Fix info and vampire incompatibilities!

[lord of time]

This issue is bugging the hell outta me - I can't be the only person to have come across it? Perhaps we should put our heads together and figure out a fix?

The Indivision is supposed to be compatible.

Well it's not - I have it from the guys at that very forum in there is room

whats the issue mate?

[AlgoRythmic]

I have an Indivision and a Vamp 500 V2 installed in my A500 Plus and they're totally compatible - never had any probs whatsoever. I even have a 1MB chip upgrade in the trapdoor..

What kind of incompatibilities are you experiencing exactly?

The indivision config software will not detect the indivision when the vampire is installed... apparently it's to do with registers?

Yes, the registers that the Indivision added to the Amiga register address space are not accessible from the 080 because it has its own range of overlay registers. This was communicated clearly right from the start. Then people started to notice that the Indivision still worked nonetheless but that was only true during an early state of the Vampire core. Now with more and more SAGA features being implemented, the Indivision registers are not accessible any more. I wonder whether this really matters as the Vampire's RTG is far more powerful than the Indivision's additions. The Indivision should still work as a scandoubler if I'm not mistaken.

Yes but I can't tweak the settings when I should be able to. Nowhere has it been said clearly that I can find that the indi and the vamp conflict surely there is a way to fix this and no saga is only good for rtg as no native output at the moment.

Doesn't Gold3 make scan doublers unnecessary? I've ended my search for an affordable scan doubler or 15Khz monitor and am using the RCA video out because of what I've seen, read and heard about Gold3 beta. Am I mistaken to assume I won't need these things once Gold3 is stable and released? (NOTE: I do not yet have my allocated card - should be here in a few months).

yeah, i think your right.

GOLD3 will output everything, even all native modes across HDMI, so need for a doubler, well, thats my logic on it to.

Yes, chances are that Gold3 will remove the necessity of using a scandoubler. A lot of stuff works very well already but we just cannot know now whether compatibility of a much faster chipset can get close enough to or even reach 100% which is why there is also work being done on the Parasite video digitiser in parallel to the core implementation. The Parasite will be open-sourced when it's done which means that anyone could build a digital video converter for an Amiga for very little money (I believe parts are less than 20€).

if that's the case, does that mean faster rendering of images, games etc. if its all out of HDMI ??

apart from viewing Amiga native modes over HDMI, what other advantages will it have?


thanks

Yes, all graphics operations are many, many times faster than before. This doesn't mean you will be getting 100 fps in, say, Shadow of the Beast, though, as the framerate has always been 50 fps and cannot increase. Games like Syndicate which crawls with a hundred or more enemies in the scenario will probably speed up, on the other hand. It depends on the type of game. E.g. ADoom running on a native display instead of RTG reaches much higher framerates than on the real ECS chipset mode. Of course, ADoom will still run better on RTG because it just doesn't need the chunky-to-planar conversion anymore, the chunky-to-planar conversion just is a much smaller penalty with fast chipmem.

Workbench and all OS-software is amazingly fast even without any necessity of RTG support. New games could do hundred times as many blitter objects as before or use hires instead of lores.

nice, so games that DONT have a cap, because they are meant for expanded Amiga's namely 3D shooters, should rocket along.

Guys your missing the point - GOLD 3 isn't available yet... until it is I gotta use the indy

there you go, from what i can read, and i could be wrong, going to an older version of the core update might fix it, as those registers are usable in an earlier build. it looks like the answer might be :

"Wait for GOLD3 and use RTG over HDMI with no need for a scandoubler"

i would rather use an old CRT myself, i prefer them, but there you go. i know its not the answer you where looking for, its the only answer on this thread that i could find.

Yes, that's true, one of the later SILVER cores would probably work with the Indivision.

The next core will have CRT-scanline emulation for lores modes, how is that? I understand the appeal of the original hardware but I am glad that I don't also have to hunt down a compatible CRT (no idea where mine went when I put my Amiga on the atic, it was the last CRT I ever owned...)

TBH Grond, its more about the interpolation of pixels on text on screen, a CRT is slightly fuzzier, and the image isn't as "hard edged", as it is on an LED screen

Yes, that's why the CRT emulation also does some filtering among the pixels...

you really do think of everything, dont you

when is G3 likely available?
