FPC4NDS: first raw demo

That sounds like a heck of a lot of headers? What are they all for? :lol: Can't just be for the stylus.

I guess it's almost every little thing to do with the NDS hardware huh?

Two cpu, two cart ports, two screens, a touchscreen, audio, keys, filesystem and wifi: indeed it is a lot of stuff to handle :lol:

Edit: I have requested the account on sourceforge and now I'm waiting for the approval

h2pas works only semi automatic: start conversion, find first crash/error, fix/remove statement and continue.
BTW: You should also get internal errors only after a syntax error.

Hey Florian, nice to see you on PGD!

So what exactly where the latest commits for the GBA platform? And whats the plan for fitting NDS into FPC in the near future?

Sorry, I'm always full of questions, aren't I? :lol:

I have resolved by doing all by hand. 85% it is only search and replace matter, so I'm proceeding very quickly. There is some construct that I can't translate 1:1, like bit fields inside a struct, but I'll provide some bit masking functions, if needed

**Legolas** · 14-12-2006, 06:16 PM

Update: I have committed the changes on freepascal svn. Let me make a zip package and I'll release binaries soon

**WILL** · 14-12-2006, 06:23 PM

And just as soon as I added the platform to the 3rd Party unofficial spot... I move it to the Official ones.... (I'm starting to see what Florian meant.

)

You can. FPC 2.1.1 supports bit packed records.

Nice! So if I have something like

Code:

typedef struct tPERSONAL_DATA &#123;
  u8 RESERVED0&#91;2&#93;;			//!<	??? &#40;0x05 0x00&#41;.

  u8 theme;					//!<	The user's theme color &#40;0-15&#41;.
  u8 birthMonth;			//!<	The user's birth month &#40;1-12&#41;.
  u8 birthDay;				//!<	The user's birth day &#40;1-31&#41;.

  u8 RESERVED1&#91;1&#93;;			//!<	???

---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---

  packed_struct &#123;
    unsigned language    &#58; 3;	//!<	User's language.
    unsigned gbaScreen   &#58; 1;	//!<	GBA screen selection &#40;lower screen if set, otherwise upper screen&#41;.
    unsigned RESERVED3   &#58; 2;	//!<	???
    unsigned autoMode    &#58; 1;	//!<	The DS should boot from the DS cart or GBA cart automatically if one is inserted.
    unsigned RESERVED4   &#58; 1;	//!<	???
  &#125;;
&#125; PACKED PERSONAL_DATA ;

how should I convert that packed_struct part? :think:
