MiSTer FPGA Forum

Another issue I have found today whilst playing the Genesis Core on my MiSTer is with Total Football. The Menu music is completely scratchy and messed up compared to running the game on real hardware.

This is how it should sound

This is how it sounds on the MiSTer Genesis Core

I confirm, scratchy sound is real and there is something funny going on here.

What is even more interesting is that it only happens when ROM Storage option is set to either Auto or SDRAM. On DDR3 sound is ok. This suggests Auto puts this option to SDRAM when it detects SDRAM board.

In this topic viewtopic.php?f=16&t=3836 user aberu recommended SDRAM as more stable option. This case suggests otherwise.

In either case we probably need bug report for this issue

Doing RESET from the OSD seems to resolve this (for that particular playing time).

My tests
I. ROM Type: Auto
1st run just after loading ROM - scratchy audio
2nd run after reset - good audio
3rd after another reset - good audio

II. ROM Type: DDR3
1st run just after loading ROM - good audio
2nd run after reset - good audio
3rd after another reset - good audio

II. ROM Type: SDRAM
1st run just after loading ROM - scratchy audio
2nd run after reset - good audio
3rd after another reset - good audio

Looks like some kind of bug that affect ROM type SDRAM more than it does DDR3 but is imho more likely related to reset
