Homebrew Updates about nesDS...

cloudskipa · Mar 28, 2011

Hi, just wanted to say many thanks for working on this emulator and for being so generous to take request.

I personally would like to see Pinbot working, it's completely unplayable with garbled graphics which is shame.

I's also love if you could possibly add a bilinear filter to the emulator, I find that there are no filter options to disguise the ugly scaling issues.

Also is it possible to make the sound louder at all?

Thank you so much, I love this emulator and playing NES on DS just feels so great!

Another Great update from Huimingao... Thanks

This has been asked a few times and the answer is no.
The sound level is the sound level.

Well... Yay FDS support!
Boo being late to the party lol.

I updated my svn, and I noticed a new file... "\arm9\source\mappers\map20.s"
Ran the Make command and got an error: "Error: file not found: diskbios.bin"
A quick google search for "<a href="http://www.google.com/search?q=nes+mapper+20" target="_blank">nes mapper 20</a>" leads me to <a href="http://www.zophar.net/wwwthreads/showflat.php?Cat=&Board=general&Number=290005&page=5&view=expanded&sb=5&o=0" target="_blank">this post</a>:<div class='quotetop'>QUOTE</div><div class='quotemain'>In reply to:

One single question. Is there any NES emulator that supports mapper 20?
--------------------------------------------------------------------------------

*checks iNES header checker info*

"20 - FDS"</div>

Only problem is, the FDS disk image is "Disksys.rom", not "diskbios.bin", so it's possible that this is a custom file?
</div>

Maybe the source of VirtuaNes can help, I saw a file called FDS in the directory Mapper, in NES, and int it mentions a "GetDISKBIOS()"...

Look at huminghao's signature...he does plan to add it.

Cool. It will be nice if some time down the line the DS mic is enabled for FDS features like haggling in Kid Icarus and killing the big-eared baddies in Legend of Zelda.

I've got one issue with the current versions which I just wanted to ask here about (in the hope that it can be fixed). Currently using 046 version.

When I load any game, at first it doesnt display the game correctly and there are small parts of the image missing. It kinda looks like a certain few scanlines in the display are missing, very hard to explain but easier to see problem when you look at it. Display is almost perfect though so doesnt look too bad (some might just think its normal and just caused by the scaling).

If I go to the settings and just change that display option (the flicker/alerp thing) from the default setting to another eg "flicker", nesds then corrects the display and its perfect. I then set that option back to the default. No more problem display, but I have to do this after loading each game.

I hope this is readable.
Thanks.
It's in the INI file:CODE;0=flicker 1=noflicker 2=alphalerp
Blend=0

Click to expand...

Default is 1.

No thats not what I meant but thanks for replying.
I have to "touch" that option before the game will display correctly. The graphics always look like small parts are missing after a rom is first loaded. I have to adjust that setting once after loading a game and change it from default to any other option (then the missing parts re-appear) and then back to its original setting (now it looks perfectly fine no missing pixels, lines or whatever). Say for example .ini default is flicker, when I load a game it doesnt look as it should, but if I quickly switch it to noflicker (fixed) then back to flicker (stays fixed), then it clears up the problem and i now have my original default setting but no more problem missing pixel/scanlines.
I need to get some photos to illustrate what I mean, pretty sure I read someone else mention same thing earlier in this thread I'll also see if I can find that post. I thought it was a not very obvious bug.

Though it seems unlikely that it would occur frequently enough to give the impression you describe, perhaps you are inadvertently adjusting the scale of the screen. I've had that happen to me a few times, as the area to adjust seems to extend throughout the touch screen, and it's pretty sensitive.

If you do manage to add FDS support, you will be awesome forever.
FDS support + DPCM sound = win.

Though it seems unlikely that it would occur frequently enough to give the impression you describe, perhaps you are inadvertently adjusting the scale of the screen. I've had that happen to me a few times, as the area to adjust seems to extend throughout the touch screen, and it's pretty sensitive.

Agree... I think this is an issue where you're unscaling the display just enough to get it to look right without loosing too much screen.

Also is it possible to make the sound louder at all?

Click to expand...

This has been asked a few times and the answer is no.
The sound level is the sound level.
Well... Yay FDS support!
Boo being late to the party lol.

E... I just enhanced the sound thing. Now the max volume is twice as former. nesDS used two sound channel to render the NES'sound. Now it uses 6 channels. so the volume could be larger... If 10 channels are used, the max volume could be 4 or even 8 times... But arm7 of NDS wont be able to handle that, because of lack of speed...
Maybe later the PCM sound can be rendered..

I have not done the FDS thing... Yes, the codes are ported form 'Virtuanes'. There are also lots of other codes ported from 'Virtuanes', e.g. mapper4's patch, mapper163(from Virtuanesex, made by a Chinese)... I have to change them to fit NDS...

If you are still interested in bootstub, test
http://www.mediafire.com/file/cc4tunwxhkyfkyo/nesds046a1.7z
Again,
1. copy hbmenu to /boot.nds
2. launch boot.nds from Primary Kernel
3. launch nesDS
4. just press L+R+START+SELECT in emulation

Without your test, I might have to remove softreset from current nesDS (which actually isn't working at all)
I mean forcing to poweroff even when it is loaded from hbmenu (which will be against WinterMute).

----
As for FDS, actually nesterDS+ already support it, but unfortunately its source is not open.

YES. Thank you! You're amazing.
*seal of approval*
So I guess everyone's waiting for the FDS update now.

(also, I'm still occasionally having the sound issues that people were getting earlier)

OK I did further test using my AK2i.

If (using RPGS_Acekard AK2 v3.dldi && loaded from hbmenu), Guru Meditation Error occurs.
Actually I had issues with YSMenu on RPGS_Acekard AK2 v2.dldi before, so perhaps some issues remains...
Replacing /__aio/ak2_sd.dldi with Acekard2 4.23 dldi will fix the problem.
Or in this test you can safely use (your favorite filer)

Done. It's working now.

When run from HBMenu, L+R+START+SELECT = Reset to HBMenu.
When run from XenoFile, L+R+START+SELECT = DS powers off.
When run from AKAIO, L+R+START+SELECT = DS powers off.

OK, seeing my/twiztidsinz's/huiminghao's result, it seems to be safe to merge my patch to svn

Thank you so much.
