Amiga questions you've always been too embarrassed to ask

I guess it's because there is no maintainer. I should really fix that

Yes, see Aminet.

These are NovaCoder's ports

Of course I checked Aminet but it's an old version. The ScummVM page doesn't even OS3. We should fix this.

So? Works fine for all LucasArt / LucasFilm games (including FM-Towns versions) plus others...

Yes the official ScummVM page doesn't show any support for OS3.

If you can : would be

trying to test a lot of commodore 64 with black screen, I've noticed that it can reach the boot screen even without some chips (sid, cia, cd4066) -obviously it will lack sound, no cursor, etc.).
is it possible to do with amigas or all the chips are required in order to boot up?

ScummVM for OS3 would be great! Not everybody uses WHDLoad and this would be a nice alternative for some really cool games.

what is the difference between rom chips 3.0 like i have in my a1200 and the newer versions 3.1 and 3.x ?. i only play games on a a1200 i have an AmiTek 8mb gfx card and i use a 16gb sandisk ide cf hard drive which should i buy next and why ?. pro's and cons pls .

How is playing them at a fraction of their intended speed a nice alternative?

Stop being silly and play these games on a PC.

You have an "AmiTek 8mb gfx card"? Are you sure about this?
I think it might only be a RAM expansion.

The newer ROM can help you with larger partitions on your cf-card. Otherwise it has no benefits for gaming.

If you are just in for the games, there isn’t really anything more you would need.

They run at full speed. I ported Sarien to the Amiga decades ago. The AGI engine in ScummVM is based Sarien (Leisure Suit Larry, King's Quest etc).

Why are you so negative in every single thread?

Denise probably isn't required (It does not have any critical read-only registers) but it isn't very useful because display would (still) be blank.. Possibly also CIA-B.

Other chips are required.

Well there's not much to be positive about is there?

[lordofchaos]

In regards to WinUAE. Is it the case the 68020 will never reach the accuracy of the 68000?

Being negative, often to the point of trolling, is a pretty common pastime in Amigaland for quite a number of people. I guess it makes them feel better about their own lives in some twisted fashion.

Out of interest, I'd have guessed that Paula might be removable. Obviously the floppy disk won't work, but could such a system run off HDD?

[Rotareneg]

Paula handles interrupts. And if you remove Agnus, my pick for #1 critical missing function would be the processor clock, good luck getting anything done without a running CPU.

[roondar]

Ahem... I feel 'a bit' silly now... I did know that as I've been coding with interrupts the past few months but err, forgot when writing that post.

Most likely, unless someone finds someone who knows someone (add more steps if needed) who designed/developed the chip and has diagrams/remembers how instruction scheduling etc actually works.

Original source (today it has been decapped and reverse-engineered) for accurate 68000 emulation was US patent that included internal microcode diagrams. Also it was very simple compared to 68020+.

(It also seems only Atari Falcon and Amiga requires accurate 68020/030 emulation?)

[lordofchaos]

Thanks for the explanation Toni. I`m sure it's been asked countless times by now. Does seem very unlikely for all those conditions to be met.
