Floppy keeps spinning after fread

Yes, exactly.

Must check this evening from WinUAE when I'll be at home, showing floppy LEDs on FS-Uae requires a configuration procedure that is quite mad.

According to WinUAE emulation, the floppy light remains always on even when the spin sound stops. Turns back off only when I quit my game and go back to CLI.

Since I noticed you are using my "ptplayer" you should know that this is not a recommended use case. From the

ptplayer.readme

:

  This player is intended for games/demos which take over the hardware
  and disable the OS.

When calling

mt_install_cia()

it will replace the level-6 interrupt vector at

VBR+$78

. This also replaces any previous AmigaOS interrupt handler for level-6 interrupts. I guess this is the source for your problems with timer.device and trackdisk.device under AmigaOS.

Solution: Take over the whole machine or use an OS-friendly PT-player.

Thank you for your kind support, but I think this is not the case. The problem is exactly the same even if I don't use ptplayer at all. (See my previous post)

Honestly this is the first time I try a "OS friendly" approach in C and the first time I read assets in memory from disk, I come from "old school" ways of coding, I've always coded in assembly with asmone and every asset included with incbins...

Even if, in this game, my goal is to load everything I need from files and then call Forbid() to get maximum performance.

Found!!!

THIS was the problem:

SetTaskPri(FindTask(NULL), TASK_PRIORITY);

At the start of the program I was setting the task priority to 127 in order to have full priority, removing this everything works ok, I absolutely have no idea why...
In any case, probably this instruction is a nonsense since I call Forbid() after finishing with disk read...

So, the correct flow is:

• Read everything from files
• Wait some seconds
• Call Forbid()

The LED related hint by Galahad/FLT was VITAL, thank you my friend, you will be acknowledged in my very alpha-stage and work in progress C Amiga Engine.
