This emulator is AWESOME and it runs lots of Sega CD games great! I love Sega CD xD
Only having trouble with two games:
Dune
Wheel of Fortune (this version of wheel of fortune is remarkably cheesy and awesome imho)

Regarding the problem brought up back in this post: http://www.dcemu.co.uk/vbulletin/sho...1&postcount=34 (regarding PicoDrive being unable to open ROMs in certain folders), I 've been able to recreate this problem. I don't know how TheGrandPubaa encountered it, but on my own PSP it happened after I copied the folder containing my MegaDrive ROMs to another folder. Before I moved the ROMs folder, PicoDrive recognized it just fine. Afterwards it wouldn't even open the folder. Here's the kicker though: I tried moving the ROMs for all of my emulators to the same folder and the ONLY emulator that was able to open the post-moved folders was gpSP. All of the other emulators failed to recoginize the folders after they were moved.
So, if TheGrandPubaa's problem was the same as mine, it looks like this isn't a problem specific to PicoDrive, but rather a common problem in PSP emulator file-browsing code. I don't know what gpSP is doing differently, but it seems to be immune to the problem.
I've downgraded to 1.5 and can confirm this is a bug in the emu. Expect another bugfix release soon.Quote:

I just noticed that going into sleep mode hard resets the psp, so save before you shut down
Hmm, doesn't happen for me, which firmware do you use?Quote:

Try enabling "better sync" (sega CD options) sometime before that spot (not after it happens as it may be too late).Quote:

Hey Notaz . thanks again for this awesome emulator :)
In the next release, is there any chance of preview pics/boxart support in the next release? (they would display next to rom name on the left)
Like the way daedalus has them for instance.
Either way, thanks for all your hard work :)
Yeah, I have the same problem with Sleep mode, but it only happens when you wait a few minutes it seems. If you put into sleep mode, then get right out of it it comes back on fine. If you wait a few minutes or more when you "wake" it you get a shut off... I was pretty far into Final Fight CD when I noticed it :( .. Small price to pay for an amazing piece of emulation code!
I'm using an original PSP running firmware 3.71 M33-3 by the way.
Also, I couldn't get either disc of Prize Fighter to boot. I got them from romulation. Going to try another source.
Any chance of getting a Rewind option for PicoDrive? That would make it 10% cooler bring the total coolness to 110%! :P
Slightly off-topic but, Is there any way to get a custom firmware onto a psp slim that is already at level 3.71? I've tried to get it but every thing I've seen about it says you must already have a custom fimware of a lower level. Thanks.
Yeah 3.71. I found that it happens with gpsp too. I guess I should update.Quote:

Just wondering if we can expect any future upgrades to this great emulator. I am still pushing for a rewind option. Once you try it it's hard to go back to the old save/load state option.
Thanks again for an amazing piece of code. Maybe you can take a look at SnesTYL and speed the DSP games up a tad :P

OK, maybe 5FPS below full.
Anyway, I definately think frameskip 1 looks better on the PSP screen because it prevents ghosting (60FPS is too much to ask of it).
Besides, the good GP2X SNES emulators probably have some ARM assembly code to speed up parts of them that could not be reused on the PSP (because it's MIPS).
You aren't trying very hard then, most games that don't use special chipsets run at 60 fps/0 frameskip unless they're using lots of mode 7 effects, assuming that you're using the right settings. Maybe some games drop a few frames if there's lots of sprites on screen or something but that happens pretty rarely, pretty much every game runs with a median framerate of 60.Quote:

