It's no more a MiSTery

[slingshot]

My slog through the POV disks has turned up something!

POV 7.

The Pro Replay demo. If you try to play the various on-demand samples F1-F5, the screen will start flashing as if it's depacking something, it'll make a lot of crunchy noises, and it will crash.

Interestingly this demo works in STEroids mode. Something reacts slowly, 99% it's an MFP problem, maybe it does something too fast compared to the CPU.

I've opened an issue here for non-working demos:

https://github.com/gyurco/MiSTery/issues/3

Don't feel the force currently to start debugging, but still good to collect them. (Dreaming about some of you starts to use Hatari or STeem debugger to find out what the crashing demos expect). Actually I believe 3 out of 4 crash happens because something in MFP (which is only tweaked by trial and error).

Thank you! Should I add others that I happen to run across as comments to this issue (assuming it's still open when I do)?

I'll still be moving at my glacial pace, so I don't expect to swamp you with things.

Of course. Good to have them collected together.

As the video signals (especially sync signals) are faithfully reproduced from the original schematics of the main ASIC, it won't be changed. It can be some FPGA-specific thing which produces a glitch, or more likely something with your display which doesn't agree fully with the video. As it has the same timing as the original, it would worth to try an original ST(e) machine if it produces the same glitch or not.

Hi Slingshot, I've finally managed to test the Cuddly Demo Fullscreen on a new screen using original hardware, and there is no problem. Testing the same screen using the MiST and it still had the fade-to-dark problem.

I've tried 5 different LCD screens now, from 3 different manufacturers, and they've all shown the same issue.

The only screen that it's worked correctly on is a Sony CRT.

And centering looks the same with original STs and MiST? (Btw, you tried an ST or STe?)

[Total Eclipse]

The image is centered as far as I can see, no issues with that compared to original hw.

Tested on a ST only, unfortunately I have no access to a STe.

I've update the 3Gb image with tons of utils and games for MiSTery. No more access-speed problem. Enjoy

THX a lot!!!

Thanks very much!

Many thanks for the new MiSTery core ! Thanks too for the 3GB image.

Many thanks, this one is even bigger than the last one, wow.

Hello, because I wanted to test some games that load slow, I found a way to speed up the floppy drive loading by tweaking some values to their limits. But, for now I don't know if that reduces compatibility. If someone is interested I can send the binary and/or modifications here. That's only tweaks, nothing professionnal.

Disk slowness is from the core or it's accurate? I sold 4 years ago my Mega STE and I don't remember...

[Kolchak]

I am not sure but I guess it should be accurate.
For example Toki loaded slow with STE, TOS 1.62 and 1MB ram (with 512k it was a little faster). Now it runs fine with "turbo" on.
Maybe we can add sort of turbo floppy feature like on the Minimig core ?

Feel free to send a patch with turbo FDC mode. Note that the menu option would be added to the firmware.

Following on from sebdel's testing of various demos, I'm just reporting a couple of other issues that I've noticed, that might help with debugging.

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.

Oxygene - Nostalgic-o - Lemmings screen - in ST mode, at about 40 seconds into the scroller, it stutters and starts jumping around the screen (right around the time it says "AMIGAAAARRGH". STE mode is much better - although the scroller does occasionally stutter, it runs through okay.

Yeah I didn't report back but I've seen a lot of 'it corrupts eventually' symptoms. Did you notice the union demo scroller eventually stops working? (the main menu one that is duplicated throughout the demos)

Nott specifically, though I didn't leave the main screen on too long. I did notice that the main menu scroller is corrupted in STE mode, and toggling back to ST mode fixes it immediately.

I tried some demos today, the Bad Apple demo crashes right after start, it works on the other ST core.

Also, any chance to get Robocop 3 running, it doesn't work on any ST core.

EDIT: Correction The 2 disc version from the Bastards Robocop 3 works on TOS 1.04 and ST chipset, but on no other TOS, the game ran fine on a MegaSTE

Btw: what's the best self running demo? I'd like to do some demo setup that runs unattended and shows the ST's capabilities.

Just fixed the Electra demo. It has an automode!

What was it? Was it so specific that it doesn't fix any other demos? It kinda sucks if we are already at the point where you need to fix them one by one

It was just a reset issue. Yes, the core is at the point when one has to fix the bugs one by one.

...and by one you mean you
Just saw your fix for the European demos! Thanks for your relentless efforts.
