ST536 STE EDITION

[Steve]

Unfortunately I put together my IDE SD card after the 144 board became stable for me, so I felt no need to go to all the effort to set up HDDriver-supporting partitions. It now means it's useless for testing outside of EmuTOS.

You realise you can just install HD-Driver on that same setup, when you boot EmuTOS it'll ignore HD-Driver, when you boot Tos206 it'll use HDDriver, no need to re-partition.

I haven't used a partition format HDDriver understands and for half the drives I've not used a filesystem TOS understands.

HDDriver can see some of the partitions when run from floppy but can't open them. I went for usability rather than compatibility as I'd kind of put a lid on testing. Then the 288 version came along. :)

CURRENT15A firmware is up. (EDIT: But likely still issues it seems :( )

This one includes the external glitter BR fix. 8MHz clock sync fix. IDE AB fixes, the 8 MHz problem was also manifesting on top of the IDE AB code. The second problem was the patch address I think was glitching for IDE AB. So I've rebuilt that chunk of code to "hopefully" make it more robust..

I'm still running on the external blitter board.. I need to reset the integrated blitter boards later.

This is what I'm up against, this is the IRQ signal...

So I need to rebuild the logic again :roll:

I also think that IDE doesn't like running with the CPU at 50mhz, even though its all timed to the CLK8 anyway.

Nice ringing...

Finally figured out how to get the H Atari debugger to work in windows!

So loading DOTT..

looks like it crashes at 00FA0058 :shrug: anyone tell anything from this ?! All I can tell is its trying to access the cartridge port for some bizarre reason ?!

This is what it does when MAPROM is loaded..

The corruption is pretty much identical every run there is some moving pixels at the top of the screen and there does appear to be three sampled sounds playing but they are corrupted so cannot tell what they are saying that all.

Maybe it's because of the MMU tables not been set properly for the 030 CPU :shrug:

There's a lot of PAK patches in the mix. So will just disable those for the hell of it, see what happens.

That's kinda how it looks when you point the shifter display address at 0x00000000 :p

The changing dots at the top, near the corner is a tell.

Yeah the pixels around the first line change a bit. Assume its why DMA sound is screwed up as well. But why that happens.. no idea :(

MAPROM must setup something to get the game running, but something is still broken somewhere.

Just a quick update on the new STE I'm testing on.

Works identically to my first STE using firmware current13. Under EmuTOS everything runs perfectly. Under modified TOS 2.06 most working just great. DOTT crashes in TOS 2.06, but not EmuTOS.

I was kind of hoping for a different result, but on the positive side...the results are repeatable.