Notaz, sorry for this OT... But is possible this option also on picodrive? Unfortunately the gamma adjustment doesn't reduced the ghosting effect.:(
I have nothing to do with snesTYL besides reading the source :P Never really worked on it nor have the urge to.
That doesn't sound too hard to do though, if someone's up to it.
Tinnus: While you're not working on SnesTYL can you also add a rewind/ffward/mirror function? :P
There is nothing fancy about this emulator (no dynarecs/asm cores), but it's still able to run many Genesis games fullspeed with no frameskip (including some CD ones), and others with some skipping. However there are some CD games which won't run too well (although situation can be improved by tweaking some options). This emulator uses hardware MP3 decoding via audiocodec library in PSP.
Could someone explain to me what dynarecs/asm cores are?
Disclaimer: I am not a game programmer, and know very little other than the basic theory behind these things. Feel free to correct me ppl.
animekid4:
In very basic terms, an emulator can either employ a interpreter core or an interpreter+Dynarec (dynamic recompiler). A dynarec can make the emulation faster basically, so is useful for emulating more powerful hardware using the limited PSP hardware.
An interpreter takes the game data meant for the original machine (megadrive in this case) one executed action at a time, and translates it into code that will run on the host platform (PSP).
A Dynarec can look at a larger block of code, and possibly turn it into a chunk of code that is more optimised for the PSP hardware than simply translating each action of the original Megadrive hardware 1 by 1 would acheive.
ASM means assembly language.
Most programs are written in what's known as a 'higher level' language like C, and then put through whats known as a compiler. The compiler takes generic statements like 'If A is bigger than B, take this action.....' and turns it into the exact actions that the CPU/other hardware must do to make that happen.
This makes it easier to program, and also makes the code easier to port between systems.
Writing code in assembly language is like controlling the inner-workings of the hardware directly. By doing this it is often possible to write code that is more optimised for that particular hardware than a compiler may produce. It requires a great deal of knowledge of the target hardware to write something useful in assembly, and a good compiler may often create code just as optimised as less-than-brilliant assembly, so it is reserved mostly for when there really is a strong need for a speedup of certain parts of a program.
Found that this emu does not play some games as smooth as dgen...the prob im having with dgen since updating to 3.71 is that even with hide corrupt icons enabled i still get the corrupt icon ! ive tried renaming and a few icon hiding programs but nothing works ,Anyone else have this prob?
This is most annoying:P
Which games do you think run smoother in D-Gen? I haven't run into any games that don't run smoothly (rom) and many Sega-CD's run great as well.Quote:

Is there any way to change my DGEN save files to a format that compatible with Picodrive?
just play through em again - its what playing old systems are all about - fun.
i might add for those running the games with 44k sound - the original system only used 22k so thats a bit of a waste of power - all my games run fine (some if you adjust timing settings) but i have absolutly no speed problems at all.
w000t NP I got it to work bad .ISOS w0000t Shining Force CD omfg ! time for Final Fight ! wicked emulator !!!! by the way I know it supports Game Genie, but does anyone know if Action Replay is supported or will be supported in the future ?
now all we need is a 32X emu.
..or for 32x support for PSP's Picodrive emu. Notaz knows that 32x support would be easy to add but doesn't feel like it is worth it due to very little games were interesting on it. Most 32x games that came out were ports of genesis games or Sega CD games. There were a few originals like Knuckles Choatix but the demand of the support and knowing that there were very few 32x games warrants Notaz the thinking that it is not important. These are just my thoughts and I'm sure Notaz has his reasons why 32x support isn't on his to do list. I just want 32x support so I can play all my SONIC CLASSICS on the go!Quote:

I hope he implements 32x support, if I remember correctly After Burner II was a perfect port of the arcade. And there were other cool games on the 32x, it just wern't that many.
i couldnt care less about 32X.. it would be better if notaz helped pspuae out! =)
That would be nice but already Chilly Willy has recently joined the PSPUAE team and they are all currently working on the next release.:thumbup:Quote:

However i only play 2 sega cd games as well. Sonic cd And Lunar(Sega cd version of lunar saves a lot of space then using the psx eboot)
32x is the only emulator left to be made for the psp right?(Not including systems Saturn and up which the psp wouldn't be able to run anyway.)
Anyway this is a great emulator. I work at gamecrazy. People go crazy when they see me playing sonic cd. LOL.
Great work dude!
Me back to play some more snatcher!!!!
I just downloaded this, but I can't get it to work. Whenever I try to boot up the emulator, I get:
"The game could not be started.(80020148)" Is it because I'm using the PSP Slim (version 3.60) or am I doing something wrong? Help plz.=(
