Re: my SDL ports are darn slow

Thanks for this reply. I wonder how jEnesis does to be so fast, whilist emulating a 68000 & sound! Or the MarcaDS emulator. Ok they don't use SDL but SDL DS actually performs blits using devkitpro, and emulators are pixel-pushing programs too (even if blits can be sometimes emulated with blits but t...

my SDL ports are darn slow

Hi, I have coded some C++/SDL ports of some games (either from me or from other 3rd party developpers), however I found out that the games are darn slow. And I'm wondering if it is not linked to the update from libnds 1.4.1 to libnds 1.4.2 Also what's the fastest mode on the DS? Is that 8-bit? I'm a...

Re: decreasing executable size with gcc options

To my knowledge, objcopy is stripping your elf clean already. It's set up in the rules too. Yeah, so no need for -s switch. I dunno for you, but I'm not using Makefiles for day-to-day coding. I have set up a Code::Blocks project which is able to generate code for NDS or Windows (different targets)....

Re: decreasing executable size with gcc options

Yes, -s is good too, since you don't need debug symbols on the DS :)

Also use -Os instead of -O2. Saves some more bytes.


to sum it up, compile -ffunction-sections, -fdata-sections, -Os, link with --gc-sections and -s

Re: SFX stop playing, Mod refuses to pause/stop/unload correctly

I have downloaded version 1.0.6 of maxmod and replaced the libmm7 and libmm9 of devkitpro 1.5 by the fresh ones (but maybe they were already the newest ones...). I have the same problem here. On No$GBA everything is working fine, but on the real DS, samples stop playing after a few seconds. The game...

Re: homebrew menu freezing

Have you re-downloaded the SVN copy as WinterMute was playing around with a thumb version of the homebrew menu over the last few days and this was on SVN over the last few days. Re-download the SVN do a make clean, and then see if this fixes the issues. I recompiled everything and it get a init fat...

Re: C++ stream function lockup libFAT

About memory concerns, adding ffunction-sections and -Wl,--gc-sections helps (see my post in "suggestions"): http://forums.devkitpro.org/viewtopic.php?f=14&t=1665 Your confusing the file size of the nds file and the memory footprint of STL - it's 2 separate things. Yes you will be removing unused f...

Re: fadein/fadeout in paletted screenmode

5 bits!!! That's more than enough. I have an Amiga so I know how to stay humble when it come to color. I'll try this, looks very interesting for what I want to do. Thanks EDIT: works fine and is very simple !!!! I hate this generic SDL shit when it comes to the DS: you have 2 registers to poke into,...
