Homebrew Updates about nesDS...

[migles]

glad to see an update just when i was to download a nes emulator for the ds

thank you. continue your good work

Curious, is the updated build of nesDS on filetrip now?

 

[ferret7463]

i'm getting a lot of guru errors with the latest build on my DStwo.
this one happened when using an on-the-fly .ips patch before trying to boot the game Recca
pc:02008DD8 addr:03000000

I am getting alot of those on my DS2 as well. All of my patches were applied before i put them on the SD and i use Luna .IPS . I have downgraded back to a older version for now. Thank you for the effort though.

OK is any plans at all to add more data on the address line? I mean yeah I know that you don't exactly have a ton of space but it makes it really hard to add cheats to it as I'm only given 12bits of precision for the addresses, which means adding fceux cheats which this one seems to do similarly are near impossible, that and in addition the way the cheats are stored(binary file), makes it so that applying cheats is very hard to really do.

As far as what others have said for me it's just kid icarus that i've found thusfar, I don't know about the rest of you but that game only doesn't run with the latest one. i tried half a dozen others with my dstwo.


edit: i'm a stupid, you're only touching the internal ram on the NES whereas kidicarus and I imagine quite a lot of other games are using external ram to store a lot of things. So thisi should be changed to allow you to search past the NES ram to the SRAM.

Unfortunately the new update still won't work with my DSTWO after the initial boot, just gives me white screens. Guess I'm stuck with good old 0.5a2... Anyone else have this problem?

EDIT: Just checked the ini before even running it, there's all kinds of "ÊÇ·ñÇл»A¡¢B¼üµÄ¹¦ÄÜ". Is it supposed to be like that?

Ive checked/debugged the code of FCEUX in the last few days, about ppu and mmc5.
I found that the mmc5 is almost embedded to ppu core, and there are some hacks in mmc5 functionality. All of them make it hard to emu the tricks.
I played the Rom City Rampage, pretty well on FCEUX. When debugged on FCEUX, I cannot even locate the CHR TILE of the first title screen. Out off my knowledge of NES EMU.....
I'd say the MMC5 is too powerful and I'm afraid the games with mmc5 wont work well on nesDS.

Guru Errors? Same here with a DS2. I tried a few roms with the new version but only about 50% work though the older version could handle them.

One funny thing worth to mention is that the German Maniac Mansion gives out a Guru and the US one doesn't.

I'm changing back to the older version now. But don't get me wrong I really like to see that this is still work in progress.

I'm getting Guru Errors on my R4i 3DS while trying different Famicom Disk System games. On 1.3a, I'd hear the boot sound with no visuals.

Huiminghao: There must be some way of keeping the progress you made with MMC5 and leave the old functionality intact. If you could manage that - I would be more than happy.

So I had some time to investigate the latest source of nesDS and it turns out - it seems to be OK!

You can't rely on the version 'nesDS_latest.tar.gz' downloadable from: http://sourceforge.net/projects/nesds/files/nesDS_latest.tar.gz/download
That version is going to MALFUNCTION.

Instead, you have to download the LATEST source AND replace the two files 'stepdebug.c' and 'subscreen.c' with the corresponding ones from version 1.3a - then make your own build.

I'm sure about the file 'stepdebug.c' - the changes in that file can lead to crashes for games that worked properly with version 1.3a, but since the modifications in 'subscreen.c' is most likely to display data gathered by the changes in 'stepdebug.c' - you might as well replace that file also.

This will (hopefully) give you a version that is fully compatible with 1.3a AND can play 'Zelda - The Legend of Link'!

I will test all my NES roms carfully and report if I find any game that breaks BUT I feel quite confident I will not find any......knock on wood...

Could you please link your version? I don't have a compiling environment set up and would like to see if this version will work on my DSTWO, as the latest version whitescreens after the first boot.

Give this a try: http://filetrip.net/dl?qeLcMER60S

I am 100% certain this version works on a dsTWO (I have this card myself) so if this give you white-screens your sd-card propably needs a re-formatting.

Please revert back when you downloaded the special build and your test-results, did all games you try work correctly (that did work OK with version 1.3a)?

That didn't do it. First time, it boots just fine, second time I get white screen as soon as I start the emulator. What cluster size do you have, or does that make a difference? Something got changed after 0.52a that makes it do this for me.

I have done nothing special with my sd card. Formatted it FAT with windows (Vista) and then runned SD formatter 3.1.

If this does not work - you will have to buy a new sd card, because the nesDS version 1.3a (and 1.3b) SHOULD work.

EDIT: I have successfully completed the game that crashed before (when I did not exclude the two files mentioned earlier from the build) and another two. Also played an additional two for a considerable time and no crashes have occured.

Huiminghao: Please make a note to either fix OR revert the two files (stepdebug.c and subscreen.c) for the next official release.

I still can't get fds to work. I have the required bios file and all I hear is the fds start up and then an error. Also the screen is black, no picture.

And your FDS games worked correctly in 1.3a?

Remember - if you had problems with 1.3a, you WILL HAVE THE SAME problems with 1.3b!

The ONLY difference should be that 1.3b plays the hack 'Zelda - the Legend of Link'.

There is NO problem with FDS in 1.3a (and 1.3b) - you just have to make sure the files have the correct header.

Take a look at this: http://gbatemp.net/threads/how-to-fix-fds-roms-for-nesds.352987/

Please make sure your bug reports are RELEVANT before posting.

Thanks for the info. I added the extra 16 bytes but I still got an error. Turns out my ROMs were overdumped. All good though as I found the correct ones.

 

[Sporty824]

Hey, so I downloaded NesDS about aweek ago and it has been great. I just would like to know if there is a way to save input settings. I would rather have the the a and b buttons be a and b with x and y being the turbo buttons. The BA Swap works fine but is there a way to save it so it always does that and I don't have to reset it every time I open the emulator?

 

[XDel]

Aghhhh, so here is where the alt version was hiding. Now I can finally play Zelda - The Legend of Link on the (3)DSXL
