PSP Genesis v0.1 - New genesis emulator with sound

The best Genesis Emulator for the PSP just got a great update, heres what <a href="http://www.dcemu.co.uk/vbulletin/showthread.php?t=6889&page=21&pp=10" target="_blank" >Sougen</a> posted on our forums:

<BLOCKQUOTE>I have put up a new release of PSPGenesis. This is more of a test to see if people still get the random hangs. I've play tested the emulator for a few hours without any hangs so it looks like that bug is possibly fixed now.

The main changes in this version are:

- Fixed random hangs (hopefully!)
- switched to pspsdk
- Save state support
- Preliminary (unoptimized) Screen Scaling
- (Really ugly) preliminary source release

Currently you can only save/load to one game slot because I don't have an in-game ui, but this will be resolved soon when I rewrite the ui. Please see the readme for the in-game controls for saving/loading and screen scaling (Yes, I know it is a bit fiddly to use at the moment )

The main things on my list of todo's currently are
- 6 button support
- zip files
- ingame ui
- display optimisation
- game compatibility fixes
- emulator optimisation

In regards to the source code, you will HAVE TO read the README.TXT file just so you understand why the source was released in such a messy state as the password for the source code is in that file.</BLOCKQUOTE>

You can download the release and source code either from the Officail Release Thread <a href="http://www.dcemu.co.uk/vbulletin/showthread.php?t=6889&page=21&pp=10" target="_blank" >Here</a> or our PSP Genesis Page Here --> http://psp-news.dcemu.co.uk/pspgenesis.shtml

Thanks to Sougen for a great new release :)

Hi thanks for the release, ill do a test now :)

Mirror page at PSP Emulation News here --> http://psp-news.dcemu.co.uk/pspgenesis.shtml

does it have full screen, whats the fps like?

bloody hell its impressive, get trying now :)

Heres some great screenshots :)

What a bloody polished release :)

I have to applaud your efforts. I tried it on my psp and my gf's and it works well on both, mine is 1.0 hers is 1.5.

I recommend this if you want the sound, it runs very damn well.


EDIT:
Ah, forget the problem, I accidently took out the .fnt file.... ^^;
Just added it back in and now I can see it on hers too.

The sound is very damn good for a first release, to be honest this doens't feel like a .1 it's more like a .7


If you guys want sound on genesis emulators, try this, it's great...

yeah its awesome to see releases come out of knowhere :)

I can't get it to work on my 1.5 cause i can't find the data.psp :confused:

EDIT: Nevermind :rolleyes:

make sure you also upload the included system.fnt

All I can say is WOW! What a release for a 0.1.....at this rate 0.2 should be complete 100% perfect emulation :) Mad props to you Sougen and feel free to post updates to this whenever you want, we wont mind =)

Is this where we should post a buglist or do you have somewhere we could send bug reports? Also, is this emu running in PAL mode or NTSC? I'm assuming PAL because a rom I tried says that it wont run because it only supports NTSC....... <--- UPDATE......I think i figured this out sorry...use the left and right triggers to switch between countries....USA seems to be NTSC... this really is a nice 1st release :)

yeah all bugs and credits please post here as well as compatibility too :)

Gunstar Heroes runs at full speed. :D

Two hacked Sonic games I've tried lock up, though. (Sonic Gaiden and Metal Sonic)

[ Edited because it was not broken :) ]

Sonic 3 just shuts off the psp.......weird

It doesn't run sonic 3 = but it does run Sonic 3 and Knuckles so who cares :)

Also, is there plans for .grx creation so games such as sonic 3 and knuckles will save like they do on the megadrive?

Excellent first release, very impressive work my good man!

Only issues Ive had are a few US titles that dont work(Sonic among others). Get the Region Error screen with Auto set, and if I go back & set US region is goes black & eventually shuts down the psp.
But all titles I tested from EU/WORLD works excellent, lines is by far the best, trying the other option there only fawked up the screen.
I can come with a more extensive bug-report if needed, but so far.. holy shit man, excellent start!

EDIT:

After Burner (U) - works
Ayrton Sennas Super Monaco GP (U) - works
California Games (U) - Works
Ecco (U) - Works
Jungle Book, The (E) - only works when region set
Lemmings (E) - works
Marble Madness (U) - works
Sonic the Hedgehog 3 (U) & (E) - no worky regardless of region setting, black screen & shutdown
Indiana Jones and the last Crusade (JE) - works
Frogger (UJ) works
Lawnmover Man (JUE) work, but fawked up gfx
Paperboy 1 & 2 (JUE) works
Sonic the Hedgehog 2 (JUE) works
Wonderboy III (JUE) works
Super Hang-On (JUE) (REV01) works, although a tad slow in respons(might be the game itself..)
Rambo III (JUE) (REV01) works
Tetris (JU) works
Turbo Outrun (JUE) works
Outrun (JU) works
Lotus Turbo Challenge (UE) works
Lotus 2 RECS (EUJ) works

ok, im hungover and bored, but I think I'll stick to non working from now on.. much impressed by this port!

Bugs bunny in double trouble (U) -- region must be set & a tad better with cell.. but still fawked gfx(jumps & left/right shake in picture)

This may sound retarded but i got the emulator to appear on the PSP and all but how do i get my roms to work?

