Latest version of ScummVM also ported to RTG
 

Overview:

ScummVM is an interpreter that allows you to run certain classic graphical
point-and-click adventure games on an Amiga (provided you have their data
files). The clever part about this: ScummVM just replaces the executables
shipped with the games, allowing you to play them on systems for which they
were never designed! This Amiga ScummVM port only supports certain ScummVM
game engines (see About Box within the ScummVM Launcher).


Requirements:

1) An RTG Amiga.
2) 68060 processor or better.
3) 64MB of RAM.
4) AHI installed and configured (see links section below).
5) Music packs for digital music playback (see links section below).
6) CAMD library installed and configured for native MIDI playback (see links
section below).
7) The original games (or demos).


Features:

* Double buffered 16 bit SFX and speech
* Fullscreen and window mode support
* MIDI music emulation (no hardware required)
* Double buffered 256 color graphics
* External MIDI support (using the CAMD library)
* 16 bit GUI (converted to 8 bit in real-time!)
* Screen shake (and it actually works this time)
* Back ported OS4, MorphOS and AROS code
* Compressed music support (OGG/WAV)


Configuration:

The you will need to use the ScummVM Launcher to update
the paths (save/theme/extra).

You can also manually add the following to your own INI file:
The 'close_wb' configuration option can be used to close the Workbench.
The 'mixer_priority' configuration option can be used set the mixer thread
priority.

There are various configuration options within the ScummVM Launcher (see
the official ScummVM readme for more details).

When running from the Shell you must specify a stack of at least 300,000.
The AHI device used will be the one setup in your AHI Prefs (unit 0).
You will need to install the CAMD library if you want to use an external MIDI
device.

You will need to have 320x200, 320x240 and 640x480 RTG 8 bit screen modes
available to Workbench.

The mouse will automatically lock (Press CTRL+m to unlock).


Performance Considerations:

1) If you have a Blizzard you should really be using BlizKick, Apollo users
should be using RemApollo.
2) Fast File System is actually really slow, use PFS3 instead.
3) Playing OGG compressed music on a real Amiga will be very slow, try using
WAV files instead (or MIDI).
4) Use v4.18 of AHI as the later versions are too slow on real hardware.
5) If you are using Paula stick with the 'FAST' 8 bit Mono/Stereo++ modes.
6) Try reducing the audio playback frequency down to 8k if you're still having
performance issues.
7) Running in a window with an 8 bit screen mode will be very slow.


Limitations:

1) FLAC compressed audio/music files are not supported.


Thanks and acknowledgments:

The ScummVM developers, my mother, the UtilityBase crew for help and advice.
Minuous for the awesome installers and the EAB beta testers especially DDNI and Rockersuke who went above and beyond the call of duty.

"couple of days" my ass ;) It's online now.

Did you recieve our mails (from aminet@aminet.net)? You will have to reupload ScummVM_AGA.lha, the archive was corrupt. And please provide *seperate* readmes in the future, otherwise our scripts ignore your uploads.

Damn nice job, thanks.

Hiya,

Thanks, I'll send you a mail about the other points.

i placed this news about your ports on amigascene.nl and asked people to try out different ports you made for different setups, and that they will join here and give their comments/opinions, thanx novacoder..

Awesome stuff, look forward to trying this one :D

New faster (I hope) version uploaded to AmiNet.

The funny thing is the the AGA version is quicker under WinUAE than the RTG version most of the time ;)

It seems much more popular as well based on the threads ;)

Still meaning to give this a go on my rig, its in bits at the moment waiting for an upgrade...

Keep up the great work :great

Steve.

Cool, I would love to know how it runs on a real miggy. Can you test Simon the Sorcerer 1 & 2, Full Throttle and Beneath a steel sky when you get it setup.

Next version will also support AGI games ;)

I tried to give a try to this version , but the only result when I run it is what you see on the attached image...

my configuration is: A4k/cyberstorm mk1 060/128MB/CV64/OS3.9 ...

thx

Hiya,

What do you have your screen mode set to?

From the look of the screen-grab it looks like you're running in a very low resolution. Either try editing the INI file and set 'gfx_mode=1x' or increase your WB resolution up to say 1024x768.

hey!!

thanx!!! this and also the fullscreen option works!!

chris

The 030 version doesn't work with my ACA056. I only get a black screen, and after changing the tools to false still I can't find a resolution that works. If I wait around 4 minutes I can see the screen but very bad, and it doesn't let me select anything.

