Mario Bros Always Resets to title screen after starting Game
So u can never play it i tried 2 dif rom sets and still the same issue why ?

[Gryzor]

I‘ve just played the game and it works as intended.
Preferably run the updateall script, instead of fiddling around with different romsets.

I've been seeing this issue as well. About once in 4 or 5 tries I can complete a game without it returning to the attract screen, but most of the time right about the time I start the second stage it just resets to the attract screen mid-game.

Not sure if the core needs the SDRAM module, but I don't have one installed. Was also wondering if it could be heat-related?

[retrodroid]

I upgraded my MiSTer power supply to a 4a one as a test, but still seeing issues with this core.

Out of 2 games the first one Mario froze mid-jump on level 2, the enemies continued to animate, etc. Second game, it reset the the attract mode after about 20 seconds of gameplay on level 1.

Totally just realized this was referring to the arcade game, not the NES game (NES core requires SDRAM). This could be heat-related if you have no cooling at all on your MiSTer; if you don't, I very highly recommend at least a heatsink, but the IO boards have fans as well to help keep things cool.

[retrodroid]

re: heat my setup has a fan on the IO board, but no heat sink on the chip.

I have a heat-sink on order, will retest once it is in place, though I don't see similar issues with other arcade cores, even after 30 mins+ of use.

UPDATE: Installed a 128MB SDRAM module which tests clean at 140Mhz for hours. No change in behaviour. Game continues to reset very frequently.

[retrodroid]

For kicks I tried manually deleting my .mra, .rbf, and rom files and re-ran the update_all script. It downloaded the MarioBros_20200627.rbf file, is this the latest release?

I still see various forms of lockups/resets within 2 levels or so when playing this game (via VGA arcade monitor), which is making me sad.

Any suggestions?

I'm trying to resolve the instability of the core.
Could anyone facing random issues test attached build?

[Hackshed_Carl]

This may be a mad idea but have you checked your key mappings in case you've accidentally got reset mapped to a specific button or combination of buttons?
Not near my MiSTer to test right now but it came to mind so thought I'd share

@Hackshed_Carl
I'm afraid that it is not likely, I think.

I found out the core contains designs which can cause instability.
Not only the reset issue, but various types of random glitches are reported.
I also experienced:
- Reset
- Corrupted sprites
- Cannot proceed to the next stage even though defeated all the enemies

[retrodroid]

Thank-you for working on this!

I'll test the new build today and report back. Are you simply looking to see if any issues are noted?

[retrodroid]

Good news! I played one game and got to level 10 without any issues at all. Game ended normally.

EDIT-> Played about a dozen games last night with zero issues!

[bellwood420]

Are you simply looking to see if any issues are noted?

Yes.
Before opening a PR on GitHub, I want to make sure that the issues have been solved, not only on my device, but on some other devices, especially the one that was having the issues.
The instability varied from device to device. Technically, it also varies with each build.
I tried to fix it to work stably on any devices and any builds.

Good news! I played one game and got to level 10 without any issues at all. Game ended normally.

Thank you for reporting! And you are skillful My best was phase 6...
