DGen Sega Genesis Emulator

[ArnimS]

There are a few casual/slow games (RPGs, Puzzles) for Genesis, so why not build an emulator?

There are plenty to choose from, but only one is portable enough to build in maemo out-of-box, and that's...

http://pupnik.de/dgen.html

It's fully open-source. Give it a shot and post results here. Install from file with app-manager (it2006) or dpkg -i (it2007/bora).

Start it from the terminal with dgen <romname> or create a shortcut with load-applet run or osso-statusbar-cpu applets.

To preempt the obvious questions, no, "gens" isn't going to be ported by me - it uses x86 assembly instructions. "Generator" might work someday, but it's barfing-up make-errors of a strange and mysterious kind.

If it's too slow for you, you're not drinking enough beer.

Cheers!

Someone needs to port PicoDrive, I used to run a port on my 100Mhz Nokia 6600, ran more than quickly enough. It's designed for ARM. GP2X version is perfect in almost every way, inc MegaCD.

ArnimS, when are you going to get around to running your own repository already!?!?!?!?

[yabbas]

Great work arnims. Not yet tried it though, but it's installed and ready to run *cough* "backups" when I get hold of a few.

Yeah that'd probably be the best genesis emu for the 770. I spent about 33 hours hacking at it back in May, 2007 and didn't get a buildable version. So i'm pretty burned out.

Got generator compiled, thanks to a patched version discovered by unique311, but it just yields black screen and there is a build error that might become critical. If anyone is interested, i can put sources up.

And of course i can put the partially-ported picodrive sources up too, if someone is serious about working on it.

The genesis just isn't so high on my list because the fast games would require better dpad and RHS keys. The RPGs for it are not comparable in quality to the SNES imo, so ... anyway...

[yabbas]

Stick the picodrive sources up and I'll see if I ave the time to sort things out.

[DynaMight]

Source to the original is here: http://www.finalburn.com/mobile/source.html

Modified GP2X version is here: http://notaz.gp2x.de/pico.php

It's been ported to many other platforms too.

(edit) I think this would be more worthwhile though...

i started it on xterminal but it says error, any advice?

(nothing personal, just in a sour mood)

You should probably clarify as much as you can.

[osmiley99]

I downloaded the dgen application for my n800, After that I open it in xterminal by typing dgen, the xterminal does recgonize the dgen application, which causes it to pop up on the xterminal. But the thing is I cant do nothing with the dgen, i cant open up files to play the sega roms, its just a black screen that says dgen 1.23. do you know how i can get the dgen application to function like the vgb, ines, and mg emulators on n800?

This emulator is barely functional.

Eventually, perhaps, someone will optimize it, but right now 5fps won't run anything worthwhile.

All of this was explained in this thread and in the links provided.

ArnimS hello i have a emulator nintendo 64, you could improve it here is the link http://rapidshare.com/files/293487705/nintendo_64.rar

Mmh... I think I'm doing something wrong... :)
I download the "boogerman" rom, and put it in a folder called "prova". Then i installed DGEN and write on X Terminal:

dgen boogerman.smd

But the answer was "Couldn't load ROM file boogerman.smd!"

So i try with

dgen boogerman
dgen prova/boogerman.smd
dgen prova/boogerman

But... Nothing. Always the same answer...!
So i thinked the rom wasn't good, and download another rom. This time the rom was a .bin file (i don't know why) and i try with it but... Always nothing.

What can u say me?
I wait for your wisdom answers!! ;)

Ps
Please, forgive my bad english, i'm only a stupid italian guy. :)

try renaming the file from ROMNAME.smd to ROMNAME.gen.

Nothing... Always the same problem... What can i do?

[mas5acre]

just checked my psp files, try ROMNAME.bin

[DarkAlexander]

i already try with a .bin extension... But nothing. :(
Always "Couldn't load ROM file boogerman.bin!"
I try with different rom, but nothing...!! What can i do?
I really want to try this emulator! :)

[HtheB]

which phone are you using?

[DarkAlexander]

Nokia n900!

[HtheB]

please read the first topic date... this wasn't even for the N900...

=_=

[DarkAlexander]

Ops... :)
Sorry! Do u know if exist a Sega Genesis Emulatore on N900?

[HtheB]

there is no one (yet)

I hope someone ports PicoDrive though.

[ArnimS]

being a linux noob, im not really sure what to do with the .gz files. do you install it? or is it for compiling..

also..i implore you..to anybody that knows how to help him with this project..please do so...because theres no emu tht i want more than the genesis one. id even pay for a copy..

[scuddy]

I agree Ive got the snes, ines and mastergear on my n900 but the megadrive is the one I really want as I had one when I was a kid. wish I knew enough about Linux to port it myself

A .gz file extension indicates that the target is a single GZIP compressed file.

Try extracting it with the terminal using:

gzip -d dgen.gz

You would then have to execute it in the terminal:

If the dgen file was uncompressed to the top level of your memory card and you had a ROM called alteredbeast.smd there also, you would type:

/media/mmc1/dgen /media/mmc1/alteredbeast.smd

(please note the single space between dgen and /media)

[scorpio16v]

The only success that i had, was to see the SEGA logo for a second. :o
Seems, there are some compatibility problems, like Arnim remarked.
Anyone knows a working ROM for testing ?

[RDK]

I'll bum the person to get a working genesis/megadrive emu.

If I knew anything about coding/linux etc, I'd spend my life trying to get it to work, but I don't so I fail. Lol

Good luck sirs!

[cjsegninir]

I want a Sega Genesis/Mega Drive emulator too!

If somebody with C/C++, Pascal and Delphi experience can do something to help, send me a PM. However, I'm a total Linux Noob...
