jEnesisDS 0.6

[TaN00Ki]

I guess I'll check my rom twice, but it works perfect on pc emu.


Lordus, do you know why jEnesisDS keeps on remembering the rom names as I add them to my setup, instead of chronologically, even when I delete jEnesisDS.sav?

[Lordus]

Files are shown in the chronological order they were moved to the SD card (within this order they are sorted alphabetically though). This is just the order they are read from the card, jEnesisDS doesn't sort or remember them. The .sav file doesn't store any information.
So if you wanted the files to be shown alphabetically sorted, when adding new ones, you'd have to delete the ones already there, and move them all together (including the new files) onto your card again.

I know this is not really convenient and will see if i can do something about it.

report: Bonanza Bros worked on the last version but it freezes now.

Nice!
Sonic2 works great except for a graphics glitch and slowdown on water levels. (Flickering bars when above water, underwater is fine)

Yeah, that's one of those games that changes the palette midframe (for the water effect), which is currently a problem. Hopefully this (and the slowdown) will be solved in the next version, but the sound and everything involved took all my time for the current release.

I have speed functions still somewhat and some sound gliches anyway i can alter a file to fix it ;x ? thanks i am running it on a ez5. I dldi patched it already.

Many thanks for this update.. For months I thought sound was not possible!

I noticed the sound FX sounds a bit poor, reminds me of the Genecyst.. e.g. the ring chimes in Sonic don't sound 'right'. I assume this is because PSG runs at 11khz? Could this be improved in future revisions? I could live with the cropping, but sound has to be as near dammit perfect as possible

Thanks again!

@Lordus

Do you know why EUR flagged games are running faster than US/J releases?

There are some games which were only released in EUR which are not working properly and even the sound is faster than it should it.

Great work though, thanks again. :thumbup:

That's what i expected First i was told, please implement any kind of sound, even if it's just some of the sound effects. Then when there is something, people expect it to be perfect and will point out any shortcoming.
The sound currently runs at 16KHz and the ring chimes are not done by the PSG, but on a FM channel. One shortcut i had to take, to make it at all fast enough, is to update the envelope just once per frame, and not per sample. This can affect certain kind of sounds, where the envelope changes rapidly. I hope i can raise the overall sample rate a bit for the next version and slightly improve the sound, but it will most likely never sound like the real thing, sorry.

Yes, because all games run at 60Hz? While poorly converted EUR games that originally run slower than they should will run at normal speed, ones that were properly converted, or even explicitly done for PAL consoles, will run too fast. It is just very convenient for me to sync everything to the DS's refresh rate and to not have an extra handling for PAL games. Is it really worth it? I have my Mega Drives modded to run at 60Hz too, because i always found PAL games too slow

[sarkwalvein]

EUR games go faster because jenesisds uses the DS vsync to limit framerate.

USA and JAP games have a framerate of 60 FPS, that's the same as NDS vsync.

EUR games have a framerate of 50FPS, but are running at 60FPS because of the NDS vsync.

To make EUR games run at the appropiate speed a timed framerate limiter should be used.

Edit: Oops... looks like Lordus replied while I was writing, sorry...

Hi Lordus, i just want to say that this release is bloody amazing! Your hard work is really apreciated, THANK YOU!

I was expecting some sound like 8 bit games, but you did what many considered impossible with the tiny DS, your skills are godlike

Now i wish you the best for next release(s), i hope fullspeed emulation will be possible one day, but your emu already reached the top of the DS homebrew scene with this one :thumbup:
