Hi,

I think I've discovered a couple of bugs in WinUAE (tested with 1.5.1). Can anyone confirm?

Emulation-related bugs first:

Delicate Sounds by Razor 1911 (ftp://ftp.amigascne.org/pub/amiga/Gr...icateSound.dms):
At the menu press F3 to select greetings, then F10. The text at the bottom of the screen is corrupted (but the reflection below it appears okay). That happens with cycle-exact timing, regardless of the emulated chipset (OCS, ECS Agnus, full ECS). No corruption on my ECS 1.3 A2000.
PMC Mega Demo by Pure Metal Coders (ftp://ftp.amigascne.org/pub/amiga/Gr...C-Megademo.DMS):
Boot and when the text about function keys appears press F7. Wait for the demo to load and decrunch, then press the LMB when prompted. There are problems with the upper part of the display, probably related to non-interlace to interlace mode switching. If you Alt-Tab out of then back to WinUAE the display corrects itself. (Notice also how the scrolling text at the bottom is almost unreadable due to the interlaced display. WinUAE's lack of an "interlaced scanlines" line mode which would make that readable is a bug in itself IMHO... )

Some other bugs/issues:

If WinUAE is started with the "Don't show taskbar button" box checked, and the user unchecks that option and minimises WinUAE, there is still no taskbar button.
When not showing a taskbar button, under Windows Vista, if the main window is minimised, it becomes a small title bar near the bottom left of the screen, just above the taskbar. If the user double-clicks the system tray icon to open the WinUAE settings window, then clicks Cancel, the mouse pointer is trapped in a small region of the screen below the minimised main window. If it has not been moved the pointer is trapped at the left side of the taskbar. If the minimised main window title bar has been moved up, the pointer is trapped in a small rectangle below it.
There are two problems with the floppy drive sound feature. Enable floppy drive sounds. Start emulation, boot a floppy disk and when the drive motor sound is playing, press F12. Change to CD32 in the Quickstart page. Notice that there are no emulated floppy drives now. Click Reset. The drive motor sound plays continuously. The second issue occurs if you start WinUAE, make sure floppy drive sounds are disabled, then boot a floppy disk. While it is loading press F12, enable floppy drive sounds and click OK. There is no drive motor sound, only the head movement sound. A good disk to demonstrate this is ftp://ftp.amigascne.org/pub/amiga/Gr...GameSound1.DMS. The drive motor stays on when the bouncing disk hand appears, so press F12 then.

Related to that, it would be good if there were an option to only play the head stepping sound, not the drive motor. Hearing the heads step can be helpful - you know when a program is loading - but many games and demos leave the drive motor on all the time.

[Is there a problem with running SANITY-BestGameSound1.DMS? It wouldn't load fully on my ECS A2000, but the background behind the song list flickers, regardless of the chipset used in WinUAE. Is there any real Amiga that it displays correctly on?]
