Quake 2 for DS WIP Update

[bassCore]

I have the M3CF, with 32 megs of ram i guees. Are there different versions for slot 1 and 2 cards, like M3Simply/M3CF or how does it work?

Well, looks like I'll have to get my hands on a RAM expansion. Can anyone recommend a slot-2 homebrew device that has 32 megs of extra RAM?

Anyways, this is great news. The more brilliant FPS games the DS gets, the better. Keep it up.

Coolness

Hey man it's a THOUGHT to make it ONLY for 2 slot solutions OR 1 slots with a EXRAM pack!

simonjhall - awesome work! Will you release the source code, when it's done? Here's a Quake 2 to PSP port DevBlog by McZonk: http://emergencyexit.untergrund.net/
He (McZonk) also has huge problems with low memory (PSP has free 24 megs user RAM partition and no virtual memory) - your optimizations may be useful, and his (sources of the latest Q2-PSP public beta are avaluable there) may be too for your project!

God speed to ya Simon. Don't care a thing about the slowdown of using the EXRAM builds. So do what you need to just make it work. And screw colored lighting.

Did a load of Q2 today, and I've decided to make a quick video (with me actually playing it) and stick it up your youtube, in order to show those "OMG 1fps!!1112" naysayers that the Quake2 on the DS is a very real possibility.
So anyway, here's me buzzing around the entry level. It's surprisingly hard to make a video of the DS, as well as use it at the same time :-)
The reason I never actually shoot the bad guys is cos I can't reach the L shoulder button due to the makeshift camera mount I made!

The framerate is still crap, but this time it's not due to the software renderer taking all the cycles. This time all the rendering's on the GPU, but the CPU hog is all the floating-point code used to set up the rendering.
Also the white pop-in is when the game runs out of VRAM and some new textures need to load in, so something has to be freed.



And here's a few pictures (much sharper)



Comments?

Yeah suggestion for which Slot2 cards support 32meg would be most welcomed by me also!

[simonjhall]

So far, RAM doesn't seem to be a serious problem. Granted, I've only played through a few levels so I'm not yet sure why the PSP is having problems with memory. Running the level in the video was taking ~12 meg of RAM (4 + 8), and I could probably shrink it by streaming the textures from disk like I did with Q1.
There's still no chance of being able to play the game without slot-2 memory though.

Regarding which card to buy, I'd hold your horses a bit! I've still not decided if I'm gonna actually do the game due to the amount of work involved. At the moment it only runs on the 32MB Supercard, but there's no reason it won't run on any other 32MB card (eg the M3). At this stage it *ought* to run on a 16MB card, and if I get the time then I'll confirm that this is so. My 16MB EZ 3-in-1 is definately faster than my 32MB Supercard...

That's damned impressive (the vid). How you manage to get it working on the lil'DS in the first place is something else.
