This is an email we sent to SuperCard a few days ago. Since then, there was no reply. That's why we're asking for a more direct way of contact. I know there are many Chinese users on here that may have some kind of contact with the team.

So I am working on a proper port of picoc to the DS as my Homebrew Bounty project. I only started working on it today, though.

picoc is a C interpreter with 99% of the ANSI C standard supported. That's right, it's an interpreter.

CURRENT PORT FEATURES:
- a quick port of the picoc interactive shell
- most C standard functions supported
- DS-specific functions added (with more coming!)

HOW TO USE:

Self-explanatory, really. Just input C code into the shell.



Sometimes in interactive mode you want to change a function or redeclare a variable. You can do this using the "delete" statement:



You may want to load C files that you've prepared before. Let's assume you want to load test1.c, which is located in the main directory of your SD card. To do that, do this:



You can now use functions and code from that C file!

Works in both DS and DSi mode, and it's quite fast!

For more information please consult the README or the picoc wiki.

MILESTONES (bXX - build XX):
M1 (done at b02)
- Have it work (b01)
- Most standard C functions working (b02)

M2 (done at b04)
- Add some of the NDS-specific functions (began at b03, still in progress)
- Add loading C files (b04)

M3
Idk. Maybe integrate a text editor?

I fixed the links now

Here I'll post my DSTwo apps.

First of all comes a benchmark for the DSTwo (a port of Linpack).
Notice that as the DSTwo uses software floating-point, floating-point operations WILL be slow. (I will try to port a benchmark which does not use floating-point later).

I've done it!

I was trying to do it for Pate (read: bug/testing reports)... didn't expect it worked.

Tutorial:
1. Get Windows 2.03 (or any 2.0x version).
2. Copy the files from all 9 disks to your SD card (all to one folder, that's the installer)
3. Use DS2x86 (if it fails, use DSx86 instead) to install: IBM CGA graphics adapter, no mouse/pointing device, US keyboard, no printer
4. Run Windows 2.03 from DS2x86 (remember to type "ver 3.30" earlier)
5. Enjoy!

MUCH MORE COMPLICATED MANUAL FOR 0.01:


EDIT: Installing a PS/2 mouse driver makes Windows 2.03 crash while booting (returns to console). So no mouse yet

Hello. This is a small list of tips for DSTwo programmers. Seeing as the SDK is not the best, you may need them.

1. You really should include ds2_malloc.h if you use malloc() and others.
Why? Because by default it'll use the GCC standard libraries, which have a broken malloc(). ds2_malloc.h adds the DSTwo-specific malloc functions.
A similar situation is to include fs_api.h if you use fopen()...

2. stat() does not exist.
Workaround: Use opendir()/closedir() and readdir_ex() to get the stat data.

3. For directory functions, the directory should be "fat:/", "fat:/dir0" or "fat:" and not "fat:/dir0/"

If you know any other tips, feel free to mention them here!
