that gba header won't work on a real gba, the logo needs to be the nintendo logo (it's kind of a checksum), and the checsum at the end shouldn't be 0 either.

So THAT's why the nintendo logo is garbled when the cartridge is dusty

I have tryed this on my real GBA and works fine, i have also seen the code in the screen shot and it uses the same header. They seem to be real GBA and nintendo DS device's to me
All the Flash rom cartridge's that i have heard of come with a some kind of menu which does the checksum! plus it would be border line ileagle to put a real rom logo and checksum ect....but as you can see from the above screenshot does not need it |

Dex4u 29 Aug 2006, 20:10
Well i think you may of been reading the wrong tuts, as it works fine on my real GBA and DS
.
And its used in this demo: http://www.dex4u.com/images/gbademo.jpg Remember 99% of people that try it, will be using a flash cart that boots to a menu. |

setrodox 30 Aug 2006, 15:23
well, with a menu it works obviously, as the header of that launcher gets checked by the gba, the menu then just jumps into the code of the app/game, without the header. but there are still old cartridges around which don't have a launcher/menu. you disable those people to use dex4u

Dex4u 30 Aug 2006, 18:04
Your right, But i have a multi-boot compliant header that is much bigger, and can be used for such a old cartrighes, but i tryed to keep it simple for a basic demo

I have updated the attachment at post #1 in this thread.
Two changes: 1) Support for FASM 1.67.x, now you can compile the LINUX binary with v1.67.7 2) Added the accounting info such as SizeOFCode etc. as dicussed with vid a few days ago.

FASMARM has it's own webpage http://arm.flatassembler.net
Tomasz Grysztar was kind enough to offer some web space so many thanks go to him for that. In the interests of keeping this message board free from excess attachments I will remove the attachment at the head of this thread. So if you need to download FASMARM go to the url above. The page is very basic and minimalistic, so don't expect too much. Just the essentials. As usual, any problems or question etc. feel free to post them here. |

you can find "Device Emulator" downloadable from Microsoft, but you will also need ActiveSync, you can download it too. or they are installed with Visual Studio 2005.