I can't get this to run on 1.5. I split eboot for 1.5 swap. What MS do I put system.fnt on? I tried both.

use method B.. and fnt on the card that hold the actual emu.... ms2

i cant find the roms on my 1.5 has anybody got it to work on 1.5 ok i unzipped the files it now works how do you make it full screen cant figure that out

tbh i dont think id risk using this emulator because it overclocks the PSP so it could damage it ... great work tho !!!

This is awesome. Thanks and well done!

There is one thing thats been bugging me about all these geesis emus is the lack of support for 6 button pads but thats just me being picky because most of my favourite games are fighters that work better with the 6 button pad

Aladdin
MK
MK II
MK 3
UMK 3
Virtua Fighter 2


can be added to the working list!

WOW! i signed up to this forum just to tell you how talented you are and how excited i am the EMU can run this good on your first build. do you have plans on working on the snes emu? that would be sweet. i notice i had too unzip my roms on this version (for people who cant access there roms). snes please.

Method A will not work with this emulator unless you have version .2 of mswaptool. I hope that helps! I also have the .fnt file on my main card only, not the boot card.

So far I have tested:
Phantasy Star 4 - NOT WORKING (crashes when I try to hit start during the intro)
Shining Force - WORKING
Shining Force 2 - WORKING

This emulator doesn't overclock the PSP, it simply runs it uncapped...

All this means is (as the processor was built to run at 333 MHz) it provides a better overall performance, and the PSP gets a bit hotter- little to no risk of overheating, though.

Overclocking would be having the processor run at, say, 366 MHz or 400 MHz.

O
M
G

WOW really really nice

Yu Yu Hakusho - Makyoutohissen (J) [h1].bin Works ok few compatibility issues

Yu Yu Hakusho Gaiden - Makyo Issen (J).bin same

If I am not mistaking the only reason why the psp has a cap on it's processor speed is to increase it's battery life.I stand to be corrected if I am wrong.

This hard-froze my PSP on Ecco rom. I had it loaded for about a minute then the entire thing just froze up. Ussually the PSP shuts itself off in that case, but not this time. I had to remove the battery from the back of the system to fix it.

crashed halfway through first race in roadrash 2. Very good emu though. I eagerly look forward to the next update. :D

I don't know who was the first to say it "overclocks" the PSP, but if you read up on the specs of the PSP You would know it is not overclocking at all. Several upcoming PSP titles will be utilizing the full 333mhz potential, and we are just using it early. The PSP was set to 222 because too many people were complaining about battery life, and 222mhz cuts down the drain on battery.

Let me just say this, me and a whole lot of other people have been running the emus at 333mhz for many days now and not a single person has reported anything bad happen to their psp...it does not even get warmer to the hand. If you want your PSP to get warm turn on the WiFi switch and use that for about an hour then you'll have a nice toasty handwarmer :)

Please move "settings menu" to L button.
Add VSYNC option for smooth scrolling.
Add 1.5 screen option and 2X (FIT), (SCANLINES), ETC...
Also add FPS display option.

Super job, thanks!!!!!


Also, some screen corruption occurs right when selecting save game in Landstalker.

The author knows what to add to make it better so it's best not to just tell him to do it.....the only thing we should be doing now is posting bug reports for this version.

If you load an unsupported rom, say, Sonic 2 and Knuckles, you get a black screen... And after you load an unsupported rom (unsuccessfully) you can't play any other roms; They'll just give the same black screen. If you try to start a rom 3 or 4 times, you'll get a black screen that you can't exit out of, and the PSP auto-shuts off after about 10-15 seconds.

Thanks for all the help testing everyone.

To address the concerns of people running the emulator at 333Mhz,
I've updated the emulator so that it now defaults to 222Mhz and you have to manually toggle it to 333Mhz if you so desire.

I'm not sure what the procedure to upload updates is, but I've attached it to this reply.

Nice one! Im one of those that aint concerned about using the cpu at 333Mhz, been running that one all the emus that support it since the 1.50 sploit came out. No issues to speak about. For the record, this update is solely adressing the cpu speed?

Mentioned this in my earlier post, but that auto region I cant find a red line in when it fails. Had it happen on both U & E roms. And sometimes it helps to set region, other times it just get the "BSOD"(black screen of death) upon load. World roms has been perty much flawless so far. Again, very nice work!

This emu is amazing! good job keep up the great work!

Er, both are the same thing. They are just different ways of getting the results. So I'm not sure what using method B would do.

This emulator is great!
I do think that the emulator menu button should be moved, or make a way to continue a game when you go to the menu. I accidentaly hit select a few times, losing my progress in the game.
Also, putting the system in standby doesn't seem to work for me in this emulator. The power light just blinks rapidly until I hold the power switch up for about 10 seconds.
Other stuff like save states will come in time. The above two are really the only concerns I have (especially the standby problem.)

Thanks for the great emulator again!

I tried using the MSSWAP method to get this to work on my PSP v1.5 but the only thing I see is a red gradiant screen with a line at the top, can someone please post a walkthrough for what to do to get this to work with the swap trick? I would really appreciate it! (Also, do you rename your rom to ROM.BIN?)

-Thanks!

Besides that fact that it makes it work.
