Can a Homebrew Only Flash Cart Be Made ?

[Brifry]

I don't believe this is true. The read speed affects the loading time, but once the game is loaded the speed will be the same for all DS systems regardless of the brand of flash cart used. The only exception is when data is streamed from the card, like during video playback.

Yeah, that is actually exactly how you describe booting stuff up with the GnM. Like Mini vMac DS takes about 30 seconds to boot up, but once it's booted, it works great, full speed, everything. Same with ScummVM DS and a lot of other more complicated homebrew.

would like to see how you run 1945, it's a shoot em up that when played along side my MMD or R4 has obvious slow downs especially during explosions.My FPS seems to be good even during slowdowns...Yes I know that streaming video has lag but the before mentioned 1945 is nearly 86 MB, Doom wads are much more then the 4mb as is Quake.

Ok, well I don't think I'd have any problem with that at all. If it's on the Neo Geo compatibility chart, it'll work. Like I said, everything on that chart works. I have SVC Vs Capcom working and that's about 90 MB when it's converted, it's not the size that's the issue. It's all the sprites, complexity of the game, that kind of thing? But it runs at the same speed labeled.

I think maybe you're the one missing the point here. I've actually looked it up, and from what I can see, there is basically a problem with the Games n Music card playing games over 4MB in size, which sounds like it would cause problems for homebrew games as well.

Ok, that's true, if there's no DLDI. If you can patch it, the size doesn't matter, that's only valid if there's no patching. And last time I checked, most homebrew include that now.

So that just brings it back to my original point if there aren't any problems with files over 4MB. All it requires is a firmware hack to play roms, hence GnM can't truly be considered a homebrew ONLY card.
If this hack hasn't been done, it's only because the presence of other homebrew cards make it pointless to go to the effort of figuring out how to hack it.

And don't you have to stream the NDS roms? I know someone hacked the Max Media Dock so you can use commercial roms, and that's from Datel, which uses basically the exact same firmware. And from what I hear about it, it's just unbearable to play the roms, because it's so slow. Maybe I'm wrong, but it sounds like that situation would unfold with the Games n Music also?

* The ability to auto-run a file on startup, which would give an easy and safe (no need to risk re-flashing the card) option for homebrew coders to create their own menu's.

Isn't this already implemented? I thought that you just change the name of the file (whatever it is, menu, app, etc.) to bootme.nds and it should startup. Was that it? I know I changed the name on one of my files and it automatically would boot up, I can't remember right now.

* Auto DLDI patching.

I've seen that, and it supposedly works. I haven't tried it myself, I just use DLDIrc before I put something on my card. Here's the link: http://hbnds.awardspace.com/index.php?topic=101.0

Or, here's the download link he posted: http://www.megaupload.com/?d=TFVB14BB I guess you just put this and the "Gmtf.dldi" in the root of the card,and rename the it to "patch.dldi"

I'm not knocking the GnM, just stating there are some downsides to it.
I own a MMD, two GnMs and an R4, and I'm telling you that some NeoGeo games run slower on the GnM(like 1945) then on the MMD or R4, even though it shows no drop in FPS at all. I'm not trying to make you feel bad, just report what I found.
The above slowdown happens regardless of microSD used or version of DLDI.

No worries bro. I was just stating that I haven't had any problems with the Neo Geo Roms, everything is normal for me, if you look at the compatibility chart. Oh, and I just checked, bootme.nds does start up any program automatically.

My comments about auto dldi patching and using the bootme.nds were part of the answer to the question about ideal features of a card. I know the GnM has these features, but there are some features that it does not.

Oh, sorry. I thought you were saying that those are features you'd like to see on the GnM.

I'm confused, are you saying that you play games like Prehistoric Isle, 1945 and Blazing Star without slowdown on your GnM?
I'm not talking about compatibility which is of course,the same as any other dldi card.

No sorry. I actually haven't tried any of those games on it. What I'm trying to say, and I had a bad way of describing it, is that my results are the same as those displayed on that compatibility chart for NeoDS. I can't remember where I downloaded it, but I guess here's a place where it's posted: http://soulmilk.tistory.com/6
What I'm saying is I get exactly what it says it should be i.e. 45-50 fps on Svc Vs Capcom, etc.
