Re: It's no more a MiSTery

I think I did understand what you meant. You meant if software could somehow provoke the CPU/GLUE to assert DMA chip select for more than 16 cycles, right? What I meant is that if something like that could be possible or not, it depends on how many wait states the DMA chip inserts (indirectly thoru...

Re: It's no more a MiSTery

It's not up to the CPU. It's actually up to the DMA chip itself depending on how many wait states it would produce on an access. But no, I don't think it would happen even in the worst case. Yes, but it's not really software-triggerable (I was just speculating if it would be possible to reset the D...

Re: A core that works as a card reader?

MiST as a card reader? And you want to connect via USB to a PC to access it? If it's doable, it doesn't need a core, but must be done in the firmware.

Re: It's no more a MiSTery

But hardware debugging is a very tedious, time-consuming and hard job. No wonder why nobody ironing out the last bugs in cores. I think it is relatively easy as long as you can use a software emulator debugger to compare the traces :) It is several orders of magnitude harder when for some reason yo...

Are you sure it never exits from that loop? No I'm not, I'm just stepping through it in Hatari and guessing. This is not going anywhere, I will try a different approach. If you want to also check on FPGA, I can send you the .stp file I used last time to watch "breakpoints". But hardware d...

That's cool! It's how STe should behave according to the ASIC schematics (and I've implemented it correctly then). No emulator does this.

The Union Demo - Level 16 fullscreen fails to load, just goes back to the main menu. The original on AtariMania is a STX, so I've had to use the version on POV112 from pouet.net. Issue exists in ST and STE mode. I've found the issue, however the fix has a conflict how I interpret a part of the STe ...

Of course it's probably useless. I was asking because I was under the impression that the way you implemented this core was to match the schematics period. :) Of course, I try.

You did it once again, thanks for the patch. Why are you only connecting peripheral_reset to the MFP and YM though?

Re: Work on the Minimig core?

Yes, I notice the disappearing pointer in interlaced pal. Try the attached core, it restores the original behavior with non-programmed blank modes, but retains the "fix" with the programmed ones (like dbl pal).

Btw, I tested the interlaced PAL mode with MagicTV2 and BorderBlank. Originally the left border was much bigger than the right even in this mode, too.
