a cd or dvd disc,but in the case of megacd and also sega saturn you should create an iso and also rip out the in game audio,nero does this nicely and i sugest you use nero.

in nero options ,choose nero burning rom,not nero express or smartstart,once the window has opened click on EXTRAS at top and choose SAVE TRACKS ,make sure your game disc is in the drive and it should load up showing you track 1 iso and then track 2 and track 3 and so on.

from here you can rip the iso file and the audio,you can rip the iso as nrg (nero iso format)
but you shouldnt choose nrg ,you want raw iso and for the audio tracks choose mp3.

once you highlight your iso or music track choose
the file type format to convert to,this is done through the output file format tab in the middle of the window,so if you have the iso highlighted you will be able to change the output format to iso or nrg,same with audio,mp3 or wav or whatever .

# Paddy 2007-11-26 09:31

once you have ripped your game disc ,you should have 1 iso and several mp3 tracks,they should all go in a folder together and should also be named in a cetain way.

the iso should always be track 01 ,but it can be called what ever you like ,soniccd_01.iso
(( _01.iso )) is the important part and the audio mp3s should follow the same name.

soniccd_01.iso

the mp3 tracks should be named the same

soniccd_02.mp3
soniccd_03.mp3
and so on ....

when you have ripped your gamedisc ,iso and mp3 tracks ,nero will have numbered them for you, you should keep them in that order as thats the correct order the tracks play on the original disc,so you only need to rename your iso and mp3 tracks slightly but keep the track numbers.

this method is the exact same with sega saturn games and this is how pc emulators run megacd and saturn games.

when I try to load cobra command, it freezes at the end of the sega intro. I've had this problem before but don't remember exactly what I did to fix it, Iremember it had something to do with formatting the sega cd ram.

If you're still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you'll know which is right for you.

What is it about %blogtitle% that has everyone "up in arms"? Sometimes it may take a trial and error to be able to copy a video or movie and make it play smoothly on your DVD player. CD burning may be a little simpler but when it comes to DVD burning, which allows a large capacity of files to be stored, you may need to have other tools and software.