Wow you got the fullscreen option to work, that's great most people can't get it working....what's the trick?

Did performance increase fullscreen vs running it in a window?

Can you also try the graphical filters for me to see if they work?

A video would be nice, nobody has done one of the RTG version yet, just the AGA version. :D

I'm getting the following error in the log file:
Could not initialize SDL: Found no sufficiently capable CGX visuals!
I'm using an A1200 + Mediator + Voodoo with P96 software and I have video modes available ranging from 320x240x8 to 1600x1200x16 all tested and working. The OS is 3.9 and I'm using an Apollo1260@50 with 64Mb RAM.

SOLVED!
Just copy these 2 libraries from the Picasso96 2.1c (alpha) distribution:
LIBS:Picasso96/emulation.library
LIBS:Picasso96API.library

Cool glad you got it working, have fun :)

I've been trying different options and such, and I don't think the slowness is due to the music. I can disable it completely and the gameplay remains just as choppy. Also using a soundcard or Paula doesn't make much difference (I had to change my AHI settings for this, is there a way to get an audio device requester?). As rockersuke pointed out in the thread related to the AGA version, Doom is fairly smooth even on '030s with music and sound effects enabled, whereas this ScummVM port tends to be quite slow. Perhaps this has to do with SDL, which Doom obviously doesn't rely upon. Full screen doesn't work for me and I think that would be the way to go to gain some speed. Let's hope Novacoder manages to get it working.
One more thing: sometimes when I quit ScummVM, the (empty) window remains on the screen and doesn't go away anymore, no matter what I do.
Edit: I think xc8 could tell us his HW/SW configuration, so that we get a clue as to why he got fullscreen working!

Hiya,

The only hint I can give you about getting the RTG version running in fullscreen is this from another user as I've never managed to get it working myself :shocked

And you are correct, getting it to run in fullscreen is your best bet for more speed.

We did find that certain games (eg DiscWorld) seem to play MIDI better than some other games. If I ever get the time and energy I might port a faster MIDI engine over to ScummVM which could be used in both the RTG and AGA versions.

I cannot do anything else to make this RTG port faster, I only did this RTG version because it was very easy for me to do using the 68k SDL, my real interest is in AGA. Unfortunately the old 68k SDL is no longer maintained which means that this port isn't ever going to get any better :(


BTW Amiga Doom does not use MIDI (I should know, see the DOTT thread) so that's not a good comparision. I think the problem here is that the modern versions of ScummVM are targeted at more powerful hardware and so they don't have the same issues as the Amiga versions with things like MIDI playback and 16bit overlays.

Testing with Dott, Fullscreen does work ok in rtg version on my Bvision. Too slow though on 040/25 :/ scaler set to Normal (off)

I'm the one to blame for mentioning ADoom at the ScummVM AGA thread :o which of course I did without the intention to cause any harm. But ADoom in fact does play MIDI files, I mean, the .mus files contained inside Doom wad files which are a slight variant of MIDI. And it does so using a MIDI engine, as stated in ADoom's docs. What's more, since Doom executable version 1.5 (and ADoom uses 1.9) you can use MIDI files directly in wad files without converting it to .mus.
Even if we still don't consider that as actually playing MIDI I made a little experiment last night. I downloaded and installed GMPLay from aminet. I left it playing a bunch of MIDI files as a background task and started ADoom, disabling all of its sound features (both sfxs and MIDI music) to avoid a sound conflict... and it worked! FPS average decreased from some 10-15 to 8-13, making the game hardly playable, but It still was going on.

Now, playing MIDI files without external hardware has always been considered as a real tricky business for any 680xx Amiga, even for 68060 based ones. Then again, a 50 MHz 68030 can play MIDI files using software synthesys and still have left some amount of resources to do other things, including playing Doom at a fair enough (given circumstances) speed.

I really am sorry and apologize if it seemed that my intention was either beeing dismissive of Amiga ScummVM's music performance or making unfair comparisions. My point was that it's not just lack of power on the processor side but, as Novacoder himself has quite acurately stated, the fact that the original ScummVM routines are meant to give optimal results with a later generation of CPUs what causes the poor MIDI output even when using an external card (as seem to be the case). This last bit suggests that perhaps there could be still an unexplored space for improvement. And then again, that doesn´t mean Novacoder should even think of it. As it is, Amiga ScummVM has reached far beyond than we were all expecting not long ago and has given us much more than we ever asked for, and of course, we'll never thank him enough for it :great.
