It's still running without issues, closing in on 24 hours now and I've been playing about 3 hours of them myself. Haven't look at what the flag does, but would it be possible to have this like a setting programmatically at run-time? I already have a "performance" options so it could be presented the...

Yes, it's probably different behaviour between the demo and playing myself. What I do is that I play through the game (~50 minutes) then I leave it on running the attract sequence. I've now turned on he flag, and had the attract sequence running the whole night now without any issue. I played it thr...

Thanks!
I'll turn the flag on again and see. Maybe I was just lucky to not get the issue with the flag on? Will let you know of the outcome.

Was just about to write that there didn't seem to be an issue with the flag off either, when this happened. :( http://mix256.com/megadrive/crash.png Lasted for well over 10 hours, though. :) What I've done as well is to remove most of the compression on the sprites (using NONE in rescomp files). May...

Played for a few hours yesterday without any issues. Also, the game has an attract mode that plays parts of a few stages mixed with showing the title screen. So after I played yesterday I left the machine running all night. No issues has appeared in the morning. I've now set the halt flag to 0 and I...

This will give you 30fps: u16 tiles[40 * 28]; while (TRUE) { VDP_showFPS(TRUE); for (int i = 0; i < 28 * 40; i++) { tiles[i] = TILE_ATTR_FULL(PAL1, FALSE, FALSE, FALSE, random() % 16); } VDP_setTileMapDataRect(PLAN_B, tiles, 0,0, 40,28); VDP_waitVSync(); } This is slightly faster. But still 30fps: u...

It was a release build with the flag on.
I will play some more tonight, using this build, to make sure that the issue doesn't arise. Then I will turn the flag off again and do the same test.
Thanks!

Played all night yesterday with out any issues.
How should the sound be different?
I think I might hear a difference in the sfx playback, but I'm not sure. I guess that's a good thing?

If it would turn out to be more stable with the HALT_Z80_ON_DMA flag, what would I then do?

Yep, I just started D0 with 0x011111111 and increased it for each iteration in the loop. And yes, there were uninitialized vars in my input handling and also at a few other places. :oops: Still won't help me track down the strange bug. But at least the code is nicer now. :) Also I didn't try with th...

All sorts of strange behaviors when setting "randomizing" the ram. My gamepad input reading goes bonkers.
Perfect test. Thanks!

Thanks! I hex edited with NOPs in the clear ram loop and have a release build running here at work now. :) Could the rom file have "random" values if .text have variables that is not initialized? I was thinking that I have some variables in .text that isn't set properly, that would be in the "copy i...

I've been running several long runs in genskmod the last couple of days without getting any kind of error. On a real megadrive it can happen at any time. Seems like there could be an mem-init issue? Like I've forgotten to initialize a variable that should be zero. Gets a random value on real hw but ...

Had quite a long session in gens kmod yesterday, running a debug build. But the error didn't happen. I will try some more tonight.

Unfortunately I only get these kind of errors on real hardware. Don't think I ever saw it in any emulator nor on the retroad machine.
When it happens can be really random. I can play the game for hours without it happening but sometimes it can happen just after a few minutes.
