There are two versions, ZXDS.nds for Slot-1 (DS slot) based cards, and ZXDS.ds.gba for Slot-2 (GBA slot) based cards. Just choose the one which suits your card best.

The provided executable was already patched with the r4tf.dldi DLDI driver, so it works fine on both my M3 DS Simply and M3 Mini SD Perfect. Of course, it should work fine on any other card which supports DLDI as well. Just give it a try and you will see. If it won't work for you right away, you might need to patch it with a specific DLDI driver for your card with a DLDI patcher, both of which you can find here. It might be wise to patch it in either case, just to make sure you have the most recent version of the DLDI driver for your card. If it still doesn't work, I am really sorry, but there is not much I can do about it. Please do NOT contact me regarding if it works or doesn't work on your card, at least at this point of time.

You should also copy some snapshots or tape files to your card. Either SNA/Z80 snapshots or TAP/TZX/PZX tape files are supported. You can place them anywhere you want, although the /ZXDS directory is looked up first by default. For your convenience, I have included few Spectrum games in SNA or TAP format, so you can at least give it a go.

Phew, looks like Quake GameCube was pretty popular. As of now, it’s been downloaded 362 times. Who knew there were so many GameCube homebrew fans!

There’s all kinds of discussion going on about it on various forums and as much as I’d like to respond to all the queries, all those forums are just way too much to keep up with. So what I’ll do is cover the main points here.

Some folks have quite reasonably supposed that there won’t be any more GameCube homebrew from me because my Wii isn’t capable of running SD Media Launcher any more. The good news is that I do my development using a regular purple GameCube connected to my PC via a TV card. I think I would go insane if I were using the Wii as my main development console. It takes so long to start up and get into GameCube mode!

I really should have put a new post up here when I released Quake, as many sites have copied and pasted my last Quake post into their news items.

Additionally, I really should have put up a screenshot. Many sites used screenshots from GLQuake or highly modified Quake engines to illustrate their news posts, which is a shame because the shots they used don’t represent what the GameCube port looks like.

In terms of gameplay, some people don’t like the way the view centres itself vertically if you start moving. I think this is a Quake feature rather than a GameCube port feature and there should be something useful (”lookspring”?) in the options screen if you want to disable it. I like it on, so I never thought about it.

It’s unlikely that I’ll be doing any updates on Quake soon, mostly because I’m getting stuck into a new project at work and annoying network card issues have caused me to lose some schedule time, but partly because I’m pretty happy with Quake and there don’t seem to be any glaring issues that need fixed ASAP. That’s a first!

Anyway, I’m glad people seem to like the port and hopefully there’ll be something else for you in the coming months.

As I was concentrating on Quake, the GameCube ports of SDL or Cave Story haven’t really progressed much since I wrote about them last.

Simon Parzer has been working on the SDL port of Cave Story. He’s been doing a great job implementing a mixer for sound effects and music. We’re sharing the same Subversion repository so he can port to Linux and GP2X while I port to GameCube.

The GameCube port of SDL is going okay. The only problem I see is with the audio system. SDL won’t convert audio properly when the frequency change isn’t a power of two. Unfortunately the GameCube plays only 32KHz and 48KHz audio, which isn’t very common, and SDL won’t convert correctly between those frequencies and the usual suspects like 11KHz, 22KHz or 44KHz. This is due to be fixed in SDL 1.3, but until then I’ll need to write an on-the-fly rate conversion routine.

After I get back on schedule with work I’ll pick up SDL again. I hope once SDL is released that the flood gates will open for loads more GameCube ports. The scene seems a bit bare. I think the recent GameCube homebrew contest at DCemu only had one entrant!
