Re: 0MHz DOS Collection 2024.03.20 Released

The main problem is Dos is quite limited and there were no standards: almost every game saved its data in its own way. Sure, something can be done, it's a lot of work, because each game must dealt with some custom treatment but, for example, it might be possible to do something like this, see two possible approaches: 1) A separate .VHD used for sav...

Re: N64 Core Development Ends

In addition to that, since the N64 Core is released under the GPL license, even assuming Analog will use it (which doesn't seem the case, and that's another good reason why it's best to get facts first before assuming anything), they would be completely in the clear using it, as long they'll comply with the GPL license, which means open sourcing an...

The project is using a straight foward basic DOS setup that is applied to all games, with some smaller changes for some particular titles. Sorry, but isn't this kind of contradicting the main point of this collection that each game can have a completely different Dos configuration without affecting the other games? That's the main attraction of pa...

Re: DOSContainer Alpha Release

Nice so, you are creating .VHDs programmatically, right?

Have you considered some kind of variable parameter to tell, game by game, how much extra free space each game might need when running? I found a couple of cases where the .VHD was made so tight, so the game started, but didn't have enough space for the Saved games.

DR-DOS is better at freeing conventional memory than MS ever was. That may help.

I tried the method of starting MISTERFS, copying the relevant files from the Shared folder then MISTERFS /u to unload it, and it seems to work fine.

Re: 0MHz DOS Collection 2024.03.20 Released

Maybe using the support for the /shared drive in the core would be the better/easier way? That’s what we do for AmigaVision, it could just be a single file in that directory on the MiSTer SD card that lets the system know whether to configure for MT-32 or not. I'll try that, the main issue is the MISTERFS.EXE takes a bit of conventional memory, wh...

Re: 0MHz DOS Collection 2024.03.20 Released

I don't know exactly how this might work, if we really need to inject a whole file, or if could at least send some kind of signal from the outside, which the Ms-Dos that runs in the core might use.

Is there anything in the AO486.CFG that might affect something in the core that might be read from Ms-Dos?

As an interesting fact, Mister is (AFAIK), the only place where you can use the original, uncracked (and not-crashing) Cubase 3.01, without a dongle, because it's emulated in the core!

If it's not powerful enough, then how would it cope using the Mister Groovy core ?

The CPU might be powerful enough to emulate, but with not enough GPU power to run shaders or post process. This core allows to skip the gpu, it's like an e-gpu, basically.

Re: Groovy_MiSTer Core

Eh ? What would be the point of this ? You can already do this, natively, with the PC running the original emulation, and shaders running on the PC. Bizarre. What if the PC is not powerful enough to run emulation + shaders? Like a RPI that might be fine to run the emulation, but might not be able to afford extra shaders, not with fps drops at least.

There are certainly many (MANY!) latency benefits...I was referring purely to accuracy.

I consider latency (audio, video and input) as a part of overall accuracy so, with all with other things being equal from the "emulation" side of things, I'd still consider a less laggy solution to be more accurate just because of that.
