AmigaOS 3.2 and beyond

It's not just old games - new games have this problem. And the reason that you have not seen it reported, is this is the workflow:

(1) New game developed by developer using 3.1 and uses as much chip ram as possible, squeezing every last asset into ram to make the game as awesome as possible.

(2) User tries on 3.1.4 and game fails - complains to developer. Developer buys 3.1.4 roms, tests game - indeed 3.1.4 uses more chip ram than 3.1 - we assume for good reason - so developer removes assets from game, making game worse - now works in 3.1.4

At no point does anyone complain to the OS developers, because we all assumed it used more chip ram for a good reason!

Not so a small number of people that run Mac emulators on their Amigas can avoid a reboot, or so the OS developers can remove a "hack".

The regression is real - many people have put 3.1.4+ roms in Amigas with 1mb of chip ram - I wonder how many know the real reason they have less chip ram now ?

So instead of listening to coders and go the requested way, new implementation and bug fixing for the OS add more restrictions ... This is one of the smartest 'discours' I have ever heard .

Again, what is the problem? Developing for a 512K only machine? Sorry, not relevant for 3.2. The Os will require a bit more RAM, and it's really cheap to get these days.

It solves a convenience problem, and yes, that's more important than a 24K loss problem. RAM is cheap, and the Os needs in total a lot more RAM than 24K anyhow. Minimum specs for the Os is a bit more than 512K.

Which new games? The ones you make up for the sake of the argument?


Once again, be concrete. And no, I do not care about "demos".

In which concrete case is 24K an issue?

Then you better develop the game knowing the Os and its restrictions, and not trying to smart out the system. Or tell the user to use MoveMemLow. Not a problem either. There is no guarantee that a particular amount of RAM is available once the Os is under control. This is a multitasking system - you have always to consider the situation that you don't have all RAM available for you. How much RAM is available depends on which applications have been launched on the workbench, which other tools and extensions have been loaded, and the amount of RAM necessary for such tools is much larger than 24K. Os 3.2 is *not* for a 512K bare metal machine. Deal with it, that's not sufficient for providing new features.

So real that you couldn't come up with a single case where it matters, and where the reboot cannot be tolerated?



It's again one of those Amiga stories... Complaining for the sake of complaining. I provided even a solution.

@Thomas

It seems to me you do not understand Amiga game development. You don't realise the difference 24k can make to a game, or the efforts game developers will go to recover 24k. You also seem to not understand how many games work - booting from a floppy and trying to use all available ram while still taking advantage of OS functions (dos for example).

I am not going to list names of games that don't work - because ? They have been "fixed" and now work after being modified to work with less chip ram.

If a reboot can be tolerated for a gamer, why not for Mac emulation ? I wish game developers had the same inside track on the OS the Mac emulator writers have!

Is there even a legal Mac emulator available for purchase at the moment ?

(Read previous posts from 1899 to see how 'twilight zone' this answer is...)

I understand the principles of robust software development. Thank you, I do. That's part of my job. Yes, if you are so tight that 24K matters, you're doing something wrong.

I do not care. Get your job done, properly. Take care of the situation that you do not have all RAM. Do not make your software so tight, or provide reasonable requirements for it so it is not tight for your customer.

Which ones? Again, make an example. Your unwillingness or unabilitiy to provide one says more than anything else.

...you just want to complain. I fully understand. Troll off. Thank you.

Which games? There is really nothing on the table here. Stop the nonsense. I don't care about an abstract situation that makes no practical difference.

People own shapeshifter, people use it. People also use games. No issue. Just apparently nothing on the table where it matters. If you have a self-booting floppy with a game on it, and it really matters because the developer didn't know better, use MoveMemLow, put it there. It doesn't hurt on a non-3.1.4 system.

Wow - no need to start name calling - seems you are shooting the messenger?

You know my position - rebootless Mac emulation is not worth losing 24k of chip ram - your position is that it is.

I think we can leave it at that.

"de Charybde en Scilla".
Not that I am against hardware tuning (I did a lot BitD - gfx card, accelerator board, chip extension, fast ram extension, HD, ... - almost all my teenager money), but when it comes to the OS it has to target the most user base.
So the "I don't care non MAC emulators users" you are using is a speech from outer space...

If you want to encourage people upgrading their hardware, provide useful applications. Don't make the OS bloatware. We have enough of that kind already.

The current developers of AmigaOS 3 have followed this debate and will come up with a solution. It it our position that catering for MacOS emulation is not the job of AmigaOS.

What this means in detail we have yet to decide.

13.3 * I have now 28 KB less Chip RAM

When in the boot sequence is this allocated?
