G1-ATA Devices

So, the ideal BIOS to pass the Holly protection would be...

boot_loader_wsc_bfont.bios ?

Would that allow booting the DS core from either SD or IDE too?

Ahh, I think I have a way of testing it...

If I use my DE1 FPGA board and program the Flash chip with boot_loader_wsc_bfont.bios, I could patch whichever part of the code I wanted on-the-fly.

Then, reboot the DC each time (/RESET signal), and have a simple app which tests the G1 access and writes the result back to SD card.

I'll have to solder the extra signals for the DC Flash though (many of them are in parallel with the G1 / IDE adapter of course), but it might not be too bad.

That could be another option for the new Flex cable adapter too - attach it to the extra pins to allow Flash BIOS mods.

I'm probably getting ahead of myself as usual, but I'll have a think about the Holly testing idea.

Oh, also...

Could I ask which original BIOS version boot_loader_wsc_bfont.bios was based on? Was it a US one?

And could you say roughly which address ranges your code was injected into?

I think the bootloader ones are more important to get working, since most people will be using either SD or IDE.

Booting DS from IDE should be pretty fast now, and allows for it to be updated easier.


Thanks,
