Are we likely to have ResidualVM (side-fork of ScummVM) like OS4 have?

I see it supports a few titles that were basically 3D type games, such as Grim Fandango, and Myst III, and Escape from Monkey Island, though it is only at version 0.21, but the source code seems to be available for it from:

http://residualvm.org/downloads/

Very unlikely given that the ScummVM port for MorphOS is still at 1.5.0 and not been updated in quite some time. It's very unlikely anyone is working on a Residual port.

Not true, Fab always updates his port here, it's just the ScummVM site-maintainer that is lazy. :)

We live and learn :)

I've been working on ResidualVM on linux a bit, first trying to make it "somehow usable at all" (Resizeable window? What's that? The original games ran only in 640x480, so you too shall be stuck with only that!)

(As clarification, the engine DOES support fullscreen in other resolutions too, but that's implemented so, the game is first rendered at 640x480, and then stretched to fill the screen. Looks worse than "drawing to full resolution to begin with", and won't work on MorphOS.)

Grim Fandango seems to work ok this far, Myst 3 is mostly broken (due to resolution logic only implemented elsewhere)

No idea if I could get it working on MorphOS. It's not really THAT usable on linux either (Well, Frim works, Myst3 doesn't)

If anyone else wants to take a look at the sources, I can provide them.

Hi Jupp,

Thanks for your insight, though I suspected as much about Myst 3 and Grim Fandango as that seems to be troublesome on the currently supported platforms anyway, but it would be nice to be able to add it to our supported software, though, for me, a modern office package is far more important than games software.

I just wondered if it was do-able at all for MorphOS, which it may be from what you have said, and if you get anywhere with it, or get offered any further support to enable it for our platform then I'd really like to know about any likelihood of it becoming useable on MorphOS.

So.... i look this ResidualVM 0.3.0

I compile it but OpenGL.... not same as AmigaOS4 or other platform

somebody has a doc on OpenGL (for MorphOS)... wish difference ?

Some errors :

macro glCreateProgramm passed 1 arguments, but takes just 0
GLAPI Gluint APIENTRY glCreateProgram(viod);

macro glUnlcokArraysEXT passed 1 arguments....
macro glDrawRangeElements
glCorlorTable
etc....

Take a look
Code:
In the past at least configure had problems with TinyGL's macros...
Well, we have no GLEW and no shader (requirement for STARK engine) but Grim should work.

so.... it's working in Software 3D render...

it's very slow :( and colors are corrupt

... but OpenGL.. i dont know how it's work.

I can put my source here, if someone can fix this.

in deed, i use this

I make another binary with opengl... yes (change maybe), but .... when i launch, OpenGL detect my card (R300) with wrong color...

Maybe a driver bug? I need a few lines of code for a report.
BTW I'm using a 16 bit screen but some SDL games have no high colour support and I get wrong colours.

hi all,

I compile the last git sources code of ResidualVM

I test : Myst 3 and Grim, works but somes glishes :(
but i dont known enought opengl to fix that.. if someone can help

Well you've made some progress, and I hope someone can help you out with the OpenGL issues/glitches you're stuck with currently to get it running smoothly, and error free.

i publish this version.... i see if someone can help with opengl.

now i try to recompile scummvm with OpenGL render.... why not lol

Give it a go, and I've got my digits crossed - so the 2 is on the left of 1, and the 4 is on the left of 3, etc.

No wonder I'm confused half the time ... I just need some New Sense, rather than being a NuiSance.

Any chance someone can help beworld iron out the glitches on his port? Having residualVM fully working would be so cool and we are so close :)

I was running Myst III: Exile, and had just got past the point where the woman appears and sets fire to the room containing the Releeshan book, and steals it, and disappears to the island and you as the player follow her to the aerial platform where she opens/closes the door but once you try to move towards that door, or even onto the platform the following error is generated, and the program exits/quits.

How do you know the glitches are in the port? It is unfinished software.

From the fact that the glitches don't occur on other platforms, I guess.

You mean the very specific glitches reported in this thread are also mentioned on the Github page?

No, they're mentioned in the forums.

Still lots of lingering bugs with OpenGL, so it's going to be really hard to know which are due to MorphOS and which are due to the code, and which are due to the code but only triggered on MorphOS.

Thread is from 2015/2016, MorphOS version uses 2018 snapshot of code base, so might not mean much.

As insinuated, the first thing to do, at least in my opinion, would be to run the same code base as used for the MorphOS version on a mainstream OS like Windows. If the glitch is there as well, then it can't be (easily) helped. If it is not, then the MorphOS porter might be able to do something about it.
