Falcon's is FA 52 23 5F. I don't recall what the normal ST one is, but I don't remember hearing they're different.

I think it might be that hatari needs a different format of file not just a raw dump of the cart rom.

I never got anything but TOS404 to run in Hatari. Maybe they fixed that by now, no idea but I never even got 402 to work. I think someone said it patches some stuff to work.

Just had a quick experiment with EmuTOS cartridge version -- Hatari boots that fine in Falcon mode (same magic, BTW).

DiagROM cart version works on Hatari in ST and STE mode, but not Falcon mode so I don't think there's a separate format.

As I say, the genuine Atari Falcon Test Cart doesn't work in Hatari either, so I wouldn't necessarily say it's a conclusive proof it won't work.

I need to figure out how to get that ROM burner past the missus. Bloody lockdown!

Hatari is pretty good these days and I think only patches TOS when you ask it to (fancy screen modes, fast booting selected, etc). 402 (and Emutos) certainly boots, but it's not perfect as the test cart failing shows & the 030 emulation is slower than a wet weekend in the West Country on my (steam powered) laptop.

This version works via serial port on the falcon in hatari.

No VIDEL support so no display.

If someone can give me some code to setup a st style screen on a falcon i'll add it.

EDIT: have updated DiagROMST to produce a Falcon binary.

This is very cool, thanks TF. I confess I can't get any output on the emulated serial in my Hatari invocation as yet, though, but ten minutes when I'm meant to be working wasn't a very thorough test!

It occurs to me I can probably use this by simply hotwiring a flash chip up to the top of my board and pulling the system ROM chip, so that's my project this week, I reckon. :D

Working video added. Just got hatari to capture the register writes for a Med Res compatibility mode and pumped them out in the right order.

Binaries on github.
