Latest version of ScummVM also ported to ECS


ScummVM ECS 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!

ScummVM ECS only supports certain ScummVM game engines (due do performance issues)


1) An ECS Amiga with a fast 68030 processor
3) AHI installed
4) Some games or demos!


* 16 bit stereo digital SFX and speech
* MIDI music emulation (no hardware required)
* Double buffered 64 color ECS graphics conversion
* 16 bit GUI (converted to 6 bit in real-time!)
* Screen shake
* Back ported OS4, MorphOS and AROS code!

Performance Considerations:

1) You should always patch exec.library's CopyMem() and CopyMemQuick() routines
for faster processor specific versions.
2) Try reducing the audio playback frequency down to 8k if you're still having performance issues.
3) If you are using Paula, stick with the 'FAST' 8/14 bit modes for AHI (prefs) - a real 16 bit card *may* be faster with a 16 bit mode.
4) This interpreter really hits the hard drive so you'll need a fast transfer rate for the newer games (see below)
5) FFS is really really slow, use PFS3 instead
6) Loading your ROM into FASTRAM is a great idea (see below)
7) If you have a Blizzard you should really be using BlizKick to get most speed out of your Amiga, Apollo users should be using RemApollo.
8) Stick with v4.18 of AHI as the later versions are too slow

Thanks and acknowledgments:
Mikael Kalms for his help, advice and excellent C2P routines.
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.
