As someone asked, I have made some little examples showing fpc4gba in action ^_^ Here some screenshos:    Download hereDemo 1 and 2 are double buffered mode4 (256 colors palettized); 3 is a mode0 demo converted in pascal that I have taken from a japanese site, IIRC... Executables are not smartlinked and are fixed with gbafix, in order to make it runnable on real hardware (tested on a DS in gba mode and all works fine ^_^) |

AFAIK you should have a flashcart or a pc<->gba cable, but in this second case, there is a limitation to the size of executables you can send to gba. More, IIRC, cable send requires a rom specifically built for multiboot, but at this time my crt0 does not allow multibooting  |

How did you test it on a DS?

How did you test it on a DS? With an M3 SD, a gba cart that uses Secure Digital memories for storage. |

Btw, Have you sent the FPC guys these shots. I think it's worthy of putting on their home page!
Btw, I just posted a news item about it here.

A news posting on the FPC site will appear tonight.
Files are okay if you want to add files or overwrite GBA specific files. If you want to change files, please submit patches.
The best way to submit patches is:
* Make a checkout of the SVN repository.
* Modify it like how you want the code to be.
* Send the output of the "svn diff" command to one of the developers.

Regarding speed, what's currently the status? I guess we still need thumb code generation?

Regarding speed, what's currently the status? I guess we still need thumb code generation? AFAICS, speed is pretty good. Compared to gcc similar code, the speed is the same. Main bottleneck was mod/div but in the new rtl I have replaced it with internal GBA BIOS functions. These internal funcitons aren't very optimized (a div operation requires about 60 cycles), so it could be nice to replace it with some more optimized asm code (I have found some asm div routines optimized for gba, but I'm not able to make it working). However, for our initial purposes, the bios one should be good enough. |
