New NSFe Player: Some files don't play audio unless "Initial RAM value" set to 0x00

[nelsonhef]

Hi!

During my tests, i found a couple of files that don't produce any sound in puNES 0.111 and later WIPs. They play fine in puNES 0.110.

• F-1 Sensation (Famicom NTSC): Outputs audio after setting "Initial RAM" to 0x00. Some tracks play incorrectly.
• Super Turrican (PAL): Outputs audio after setting "Initial RAM" to 0x00, but at NTSC speed. Plays OK after manually setting to PAL

Hi @nelsonhef, can you try the last WIP?

[nelsonhef]

Hi @punesemu, i tested WIP 4df298d and the initialization and region setting were fixed (Super Turrican plays fine), but F-1 Sensation still has problems. It starts to play but as soon as the second song ends, the third one, instead of the actual song plays a part of the second. Also, when on the first song, the player's "Next" button doesn't go to the next song but rather to other parts of the first song.

Thx @nelsonhef, as soon as I finish implementing the 562 mapper I will dedicate myself to solving this bug. Thank you very much for your reports, they are very detailed and this makes my debugging sessions much easier.

@nelsonhef can you try the last WIP? With the commit 8bf7379 I fixed 2 bugs, one of which could be the cause of the strange behavior of F-1 Sensation.

Hi @punesemu, i tested with the latest WIP 8bf7379 and unfortunately it didn't solve the issue. But i noticed something. If I disable the playlist, the songs play correctly at least until the end of the track list and then when it loops back to track 1 it starts playing wrong again. Another thing i hadn't noticed before was the track time/remaining time not updating correctly. I made two examples ilustrating the problem with the playlist on and off. Thank you for your efforts to fix these bugs and your kind words.

Really strange, I can't reproduce the timer problem.

[nelsonhef]

@punesemu, i was able to find the condition that triggers the timers issue. To reproduce it, load the NSFE, hit the Stop or Pause button and then "Turn off/Hard Reset/Soft Reset" the emulator. The timers will stop working.

Update: This timer issue occurs with any file, not just F1-Sensation and occurs even in puNES 0.110.

[punesemu]

Regarding the F-1 Sensation issue, can you try with the new WIP?

[punesemu]

And now I have also fixed the timers problem.

[nelsonhef]

Both issues were fixed in the latest WIP, thank you. Maybe i noticed another minor UI glitch. When you load a NSF file the "Fadeout" checkbox is selected and painted gray but if you Turn Off or Hard Reset the emulator it turns white.

[punesemu]

Thank you for your very thorough test, I will take a look at this issue as well.

[punesemu]

And with 74252de we should be done. :pray:

[nelsonhef]

Fixed. Thank you!
