Re: Resourced TOS Rom

galahad, you've been given good advice and input in this thread. Some of it yes. While we're at it - I have browsed the entire TOS sources. No I won't share it with you - ever - OK, thanks for that, already got it elsewhere, but if I ever lose the source, i'll be sure to not ask you for a backup co...

Re: Resourced TOS Rom

What you want to do is the same as what EmuTOS does. The thing you need to do which EmuTOS doesn't is to add 16 color rendering. In your own words, you're only looking for system compliant games (I believe there might be one, I think I bought it with my first ST. I'm less sure there's two). EmuTOS ...

Re: Resourced TOS Rom

Why should I rewrite ALL TOS drawing routines when I can write ONE routine that will capture ALL redraw changes on the ST screen and convert to Amiga display? Even the mighty A500 can't do this at 50/60fps and leave a decent amount of bus bandwidth to the actual game (or application). ST games use ...

Re: Resourced TOS Rom

If these games _were_ system compliant, EmuTOS could run them. EmuTOS has everything drawing related TOS 1.02 has. But emphatically NOT in 16 colours on an Amiga which is my focus here. Not true. EmuTOS supports VDI and LineA (the TOS parts that handle drawing) in all ST screen resolutions (on the ...

Re: Resourced TOS Rom

This is plain and simple wrong. If EmuTOS isn't suitable for the A500, then why do you want to spend time on TOS 1.02 which is neither faster nor smaller than EmuTOS? And EmuTOS is already running on the Amiga. It isn't, EmuTOS is NOT coded for A500, or do you think A500 is replete with IDE interfa...

Re: Resourced TOS Rom

Its an incredible amount of work, whereas its easier to physically have the TOS rom in memory do all the hard work, and simply patch the routines that specifically need to be converted to make Amiga parameters valid for TOS, like redoing writing to colour registers, or the screen redraw routine etc...

Re: Resourced TOS Rom

EMUTOS isn't designed for a lowly A500 Why do you think so? EmuTOS is running perfectly on an 8MHz ST here, so why shouldn't the superior Amiga keep up? ;) Especially since the only games you'll get running are games that's 100% AES/VDI based. Seriously, the only reason for *not* using EmuTOS for t...

Then intention is to redo TOS 1.02 and have it work as fast as possible on a 68000 Amiga, so that all of the games that didn't make it to the Amiga but are TOS/GEM/BIOS dependent have a good chance of working, either that, or I have to write a custom mini TOS system so that it can run these games a...

$fa0000 is the cartridge space. Not the built-in ROM.

Re: Resourced TOS Rom

Did you know that EmuTOS already supports Amiga? Not a 1meg 68000 Amiga A500 it doesn't ;) EMUTOS is more suited to A1200 and the like, it has virtually no optimization whatsoever for the Amiga version. I'm not interested in necessarily doing a full blown ST emulator, but there was a lot of softwar...

Has anyone ever resourced an Atari ST TOS ROM back to ASM source code? I have a project in mind, and I'm not really that enthused with binary hacking the ROM to do what I want, and rather than re-invent the wheel, would be nice if someone has resourced it 100% cleanly then maybe I can use that inste...

Its not that people don't take the A1200 seriously as a stock machine, its still pretty capable, No so pretty. The main problem is the limited RAM size for a prodution work in workbench.

The ChipRAM is of course used by the CPU, becuase all the graphics data, samples, I/O registes and ports are there. You are completely wrong.

Re: resourcing ST programs

Don't really understand, but you are either in need of a resource editor like Interface or Resource Master, both here: https://sites.google.com/site/stessential/system-tools or.. more likely, you need a disassembler, probably devpac, stdigger, easy4 and dasm68 https://sites.google.com/site/stessent...
