Homebrew Who wants Duke Nukem 3D (JFDuke?) on the DSi?

[mironicurse]

Here is a ROM with improved performance: https://github.com/giulianobelinassi/duke3d-nds/raw/main/duke3d.nds

I've also sent a PR to elhobbs with my changes.

Is it possible that instability appeared due to asynch write to framebuffer? I tried to compile it with latest libnds, fixed unknown types in several places but this is too much for me, and i doubt i'll be able to get it to compile at all . If you have old devkitpro that you've built with, please share it, since devkitpro seems to have no proper versioning and new changes are too drastic for me to fix.

I had stopped working on duke3ds and switched to jfduke3d
https://github.com/elhobbs/jfduke3d
Unfortunately this has not been updated to compile with the latest devkitarm/libnds/calico, but it should be more stable than duke3ds. There is a jfduke3d.nds at the link provided.

just to clarify jfduke3d works fine on my dsi but on ds wont work for me, crashes on pcm_beginplayback then instantly shows pcm_stopplayback with mixbuff equals 0, not sure if its due to error in beginplayback or stopplayback should do so. I'm interested in better fps and stability on ds, but since i believe jfduke wont fit to 4mb i want to try to compile duke3ds. Same settings, tried booting with twilight and dstwo kernel, same thing

The build engine has a lot of static arrays for loading level data. There is a compatibility setting that controls the size of these arrays. The value can be set from 5 to 8. With larger numbers using larger static arrays. Duke3ds has it set to 5 and jfduke3d has it set to 7 … I think … in any case high enough to require a dsi.
The static arrays are globals and contain multi dimensional objects with extensive references throughout the code. Switching them to dynamic would take a lot of effort.
I would recommend just building jfduke3d with compatibility setting to 5.

Hi @elhobbs, how are you? I hope all is well. Over the years, I've tested this port extensively, examining hundreds of custom maps and entire add-on episodes, and, aside from some slowdown and stuttering when dealing with many enemies or in very large, detailed environments, the overall result is truly excellent: playing it is an absolute joy. Welp, but I'd still like to make a very small request, if I may (no rush, just if you have the time and inclination): could the menu font be made larger? The problem mainly concerns the choice of user maps, whose titles are truly illegible, especially on non-XL DSi. Is there anything that can be done about this? Thanks for everything, again and forever, chief.

I am well thank you. It has been a while since I looked at this but my recollection is the menus and the text are very hard to fix. Lots of magic numbers down through every layer of code - layout and rendering. I want to say I made improvements where I could, but maybe I missed something … or maybe the changes were insufficient.
I hope all is good for you as well. It always surprises me when I see that someone plays any of the stuff I put release … though I suspect it is mostly just you

Still playing your ports every month on my side. And I hope there will be a fix for Hexen for DSLite/tank players

is the hexen issue an out of memory error? tank?
I think I need got look at some of the microcontroller ports of doom to see if there are any memory saving ideas I could use.

Yes I think it is a memory problem when you save/load it crashes the game. Sorry I am not at home during few days to check again.

I came back, I managed to fix my DSi
I spent some time trying the port again, and all I can say is that the experience I had playing it was absolutely great

All I can say is that incredible work, elhobbs
