Latest version of ScummVM ported to AGA

[pintcat]

Um... I think the only option I changed is 'AUTO_SELECT_AUDIO_DEVICE' to FALSE. This gives me a requester so I can select the appropriate mode myself every time. It would be nice if I could set a specific audio mode via command line (or tool type). The same with the screen mode. But the most interesting feature would be if I could automatically start one of the listed games on a command line.
Btw: I think I found a little something when I tried to add a new game to the latest version (1.3.1.022): On the file browser I wanted to reach the volumes list so I clicked on 'Go Up' several times. When I reached the root directory of my partition and clicked 'Go Up' one more time the program crashed.
I'm using the 060-AGA version of ScummVM.

I would like to have adlib emulation driver selectable in 030 AGA version (aminet 1.3.1.031) cause i don't have fpu (aca 1231). 040 and 060 AGA versions seems to have that option in options/audio/Preferred dev. And also audio selectable tooltype too... Otherwise , thankyou for absolutely amazing port !

[Retrofan]

Sorry, I haven't read all the post but some, but I want to use the 030 version with my ACA. I've got some doubts:
-I've heard I can't play Full Throttle... (I tried it some time ago). Even with PFS3 and a Fast Ata? . What games can I try?
-Do I have to select first any special screen mode? Can I try with Superplus?
-Do I have to change the AHI preferences?

Thanks master

Cool, always nice to hear from people enjoying my software and using their Amiga's

I had to disable MIDI emulation in the 030 ports as the CPU is just too slow but people were still trying to use it.

Hiya,

Yes Full Throttle is not playable on an 030 I'm afraid, not even with a super-fast ACA. The problem is the infamous fight scenes which are basically interactive rendered movies streamed off the hard drive

The rest of the game is completely playable but these fight scenes kill it on an 030. You need both a fast processor (eg 40Mhz 040) and a fast hard drive transfer rate (SCSI, IdeFix Express) to play Full Throttle on the Amiga. Interesting even the PPC port struggled with the fight scenes but they run fast on my port with an 060

Check out the speed right here -> fight


As to your setup questions, for max performance on an 030 do the following:

• Install AHI 4.8
• Set you AHI device to 8bit FAST Stereo++ @ 8000Hz
• Patch your memory copy routines to 030 versions
• Load your ROM to FASTRAM (easy with an ACA)
• Install PFS3
• Use a PAL screen mode (Tooltypes), sorry SuperPlus is not supported.

ScummVM v1.4.1 ported to AGA (040/060 only)

RTG version should be ready next next week.

I have a weird question that's probably more theoretical (as it would require changing the way ScummVM works).
Could you stream those files from the RAM disk.
I mean, even with the 128M RAM cards (mine "only" has 64M), you can't play all of Full Throttle from the RAM disk, but could you move just those fight sequence files to the RAM disk, so they don't have the IDE and CPU hits associated with IDE?

And would it make enough of a difference?

Just a weird thought I had.. ;-)

Another question about 030. You say

Can't it make it for me? I mean, just use it that way and later leave it as it was.

No, not possible sorry, the AHI API is a bit limited

If you use the high-level API you can do this kind of thing but I have to use the low-level API to create a separate sound thread. The separate sound thread is needed to avoid contention issues (which is a nasty bug my old versions of ScummVM used to have).

As a side note, I think these will be my last ports of ScummVM to Classic Amiga's I'm afraid, ScummVM is getting harder to port to Classic's with each update.

[Xenon]

Novacoder, your work is great Don't worry if new ScummVM versions can't be ported to Classic Amigas, because we will continue enjoying the games with your ports

I get error with ScummVM 040 AGA:

Smartfilesystem (scsi.device, unit 0)

findextendbnode: line 2153 findbnode() can't find key 16255716!
error=0 *returned _bnode=01122EBA (*returned_bnode)->key=4815469

I'vent actually tried RTG version, because I use CGX, so it doesn't start, is this fixed some day?

[NovaCoder]

Are you actually using the latest versions?

RTG uses CGX not P96. Make sure you have a 320*240 8bit screen mode setup. You can also check the error log file.

[utri007]

I'm using latest versions.

I've 320x240 8bit screen setupped to prefs.

[utri007]

Error log actually says that it can't open 320x200 screen. I have that screen enable in prefs. I've all typical sreens enabled 320x200, 320x240, 320x256 and all of them 8, 15 and 16bit screen depths

That's strange, works fine for me under WinUAE.

Out of curiosity, what part of it is getting more difficult?

With each release of ScummVM the core team add more support for enhanced capabilities which are just not possible on the classic Amiga. Each release is also a little slower than the one before it because the team are more interested in nicely written C++ code than squeezing every drop of performance they can out of the CPU.

And finally, the Amiga compilers aren't getting any younger, this also makes it harder as the team add features that are only supported on newer C++ compilers.

Saying that, I did notice the other day that they are adding support for Eye of the Beholder 1 & 2 for the next release

Westwood was using SCUMM too? Then maybe Command & Conquer will be supported some day...
