Megademo from Red Sector Inc make fs-uae 2.5.11 dev crash

[Marskilla]

I had a lot of troubles to make the Red Sector megademo work.

Maybe the home made loading system...

Anyway the config file I used was this one, and it worked perfectly with fs-uae 2.4.1.

With 2.5.11 dev I have this :

And here is the config file :

Is there a way to make it work with 2.4.1 and 2.5.11 dev ?

Why do you always use so many (in this case) useless uae_ options? Especially many of the uae_gfx_* options are totally stupid and make fs-uae crash. A minimal config could also solve the other problems you posted in the forum.

A working config is:

[config]
floppy_drive_0 = rsi-a.adf
floppy_image_0 = rsi-b.adf

This version works as it should:

I found the problem causing the crash. The following options are not specified in a valid way:
* uae_cpu_compatible = 1
* uae_cycle_exact = 1
(they should be set to true, not 1)

This causes the CPU to be neither cycle exact nor compatible, and there is a bug in WinUAE 2.9.0beta10 / FS-UAE 2.5.11dev causing "non-compatible" 68000 cpu to crash. This seems to be already independently discovered and fixed in WinUAE 2.9.0beta11:
"- 68000 + no cycle exact and no "more compatible" used wrong memory access method. (b9)"

Anyway, as jbl007 correctly notes, you are just making life difficult for yourself by including lots of unnecessary options. For example, using uae_immediate_blits = 0 with Amiga 500 will just make the emulation less accurate.

Adding extra options (and *especially* uae_ options) should only be done when each extra options has a clear purpose

Bypassing the FS-UAE video configuration by using uae_gfx_* options may also confuse FS-UAE, while some uae_gfx_* options are simply ignored. You should only use uae_ options to tweak the Amiga hardware where FS-UAE itself does not provide the options you require.

ok, I downloaded the adf you posted, here is my config :

[config]
amiga_model = A500
kickstart_file = Kickstart v1.3 rev 34.5 (1987)(Commodore)(A500-A1000-A2000-CDTV).zip
kickstarts_dir = .\kickstarts\
window_width = 752
window_height = 572
fsaa = 4
keep_aspect = 1
video_sync_method = finish-swap-finish
floppies_dir = .\floppies\
fullscreen_mode = fullscreen-window
audio_buffer_target_bytes = 16384
floppy_image_0 = rsi-a.adf.zip
floppy_image_1 = rsi-b.adf.zip
floppy_drive_0 = rsi-a.adf.zip

And the demo loads, the scroller at the top keep scrolling but it never decrunches...

So I tried :

[config]
floppies_dir = .\floppies\
floppy_image_0 = rsi-a.adf.zip
floppy_image_1 = rsi-b.adf.zip
floppy_drive_0 = rsi-a.adf.zip

And it worked...

SoI ended up with the working config :

[config]
floppies_dir = .\floppies\
floppy_image_0 = Red Sector Inc - Megademo 1.adf.zip
floppy_image_1 = Red Sector Inc - Megademo 2.adf.zip
floppy_drive_0 = Red Sector Inc - Megademo 1.adf.zip
window_width = 752
window_height = 572
fsaa = 4
keep_aspect = 1
video_sync_method = finish-swap-finish
audio_buffer_target_bytes = 16384
fullscreen_mode = fullscreen-window

Conclusion, it does not work with :

amiga_model = A500
kickstart_file = Kickstart v1.3 rev 34.5 (1987)(Commodore)(A500-A1000-A2000-CDTV).zip
kickstarts_dir = .\kickstarts\

Ok with AROS and KO with kickstart 1.3 ? WTF ???

Works fine here. Impossible to comment your case without logs. Attach fs-uae.log.txt for the non-working case!
