DGen v1.70 (Genesis Emulator for the PSP)

[D_Rad]

Whenever i try to put an emulator onto my psp, and i have the 1.5 firmware, i always get a message that says some contents may be lost, and then it says ":encryptable:$DATA", and this ends up making the data corrupted, if anyone knows how to fix this please help!!

are we gona see any updates for this emu in the future? it has been almost a year now, I was playing sonic 1-3 the other day and i can really notice a slowdown in frame rates between the three games.

I noticed that sonic one had some huge bugs when trying to laod the saved states and I just can't seem to get more than 55fps without frame skip on, it looks good at frame skip1 but even better with it turned on!

I've played all the Sonic games with it and it runs fine. 30fps is what games should typically be aiming for. 55fps is incredible.....while anything over 60fps can't be registered with the human eye.

errr... games should be aiming for 50 / 60 fps depending on whether they are running as PAL or NTSC, as this is the speed the original machines run at.


This emulator could use development, but the key factor for getting more speed will be the 68000 processor core, for which there is the FAME/C core as a faster alternative, but tests with PSPUAE have proved it to be somewhat less compatible.

If DGen was open-source i'm sure there would be progress. Maybe someone should lobby the authors to release it.

DGen is open-source, DGen/SDL official website

sorry, i should have specified that the PSP version needs to be open source.

"Download source code for Linux, FreeBSD, BeOS, or MacOS X."

i do think its a bit cheeky to make a port based on other peoples work, and then not make that source open as well.

ye 50+FPS with sound would be great but as I mentioned there are a few problems with the save states and some games just crashing

I can't get the emulator to work. I have custom firmware 3.71 and have tried to put the files in a folder called Dgen into both the Game and Game150 folder and it says 'the game could not be started' when I try and run it. Other homebrew works fine.

Any ideas much appreciated

Yes, some games like Jurassic Park crashes the emulator. Change the mode to Normal instead Performance. If it not work you must another emulator (Megaman: Wily Wars dont run in DGEN)

You instaled the 1.50 add-on ? DGEN requires the 1.50 kernel to run and 3.71 M33-2 doesnt come with it.

This problem occurs with me when i copy the emulator from a MS to another.DGEN shuts of my PS P . Just delete the two folders of the emulator in the MS and unzip again the contents of the zip file of the emulator in GAME150.
